BIOTECH LIQUIDFLOW METER

Measures continuous flow rates without
interference in your fluidic systems

Biotech Introduces a Unique PocketSized High Resolution Liquid Flow Meter
HPLC Flow Meter AB-40010
The new Biotech Liquid Flow Meter can continuously
and accurately determine in-line flow rates in any modeof liquid chromatography without system interference.
It is compatible with all HPLC and GPC solvents,
conveniently sized and powers itself from a USB
connection.
It is very easy to use, small enough to fit in your hand orlab coat pocket – weighing less than your cell phone!
The Biotech Liquid Flow Meter comes pre-calibrated
and can be connected in-line in any orientation tocontinuously measure flow rates.

Improved Results
Supplied digitally calibrated, the AB-40010 delivers high-precision and accuracy
across a wide measurement range.
Validate your system and get pump performance diagnostics at the same time!
Ease of Use
Specially designed app for easy interaction.
• 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!
Reliable Trouble-free Operation
The ultra-reliable AB-40010 is suitable for virtually any flow application andcompatible with all standard GPC/HPLC solvents.
Application Areas• Chromatography – validation & diagnostic purpose• Peristaltic pump monitoring• Flow chemistry• Process flow applications

Technical Data
The Biotech Liquid Flow Meter is specifically designed for continuous measurement of flowrate without interference in fluidic systems. Being compatible with most solvents, a wide
pH range, and pressures up to 3 MPa (435 psi), it is the perfect tool for high-precision
measurement of flow rates ranging from 1-80uL/min up to 650 mL/min.
Via its USB interface and modern PC application, data is recorded as time series, which is helpfulwhen troubleshooting pumps, check valves or other malfunctioning components in liquid
chromatography equipment.
The app allows the user to select the integration interval for average flow rate or pump performance.
Current flow rate is displayed on the Flow Meter’s integral high-resolution OLED display while recording and storing the measured flow rates. Extraordinary high resolution and wide dynamic range makethe Biotech Liquid Flow Meter the perfect flow monitoring tool for the most demanding fluidic systems.
