Liquid Handling

MIDSCI has a full line of liquid handling products including laboratory pipettes, pipette tips, pipettors, reagent reservoirs, aspiration systems, and pipette controllers.

Some liquid handling products are known to have safety issues and others are prone to errors that lead to poor results. 
  
Our liquid handling products keep in mind the basics, like price and quality, but also go one step further to solve or pre-empt these and other issues researchers (and even the planet) may face. 
  
For instance, the aspiration systems we stock are known for performance but also for safety. Our pipettor calibration service ensures reproducible results. We carry unbreakable transfer pipettes that avoid glass hazards. And we even have eco-friendly reagent reservoirs!

CheckIT Pipettor Accuracy Tester

  • Daily confirmation - Validate the accuracy of your liquid handling robots or multi-channel pipettes daily or weekly.
  • Periodic measurement - Quickly and easily measure the accuracy of your robot or multi-channel pipette.
  • Alleviate concerns - Concerned that a robot or a pipette was misused or needs calibration? Just Checkit.


Checkit Go disposable cartridge instantly checks accuracy of liquid handlers and multi-channel pipettes

The Checkit Go is an easy-to-use, stand-alone, disposable cartridge that allows you to check the accuracy of your liquid handling robot or multi-channel pipette in just seconds. No additional equipment is required. The Checkit Go is interchangeable with well plates, so it works with all robots that handle 96 well plates. Compatible with all makes of multi-channel or electronic pipettes.


Fast and Convenient - verify up to 8 channels in seconds

This surprisingly simple device measures the dispensed volumes of up to 8 channels simultaneously. It is the size of a well plate, so you can use it in your robot, or on a lab bench, or anywhere. You're done in under 10 seconds. That means no more trying to read a tiny droplet's weight on a high-precision balance, and repeat for 7 more channels.


Accurate - directly measures liquid volume

The Checkit Go directly measures the volume of the liquid dispensed, not an indirect measurement of the weight or the color change of a liquid. In addition to being so quick and easy to use, the Checkit Go limits evaporation to negligible levels because the dispensed droplets are mostly encased in glass tubes within seconds. Measurements are guaranteed to be accurate to within 2% and typically better than 1%.


Easy to Use - no training required

Just aspirate the dye that is included. Dispense the dye into the wells on the flip tab of the cartridge. Flip the tab. Or let the robot flip the tab. Then watch the dye travel up the 8 channels, simultaneously. Don't blink or you'll miss the fun. And compare the level of the dye against the graduations. It's that easy!

No more trying to read a tiny droplet's weight on a high-precision balance. No training required. No need to learn to use expensive colorimetric systems. And you can record the measurement with a simple photo.


Cost-effective - no capital investment

The Checkit Go is a fraction of the cost of unnecessary calibration or experiments gone bad due to pipetting errors. It is a low cost disposable cartridge that works on its own. It shows the measured volume directly on the cartridge. Just compare the level of dye against the graduations, without any expensive balances or spectrophotometric equipment.


Reliable and Proven

The Checkit Go provides dependable and repeatable measurements across different automated liquid handlers. It is based on the same technology as the Checkit Pro which has been used throughout the world since 2017.
