INTRODUCTION TO THE OVATION MULTICHANNEL

Ovation BioNatural™ pipettes are the ideal ergonomic solution for handling repetitive and complex liquid handling tasks that contribute to repetitive stress injuries in today’s laboratory. Ovation pipettes increase laboratory efficiency through automated liquid handling routines, while reducing fatigue and the effect of poor postures.
This manual describes how to use and care for your Ovation multichannel pipette.
As you can see from its appearance, it is different from every pipette that you have used before, therefore please read the instructions carefully.
Upon initial receipt of the pipette, the battery must be recharged for 90 minutes prior to use. (See instructions on page 5–2). Also, please activate the warranty on the VistaLab Technologies web site – www.vistalab.com. The required on-line form can be found in the “support” menu. Retain all packing materials in the event that the pipette is to be sent back to VistaLab Technologies for calibration verification or service.

Pipette Components

BIONATURAL PIPETTING

Introduction
Studies have shown that pipetting is the #1 cause of musculoskeletal disorders in the laboratory – it is, by nature, a repetitive process that puts strain on the body. While we can’t change how repetitive pipetting is, we can and did change how comfortable you are while doing it.
The Ovation BioNatural Pipette is the only pipette designed to keep your hand in the neutral position recommended by ergonomics experts. We call this BioNatural™ pipetting – it allows a lower hand location to ease stress in the shoulder, and a relaxed wrist angle eliminates uncomfortable extension and radial deviation movements in the arm. Force, velocity and exertion from repetition or duration have also been neutralized because of the Ovation pipette’s unique working position and reduced forces required during operation.
Some practice may be required to change years of posture and habits developed using standard axial pipettes; the physical benefits of BioNatural pipetting are worth the practice! When using the Ovation pipette, arm/hand elevation should not exceed 12” from the work surface, wrist rotation should not exceed 90º, and hand posture should remain relaxed with the wrist and back of hand slightly flexed.
PostureArm elevation remains low, minimizing stress to elbow, shoulder and neckWrist remains in a neutral range of motion throughout all pipetting operationsA loose, relaxed grip increases available strength in the hand, improving endurance and productivity during pipetting
Keep a “comfort zone” for pipettingErgonomics experts recommend establishing a “comfort zone” of movement for the task of pipetting. Position your body within 9” of the counter surface, and keep the items needed within easy reach. Ideally this should be 14” or less, and should not exceed 24” of occasional reaching. Wrist rotation should not exceed 90˚ from the work surface, and arm/hand elevations should not exceed 12”.

1. Relaxed shoulders and upper arms
2. Low thumb forces
3. Relaxed hand grip
4. Neutral forearm and wrist rotation
5. Low arm and elbow height

Ovation comfort-zone benefits:

1. Minimized tension and fatigue
2. Minimized exertion and contact stress
3. Low contact pressure
4. Lowest pressure in carpal tunnel and to median nerve
5. Minimized tension to shoulder and elbow

Picking Up the PipetteThe Ovation pipette has been designed to allow the body of the pipette to fill your palm. Rotate the adjustable hook to rest comfortably on your forefinger. The texture of the unit’s back helps reinforce correct hand positioning.
The unique ergonomic design and adjustable hook is compatible for both right and left-handed use.
Keep hand posture relaxed – there’s no need for a “firm grip” when using an Ovation pipette.
Selecting Liquid Handling Functions and Changing SettingsThe Ovation Multichannel pipette’s keypad is easy to use and provides access to all liquid handling functions and settings. Simply press the buttons on the keypad, monitoring the selection of functions or changes to settings on the LCD display.
Complete information and examples of all liquid handling functions and settings are included in “Operating Procedures” – Chapter 3 of this guide.
Acquiring Tips
While maintaining a flat wrist-hand posture, insert the Ovation pipette nozzles into a row of tips. If desired, place other hand on the textured surface (top) of the tip head and press down until you hear or feel a “click” and the indicator line on the tip head is hidden. This indicates that the tips are properly seated and ready for use.
The Ovation multichannel pipette has been especially designed to reduce muscular stress and fatigue commonly associated with single-handed tip acquisition devices. The Ovation design, recommmended by ergonomists and governmental agencies, allows the user to gently press on the tip head – thereby distributing forces and reducing fatigue and effort. Other pipettes do not offer this feature, and on many models pushing on the head would eject the tips.
Aspirating and DispensingSmooth gliding movements of the upper extremities with proper posture and minimal stress is the key to ergonomically correct pipetting. Maintain a low forearm elevation and neutral wrist posture throughout the pipetting cycle. Immerse pipette tips to an appropriate depth (1mm for 0.5–20µL, 2 to 3mm for 2µL–125µL & 5-250µL, and 2 to 4mm for 25–850µL).
Press & release the pipetting trigger to aspirate sample. Press pipetting trigger again to dispense or mix sample.
Ejecting TipsThe Ovation multichannel pipette stores energy captured during the acquisition of tips, and uses it to discard tips when the tip eject button is pressed. Point pipette tips into a suitable waste container and gently press the button. The ejector slide is activated, discarding all tips simultaneously.

Set-up of Liquid Handling Functions
Introduction
The Ovation multichannel pipette’s keypad is easy to use and provides access to all liquid handling functions and settings. Simply press the buttons on the keypad to step through the various functionss and make changes to settings. When a setting indicator is flashing, this indicates that the setting has been changed from a previously “saved” setting.
A number of settings, such as speed, count, and mix, appear in each liquid handling function. While their set-up is similar in all cases, they must be established independently within each liquid handling function.
Liquid Handling Functions
Pipette
The Ovation multichannel pipette provides three user-defined pre-sets for routine pipetting at exact volumes with overblow (TC or “to contain” pipetting). Volume and speed are stored for easy recall and use.

8. Aspirate sample by pressing and releasing the pipetting trigger. The total volume required to complete all dispenses and is displayed while the volume is being aspirated.
   
9. Press and release the pipetting trigger to dispense each aliquot. The display will indicate the volume being dispensed, and the number of dispenses remaining.
   To activate , press and hold the pipetting trigger when dispensing, and aliquots will be dispensed automatically at a timed interval until the pipetting trigger is released or the last dispense is performed. See the instructions to set-up or change the interval setting (page 3-9).
   
10. After the final volume is dispensed, purge appears on the display. Press and release the pipetting trigger to discard any remaining liquid in the tips.
    Note: purge can be used at any time to end any liquid handling function by pressing . To cancel purge, press again and resume dispensing.

Serial Dilute
The liquid handling function performs sequential dilutions. An initial sample volume is aspirated, dispensed into diluent and then mixed. The diluted sample is then aspirated for addition to the next diluent.
To set-up and run a Serial Dilute liquid handling function, follow these steps:
Example: Prepare a 1:2, 1:4, ,1:8 . . . serial dilution using a sample volume of 100µL. Mix 125µL of each dilution three times.

1. Use the liquid handling function to dispense 100µL of diluent into each sample well.

11. Aspirate 100µL of sample by pressing and releasing the pipetting trigger.
    
12. Place (filled) tips into the first diluent-filled row, and press and release the pipetting trigger to dispense sample into the diluent, followed by three mix cycles. After mixing, 100µL of the diluted sample is automatically aspirated. Move tips to next row and press pipetting trigger to dispense and mix the next dilution. Continue until all dilutions are prepared.
13. To empty the tips of liquid after the final dilution is made, press and appears on the display (or to cancel PURGE, press again). Press and release the pipetting trigger to dispense liquid into an appropriate container.

Mix
Mix is a liquid handling function with repetitive cycles of aspirating and dispensing of the same sample. The function can be used independently of other functions  and is included within the function.
To set-up and run the Mix liquid handling function, follow these steps:
Example: Mix 100µL of solution 5 times

1. Press and release until appears on the display.
   
2. Press or and appears on the display with the current volume setting for mixing. Press or to scroll to the desired setting.

8. Mix 100µL of sample by pressing and releasing the pipetting trigger.
   
9. When appears on the display, remove tips from solution and press the pipetting trigger. The pipette is now ready to perform the next Mix function.
   

Reverse Pipette
Reverse Pipette is a sample transfer function based on an exact dispense volume (TD or “to deliver” pipetting). Sample volume is apirated with a slight overage and the exact amount is dispensed, leaving some liquid in the tip that is purged with the next press of the pipetting trigger. This method of pipetting is commonly used for highly volatile or viscous samples, and/or when working with small microvolumes.
To set-up and run a Reverse Pipette liquid handling function, follow these steps:
Example: Pipette 50µL of sample

1. Press and release until appears on the display.
   
2. Press or and appears on the display with current volume setting. Press or tuntil the desired setting is displayed.

CALIBRATION

Introduction
Each Ovation pipette is factory calibrated to manufacturing specifications and a Certificate of Calibrtation traceable to NIST is enclosed in the unit’s original packaging. The pipette is calibrated at 21.5˚C (±2˚) and relative humidity of 45%-75% using distilled water. It is recommended that calibration be verified every six months or on an as-needed basis, whichever is applicable.
The Ovation pipette can be easily in-lab calibrated ±10% for optimum performance at your operating conditions. In addition, the calibration factor can be pre-determined and set at the appropriate value for a liquid to be dispensed. Changing the calibration factor is quick and easy. Returning the calibration factor to 1.000 will re-set the Ovation pipette to its original factory calibration.
For optimum performance over the entire pipetting range, verify and calibrate the pipette using the maximum volume setting. For a specific liquid at one volume, verify and calibrate at that volume.
With the pipette set to the desired volume, determine the actual volume dispensed*.
Then use Ovation’s calibration software to determine an appropriate calibration factor.
When the calibration factor is changed from the factory setting of 1.000, a “C” appears on the display screen. It is recommended that whenever the calibration factor is changed from the factory setting, that the current factor be recorded in the laboratory’s quality control log.
Determining a New Calibration Factor

1. Perform a verification at the desired volume.
2. Simultaneously press and hold the   buttons (about 3 seconds) until appears on the display. Press and release until CAL appears.
   Note: To interrupt the calibration sequence at any time, depress and release the pipetting trigger. No changes will be saved.
3. Press or and (target) and the pipette’s maximum volume is displayed.
4. Press or to change the volume, but only if calibrating at other than the maximum.
5. Press and (measured) and the maximum volume is displayed.
6. Press or to enter the actual volume dispensed during verification. (See Step 1)
7. Press and (factor) and a new calibration factor is displayed. Record this factor.
8. Press again and (set) appears on the display. After one second, the pipette accepts and stores the new calibration factor. A “C” may now appear on the display.
9. Re-verify volume delivery with this new calibration factor.

* For additional information on calibration verification, go to our documentation library under Support at www.vistalab.com
Entering a Calibration Factor
Ovation allows the user to enter a known calibration factor for a specific liquid or volume, or return to the factory setting.

1. Repeat Step 2 under “Determining a New Calibration Factor. Press until appears on the LCD.
   Note: To interrupt the calibration sequence, press and release the plunger.
   No changes will be saved.
2. Press or , followed by (2 times) to advance to on the display.
   Record this factor.
3. Press or to enter the known calibration factor.
4. Press and (set) then appears on the display while the pipette homes the plungers. The pipette has accepted and stored the new calibration factor.
5. Verify volume delivery at this new factor, or begin to use the pipette.

MAINTENANCE & TROUBLESHOOTING

The Ovation pipette requires minimal maintenance. Always store it in its “standing” position or on the Ovation Pipette Stand (Catalog No. 9058-4003) when not in use.
Cleaning Exterior
The Ovation pipette requires minimal maintenance. Always store it in its “standing” position or on the Ovation Pipette Stand (Catalog No. 9058-4003) when not in use.
Clean outer surfaces as needed with a soft cloth dampened with warm water. To decontaminate outer surfaces, wipe with a 70% aqueous solution of ethanol or isopropranol.
WARNING! Before cleaning or decontaminating the pipette, make sure the power supply is disconnected.
Disinfecting Nozzles
The replaceable nozzle contains an internal aerosol/liquid barrier filter to prevent liquid from being aspirated into the pipette. Additionally, the nozzle filter offers protection to internal parts from routine exposure to hazardous liquids and vapors. If this filter becomes wet, the pipette will not aspirate fluid until a new nozzle is installed or the nozzle filter is replaced.
Wipe the exterior surface of nozzles with disinfectant or a 10% bleach solution.
Care should be taken not to get the barrier filter inside the nozzle wet, as the channel will not aspirate and dispense properly until corrective action is taken.
Nozzle Removal and Installation
If any channels are not aspirating and dispensing properly, it could be caused by (a) poor fitting alternate source tips, (b) a nozzle is loose and needs to be tightened by turning it clockwise, (c) a nozzle or nozzle filter needs to be replaced as liquid has been aspirated into it, or (d) a nozzle seal is worn or torn.
NOTE: Wear gloves when doing this procedure.

1. Push the ejector slide in until it clicks to fully expose the pipette’s nozzles. (For 0.5-20µL models, see note below)
   
2. Remove the affected nozzle(s) by placing the rubber tubing provided onto nozzle, and unscrew it in a counterclockwise direction. If it is suspected that the air tube has been contaminated, gently wipe the end of the air tube with a tissue, then dry it off. To remove a nozzle(s) on 0.5–20 L models, use the nozzle removal tool supplied with
   Replacement Nozzles or the Nozzle Reconditioning Kit.
   
3. Place rubber tubing onto a new nozzle (or nozzle where filter has been replaced), and screw the nozzle onto the pipette in a clockwise direction. Firmly tighten and remove tubing from nozzle.

Replacing a Nozzle Filter

1. Remove the filter inside the nozzle(s) by inserting a straightened paperclip into the small hole in the tip end of the nozzle, and push the filter out through the wide (threaded) opening.
   
2. Pick up a new nozzle filter with tweezers and place it into the wide (threaded) end of the nozzle.
   NOTE: Make sure the narrow end is inserted first
   
3. Use the filter insertion tool to push the filter into position. Press down until the end of the tool makes contact with the inside bottom of the nozzle.
   
4. Tap the nozzle on the counter to remove any loose cellulose material.
   
5. The nozzle is ready for re-installation.

General Battery Information
Note: To extend battery life, the pipette will automatically enter “sleep” mode after 10 minutes of inactivity. Press any key or the pipetting trigger to resume operation.The Ovation pipette’s battery must be recharged for approximately 90 minutes when the pipette is first received, and whenever the battery icon on the LCD is flashing which indicates a low charge. Insert the power plug into recharging port and connect power supply to AC outlet. Recharging a fully drained battery takes approximately 90 minutes. To ensure the pipette always has a full charge, it may be left connected to the power supply indefinitely when not in use.
When a battery is fully discharged or needs to be replaced, settings for all liquid handling functions and the current calibration factor remain stored in the pipette’s internal memory. They are available for use during recharging or following replacement of the battery.
When fully charged, the pipette can perform approximately 600 cycles at full stroke at the highest speed setting. The number of cycles may vary, depending on pipette model, pipetting volume, and speed setting.
To recharge the battery:

1. Insert the power supply pipette plug into the recharging port and connect the power supply to an AC outlet. Recharge a fully drained battery for approximately 90 minutes.

Replacing the Battery

Note: To extend battery life, the pipette will automatically enter “sleep” mode after 10 minutes of inactivity. Press any key or the pipetting trigger to resume operation.
Note: If no battery is installed for an extended time and/or the volume display is blank, when the unit is recharged or the new battery is installed, the volume display will show an “r” value. To return the LCD to its routine display, press once. The LCD will display all character sets and then return to the last liquid handling function.
Note: When the battery is removed, the LCD contrast returns to the factory setting. To adjust the contrast, refer to page 3–9.
The lithium ion battery is a user replaceable part. When the battery requires more frequent charging, is not recharging or holding a charge, it should be replaced. Ordering information is available at www.vistalab.com.
Use of any other battery can cause damage to the pipette and void its warranty.
To replace the battery:

1. Loosen the captive screw on the base of the pipette and gently lower the base away from the body, being careful not to stretch, loosen or disconnect the cable from the circuit board.
   Do not separate the front and back sections of the pipette body at any time.
   Doing so will void the pipette warranty.
2. Note the orientation of the battery. Lift the battery and gently disconnect it.
3. Reconnect a new battery and place the battery in the base of the unit.
4. Carefully fit the base onto the body of the pipette and tighten the captive screw. Be certain that cables and wires do not get pinched. Do not overtighten the screw.
5. Recharge the new battery before using the pipette or plug into power supply.

Troubleshooting

If the Ovation pipette fails to function as expected, review the following.
Symptom: Pipette display is blank
Probable cause:
Battery is drained, connector not tight, crimped or broken connector wire, faulty AC power supply or AC power source, or LCD contrast may need to be adjusted.
Recommended action:
If battery was recently replaced, check connector and wires for crimps or broken wire.
Plug into an AC power supply and AC source. If Ovation display functions normally, then problem is a broken battery wire or the replacement battery is inoperative. Send to VistaLab for repair. See LCD contrast instructions on page 3-9 and adjust if possible.
Symptom: Pipette makes “alert” sound
Probable cause:
Pipetting trigger was pressed before set-up of a liquid handling function was complete or an illegal action was performed (e.g. trying to enter set-up before a liquid handling function was completed).
Recommended action:
Continue setting up function or exit setup. Continue pipette operation until liquid handling function is completed.
Symptom: Aspirating and dispensing is slow
Probable cause:
The pipette speed is set to a low setting
