VolumeCheck is a benchtop device that connects to a Windows PC. A control program running on the PC manages the VolumeCheck and organizes data collected by the VolumeCheck.
VolumeCheck uses a non-contact ultrasonic sensor to measure the distance from the sensor to the surface of the sample liquid in a tube or well plate. Using a calibration table of distance measurements vs. known volumes, the VolumeCheck can be used to measure unknown sample
volumes in well plates and tubes.
To determine sample volume, a calibration plot of sensor-to-liquid distance and sample volume is
required. Data for this calibration plot is obtained by incrementally dispensing and measuring the
sample volume. The calibration plot data is stored in a calibration file that can be used for future
volume measurements. The calibration file is specific to labware and sample type.
