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
- Validate the accuracy of your liquid handling robots or multi-channel pipettes daily or weekly.
- Quickly and easily measure the accuracy of your robot or multi-channel pipette.
- Concerned that a robot or a pipette was misused or needs calibration? Just Checkit.
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.
This 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. 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 seven more channels.
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, the Checkit Go limits evaporation to negligible levels because the dispensed droplets are encased in glass tubes within seconds. Measurements are guaranteed to be accurate to within 2% and typically better than 1%.
Easy to Use
Just aspirate the included dye. 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. Finally, compare the level of the dye against the graduations. You can record the measurement with a simple photo.
The disposable cartridge shows the measured volume directly on the cartridge. Just compare the level of dye against the graduations without any expensive balances or spectrophotometric equipment.
Labnet BioPette™ A Pipettor
These precision variable volume pipettors are designed for exceptional
comfort and accuracy. Lightweight and well balanced, they fit comfortably
in either the right or left hand with the large digital display visible to
the user. Chemically resistant, maintenance-free seals and finely polished
pistons provide unsurpassed accuracy sample after sample. The continuously
adjustable, digital micrometer is slightly recessed to prevent
unintentional change and is protected from the effects of thermal expansion
by the insulated body of the pipettor. For convenience, volume can also be
adjusted by turning the push-button. Ergonomically positioned, the tip
ejector reduces fatigue during prolonged use.
