Repair & Warranty

Register your pipette

Repair service can be added to any of our Calibration services for a flat fee (determined by pipette model) that covers labor, handling and basic replacement parts (nozzles, filters, keypads, etc).  Any required parts not covered (PCB’s, motors, piston assemblies, etc) will be added to the overall service charge.  We will contact customers of any added charges and only move forward with repairs once approval is received.

All repairs are done using Original Manufacturer’s parts. Other calibration labs may use generic parts which can affect performance and require more frequent maintenance. VistaLab repair service also covers replacement of uncommon wear parts as standard procedure. Customers can request repair reports by contacting Technical Support.


Warranty on all services performed on MLA and Ovation pipettes 90 days from the date of service:

  • Must provide VistaLab Order # and Pipettes’ 6-digit Serial Number
  • For calibration discrepancies, pipettes can be sent back (at customers expense) inspected and have calibration verified.
  • Installed replacement parts warrantied for 1 year from date of service
  • Warranty voided for improper handling, unauthorized modification or use with corrosive chemicals

Contact Technical Support for instructions to send in for Warranty services

How often should I calibrate my pipettes?

As the manufacturer of MLA and Ovation pipettes, VistaLab recommends performing routine maintenance and calibration verification on pipettes at least once every 6-12 months (depending on how often they are used and what they are used with). 

Required maintenance and calibration intervals are determined by your labs’ internal quality/ regulatory system. Customers should always first consult with their quality department.

Maintenance and Calibration Frequency

What is the difference between As-Found and As-Left data?

As-Found – Pipette performance is tested before any parts are replaced or any calibration adjustments are made (Verification)

As-Left – Pipette performance is tested after seals and O-rings are replaced and calibration adjustments are made (Calibration)

What does Preventative Maintenance include?

Preventative Maintenance is the cleaning and lubricating of plunger and pistons followed by the replacement of normal ‘wear’ parts- including, but not limited to, O-rings, seals, nozzles and filters. 

Can I use another brand of pipette tips when calibrating?

While there may be other brands of tips that fit with Ovation and MLA pipettes, they are factory calibrated with VistaLab brand tips. Different brand tips have different dimensions and geometries, so performance will vary from tip to tip.  If pipettes are used with another brand tips, customer should adjust pipettes’ calibration according to the procedure described in the models’ corresponding Operators Manual.

Can I adjust my pipettes' calibration in my lab?

Yes. MLA and Ovation pipettes can be adjusted in the lab to linearly increase or decrease volume delivery to adapt to different laboratory testing conditions. Refer to Performance Verification documents for MLA or Ovation. We recommend replacing piston seals and lubricating before any calibration adjustments are made.

What brands of pipettes do you calibrate?

We only calibrate VistaLab MLA and Ovation pipettes..

What is the turnaround time for Calibration?

Typically 2-3 days for MLA pipettes and 5-7 days for Ovation pipettes (not including shipping time). 

What volume do I use to calibrate my pipette?

MLA and Ovation pipettes leave the factory calibrated at their published specs, or 100%, 50% and 10% of maximum value. For frequently used volumes that are not published, it is the discretion of the customer to adjust for that volume. Refer to pipette Specifications.


Ovation pipettes are very easy to use. My hands never get tired or hurt when I use them. Their ergonomics distinguish them from all other pipettes. I have arthritis in my hands and these pipettes never stress my joints. Other pipettes make me reach uncomfortably or need too much pressure to release the tip. I absolutely love Ovation pipettes, would not use anything else!

In our lab, we all experience shoulder and wrist strains and overall tightness in the back and shoulders from using axial pipettes. With the Ovation, though, you don't have to hold it up very high to clear the test tubes. And the tips fit so well, they're easy to put on and easy to eject.

I wish the Ovation had been available 10 years ago. I'm convinced I would have never developed Carpal Tunnel Syndrome from pipetting. The Ovation uses nice, gentle motions without force. All the stresses and strains of the standard pipette are totally gone.

I was having a lot of pain in my wrist. I started using Ovation, and in less than a week, I stopped having problems!
