Non-contact Liquid-Level Volume Detection
The VolumeCheck 50 uses ultrasonic technology to measure the height of the sample meniscus without coming into contact with the sample. The volume of each well of a 96 well plate is returned in 3 minutes. For faster models, consider the VolumeCheck 100 or VolumeCheck 384.
All designed, fabricated, and tested in our Concord, CA facility made from the highest quality materials.

How It Works
The VolumeCheck uses ultrasonic technology to measure the distance between the sensor and the height of the meniscus. It then extrapolates the distance from a calibration table created by the user and outputs the volume. The technology allows for sample measurement of sample volume in a wide variety lab ware.
The VolumeCheck software calibration wizard assists the user in efficiently creating the calibration table, which is based on known volumes of a given sample. Many calibration tables can be stored, making it easy to switch between sample types and different types of labware.
The resolution and accuracy will depend on whether the samples were centrifuged, any dimensional variation in labware consumables, the accuracy of the calibration tables created by the user, and the sample volume in the plates. The VolumeCheck returns a higher resolution with low volume plates vs. higher volume plates (PCR plates vs. 2.2mL deep well plates).
The VolumeCheck exhibits good repeatability, which makes it an appropriate choice for many volume inspection tasks.
