MEASURING WITHOUT
INTERFERENCE IN YOUR FLUIDIC SYSTEMS
Biotech is proud to introduce a new Flow Meter series which enables continuous measurement of flow rate, without interference in fluidic systems.
A modern PC based App allows continuous recording and storage of the measured flow rates.
Improved Results
. Supplied digitally calibrated with a certificate of conformity, our range of flow meters deliver high-precision and accuracy across a wide measurement range.
. Monitor your fluidic system and get pump performance diagnostics at the same time!

Ease of use
. Use the specially designed app for easy interaction and control.
. Save the data to your system
. Set the integration time - from continuous reading up to 10 seconds
. Choose between 5 different pre-calibrated solvents or add your own
. 4 different versions for flow rates ranging from a few nl/min up to 650ml/min

Reliable Trouble-free Operation
. Our ultra-reliable flow meters are suitable for virtually any flow application.
. The Micro- and HPLC-flow versions are compatible with all standard GPC/HPLC solvents.

Application Areas
. Chromatography – validation & diagnostic purpose
. Peristaltic pump monitoring
. Flow chemistry
. Process flow applications
. And more…

The Biotech Liquid Flow Meters are specifically designed for continuous measurement of flow rates. Compatible with a wide range of solvents/pH and pressures up to 3 MPa (435 psi), it is the perfect tool for high-precision measurement of flow rates ranging from 1-80µl/min up to 650 mL/min.

With the included app you will be able to take full control of your fluidic system.

At Biotech Fluidics, our aim is to help you make your analytical work more effective and reliable. For more than 15 years we have developed and delivered innovative laboratory products to leading laboratories, instrument manufacturers and distributors across the world. We specialize in chromatography instruments, detectors and consumables plus finding solutions to issues with gases and bubbles in fluidic systems. By using our advanced degassers, labs can optimize the performance of their analytical instruments and chromatographic equipment. Our degassing solutions save the industry both time and money by avoiding production disruptions caused by bubbles in the fluidic lines. To support long-term relationships with our customers, it is important for us to take care of the aftermarket effectively. We have therefore built an organization of service and support. In addition, we offer fast delivery of spare parts directly from the company’s stock.
