Checkit Go – Validate Pipetting Accuracy of Robotic Liquid Handlers

Checkit® Go - Verify accuracy of pipetting in seconds

Checkit Go being used with robot liquid handler to precisely measure dispensed volumes.

Engineered for Liquid Handling Robots and Multi-Channel Pipettes. Breakthrough technology gets the job done in seconds!

Checkit Go cartridge instantly checks pipetting accuracy of robotic liquid handlers

The Checkit Go is an easy-to-use, stand-alone, disposable cartridge. It enables you to validate or measure the pipetting 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 of your samples

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%. (Our new 2 µL model is guaranteed to 3% accuracy.) Every cartridge is individually inspected by NIST traceable calibrated instrumentation and Certificates of Accuracy are available for every Checkit Go cartridge (except for 2 µL models at this time). The Checkits can measure dispensed volumes of a spectrum of aqueous samples, including 10% solutions of DMSO, glycerol and ethanol, and other aqueous samples such as serum and plasma. This eliminates sources of error due to differences in viscosity or surface tension between your samples and concentrated dye or distilled water. Just reconstitute our red dye pellet in your test liquid. Why spend $30K on equipment that could introduce errors?

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

These easy to use cartridges are 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.

Document your validation tests.

First you capture an image of the Checkit Go, which is done similarly to remotely depositing a check. Next the Checkit Recorder analyzes the image, providing accurate results. The data can be viewed on the device or downloaded along with images and a report of dispensed volume averages and standard deviations from run to run and from channel to channel. If you set pass fail criteria, it reports the passes and fails, too. You can set up templates with memorized values such as the brand, model, and serial number of the robots, the software, pipette head and tips, and pass fail criteria by volume or percentage. You can also set up users with passwords.

Checkit Go Models & Accessories

Each size of Checkit Go can test from 50% of the nominal volume up to the nominal volume. For example, the 50 ml CheckIt can test from 25 – 50 ml volume and the 2 ml Checkit can test from 1 – 2 ml. The non-toxic dye pellets are used to visualize the liquid for more accurate readings.
