February 16, 2007 - Designed for collection of flow rate data for HPLC calibration, qualification, and validation (IQ/OQ/PQ) in FDA-regulated laboratories, FlowCal 5000 has RS232 interface and wetted parts made of PTFE, PEEK, DAI-EL, PERFLUOR, or Pyrex glass, making it inert to all common HPLC mobile phases. Digital tool is UKAS-traceable and measures flows to 1 l/min, with linearity from 0.05-25.00 ml/min. Flow rate, measured by volume, is independent of liquid type up to 10 cps viscosity.

HPLC Liquid Flow Meter Simplifies Calibration and IQ OQ PQ Validation

The FlowCal 5000 Digital Liquid Flow Meter is compact, robust, and accurate at low flow rates making it indispensable for IQ/OQ/PQ validation and calibration of HPLC systems.

SOUTH ORANGE, NJ - February 11, 2007 - Tovatech LLC announces a new laboratory tool: the FlowCal 5000 Digital Liquid Flow Meter for calibration of HPLC system flow rates. The FlowCal 5000 Liquid Flow Meter is an indispensable tool for chemists, metrologists, and validation specialists responsible for HPLC calibration and qualification. The FlowCal 5000 is accurate, durable, traceable and certified. It's designed for HPLC calibration and validation and is significantly more convenient and reliable than gravimetric or volumetric flow determination. The FlowCal 5000 substantially reduces HPLC pump troubleshooting time. Leaking piston seals or malfunctioning check valves are easily diagnosed.

Miniaturized to just one third the size and weight of other models, the FlowCal 5000 is the most compact and easy to use unit available. The flow meter measures flows accurately to 1l/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.

No user calibration is required; the unit is supplied gravimetrically calibrated at 1.0 (+/-1.0%) ml/min. Calibration at multiple points is available. A UKAS traceable calibration certificate is supplied with every flow meter (UKAS is the UK equivalent of NIST). All wetted parts are made of PTFE, PEEK, DAI-EL, PERFLUOR, or Pyrex glass making the liquid flow meter inert to all common HPLC mobile phases. There are no wetted metallic parts.

The FlowCal 5000 simplifies 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). A new miniature thermal printer is available. The printer will print all readings and error messages output from the liquid flow meter. The printer is supplied with rechargeable batteries. The FlowCal 5000 is supplied with a carrying case with foam inserts, a cleaning kit, and a universal mounting kit.

In addition to liquid flow meters, Tovatech supplies the full Elma, Elmasonic ultrasonic cleaner line - from bench top units for laboratory use to large industrial cleaning equipment. In addition Tovatech carries a moisture analyzer line, and Cecil Instruments' HPLC and UV Vis Spectrophotometer lines.

RE: request for fuel flow meter with printer

Dear Narendra,

The FlowCal 5000 cannot be used for your application. You are looking for an in-line mass flow meter. That is an entirely different type of flow meter.

Best Regards,
