Ovation® ali-Q™
Aliquoting Pipet Controller for repeat pipetting like never before!

Repeat pipetting with your serological pipets!

Use ali-Q for serological pipetting like you’re used to…
PLUS repeat pipetting like never before!
No special costly tips necessary!
  • One-touch repeat pipetting for better accuracy and repeatability.
  • No need to watch the lines on the pipet for multidispensing.
  • Ideal for cell culture.

Now also available in Low aliquoting Speed (LS) version, ~50% lower force, suitable for working with more sensitive cell lines. Select ali-Q LS when you need gentler multidispensing.


A time saver and easy to use. Increase your productivity!

Features that set ali-Q™ apart from all other pipet controllers


  • Highly accurate and precise multidispensing without the need to “eyeball” the meniscus
  • Push one button to aliquot
  • Aliquot any volume up to 5 mL
  • Compatible with all brands and sizes of serological pipets; optimal performance when using Wobble-not pipets
  • Intelligent measuring system = real-time corrections for varying environmental conditions- No adjustment necessary!
  • Accuracy and precision maintained at any dispense angle for more comfortable body positions, especially beneficial in the hood
  • Ergonomic shape design for optimal grip comfort
  • Self-standing, like all Ovation pipettes!


How is ali-Q different than any other pipet controller?

What sets ali-Q apart from every other standard pipet controller is its revolutionary aliquoting technology.

  1. Simply turn the aliquot volume set dial to the volume you wish to repetitively dispense.
  2. Then, aspirate as much volume as you will need to dispense the full number of aliquots. (Ex: You need to dispense 10 x 1 mL aliquots, then aspirate at least 10 mL)
  3. Finally, press and hold the purple aliquot button to dispense each aliquot.

Eliminate time-consuming and inconsistent meniscus eyeballing! Let the ali-Q‘s state of the art intelligent measuring system do all the work for you!

NOTE: ali-Q can also be used the same way as any other standard pipet controller!

What volumes can I aliquot?

The ali-Q “Original” can be set to accurately dispense aliquots up to 5 mL using the aliquot volume set dial.

The ali-Q “LS” lower-speed model can be set to accurately multidispense up to 3 mL using the aliquot volume set dial.

The number of aliquots that can be dispensed is only limited by the size of the serological pipet used with ali-Q.



How many aliquots can I dispense?

The number of aliquots that ali-Q can dispense in one cycle is only limited by the volume capacity of the serological pipet used!



What are the accuracy and precision performance specs?

When using ali-Q as a standard pipet controller, the accuracy and precision (CV%) is determined by the graduations on the serological pipet used, which are typically 1-2%, as well as the user’s ability to consistently eyeball the meniscus and control the liquid dispense.

When using ali-Q as an aliquoting pipet controller,  accuracy and precision (CV%) specifications are as follows:

With Wobble-not serological pipet (any size)
2% accuracy and 1% CV @ 5.0 mL (Original) or @ 3.0 mL (LS)
2% accuracy and 2% CV @ 0.5 mL (Original) or @ 0.3 mL (LS)

With any other brand serological pipet (any size)
3% accuracy and 2% CV @ 5.0 mL (Original) or @ 3.0 mL (LS)
4% accuracy and 3% CV @ 0.5 mL (Original) or @ 0.3 mL (LS)

NOTE: ali-Q is factory calibrated with Wobble-not serological pipets for optimal accuracy and precision.

What effect does varying temperature, humidity and pressure have on the performance?


Whether you are on a mountain top, desert plains or a tropical island, the ali-Q‘s state of the art smart measuring technology will compensate and correct for extreme environmental conditions!

Thanks to the numerous high resolution sensors, gauges and valves in ali-Q‘s intelligent measuring system, ali-Q can automatically make adjustments to dispensed aliquot volumes in real-time to compensate for varying environmental conditions!

No need for in- lab calibration adjustments or correction factors!

What effect does varying dispense angles have on the performance?

Again, NEGLIGIBLE! (See above)

Whether you’re working in a hood, or on an open bench top, you can be confident in the accuracy and precision performance. The ali-Q has an internal accelerometer that makes automatic real-time adjustments to aliquot dispensing at varying angles.

No need for awkward and uncomfortable body positioning and contortion to maintain a 90 degree dispense angle!

Why does my ali-Q randomly make noises when I'm not using it?

You may have noticed your ali-Q is very sensitive to movement and vibrations. Even the slightest action can cause it to ‘wake-up’ from sleep mode.
The ali-Q will automatically put itself into sleep mode after being motionless and unused for 30 seconds. The internal sensors in the ali-Q will automatically wake it from sleep mode when it is picked up or moved. These sensors are very sensitive to movement, so even vibration from dropping a book on the desk or somebody bumping into the desk can cause it to wake up. When it wakes up, you will hear the motor activate for 1-2 secs while ali-Q gathers information on its environment.


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!

I manually pipette many samples a day. That caused a lot of pressure on my shoulder and elbow, and especially my thumb when ejecting tips. I developed elbow pain and numbness that was diagnosed as carpal tunnel syndrome and required surgery. Now I'm using an Ovation and haven't had any further problems.

Dawn Cherry, Medical Laboratory Technologist

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 used to have tennis elbow and I don't even play tennis. It was from pipetting. I had to stop for a couple of months and start physical therapy. Now I also use the Ovation. I just love it! It's so comfortable and my arm is better.

Jody Bowen, Sr. Technical Associate, University of Rochester

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.

Karen Sklowoski, Medical Technologist, Marymount South Lab Copy

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