Liquid flow meter for HPLC calibration

US-based Laboratory equipment distributor Tovatech LLC has launched a liquid flow meter designed for the calibration of HPLC (High Performance Liquid Chromatography) system flow rates. The FlowCal 5000 Liquid Flow Meter is designed for chemists, metrologists, and validation specialists responsible for HPLC calibration and qualification and is significantly more convenient and reliable than gravimetric or volumetric flow determination, Tovatech says. It is designed to simplify the collection of flow rate data for HPLC calibration, qualification and validation (IQ/OQ/PQ) in FDA-regulated laboratories. Flow rate data can be output to any device with an RS232 interface (eg. printer, terminal or PC) and a new miniature thermal printer is available.

The FlowCal 5000 substantially reduces HPLC pump troubleshooting time, because leaking piston seals or malfunctioning check valves are easily diagnosed. It is miniaturized to just one third the size and weight of other models, and can measures flows accurately to 1µl/minute with guaranteed linearity from 0.05 to 25.00 ml/min. Flow rate is measured by volume and is independent of the liquid type up to a viscosity of 10 centipoise.
