The series of Biotech Liquid Flow Meters enables easy, continuous, and integrated determination of liquid flow rates. With these devices, flow data is continuously and accurately recorded and stored in a computer application providing full flow control and documentation. The measurement principle of heat dispersion allows for unprecedented time resolution and provides new insights into flow variation and inconsistency. The internal flow cell has a minimal volume and the inline measurement is accomplished without any interference with the liquid or its flow path. Four different models are available for micro flow, analytical HPLC flow, preparative flow, and high volume flow rates. -

The Biotech Solvent Recycler is a completely stand-alone device with an integrated display to show current input and settings, and control keys to easily set its operational parameters. It is typically externally powered via 5V DC, but can also be powered and programmed via a USB connected computer running a terminal software application. The Biotech Solvent Recycler can reduce the mobile phase in isocratic HPLC for up to 90% by redirecting uncontaminated mobile phase into the container. The level of the input signal and setting parameters are displayed on a well-read four-digit LCD display. Valve position and the current display mode are indicated by LEDs placed next to the display. Instrument functions are operated via a membrane keyboard with six keys. Setting of operating parameters and online device activity tracking can also be performed from a PC using any terminal application. Its analog input accepts unipolar and bipolar signals in ranges of ± 1V or ±100 mV alternatively. Analog-to-digital converter provides data for further processing in embedded microcontroller. TTL (contact closure) input is used for the auto-zero function. This model has a PEEK solvent flow path, but the Biotech Solvent Recycler is also available with wetted material in PTFE. -

The DEGASi® BioCompact degasser is designed to minimize laboratory footprint while providing adequate degasification properties for several different aqueous and organic liquids in analytical instrumentation at an attractive price. This degasser is available with only one type of degassing chamber, but this is fully biocompatible and designed for many applications with flow rates up to 2 mL/min. This degasser construction is suitable for typical reversed phase HPLC and ion chromatography applications, while also being compatible with straight phase chromatography and gel-permeation chromatography (GPC) that employ hexane and similar organic solvents. The port design is 1/4-28 Flat-Bottom for connection of tubing with OD ranging from 1/16” to 1/8”. See Solvent Compatibility Chart » -
The new DEGASi® FlatFilm degasser redefines the capabilities of inline degassers. This engineering marvel delivers double the degassing performance per unit volume, at ten times lower flow resistance, while also reducing evaporative solvent loss, relative to traditional tubular degasser designs. In addition, this new inline degasser provides an extremely silent operation with about thirty percent longer life expectancy compared to traditional constructions. It also offers a reduced environmental footprint by requiring only one tenth the amount of perfluoroalkylated (PFAS) polymers within the degassing membrane. The DEGASi® FlatFilm stand-alone inline degasser is suitable for a wide range of analytical and semi-preparative applications involving anything from biocompatible requirements to demanding organic solvent compatibility including hexane. The slim housing, recognized from the popular DEGASi® Plus series, occupies a small bench space (230 x 56 x 107 mm). The nominal flow rate is 6 mL/min per channel, and this degasser is available with 1-6 degassing channels each with a flow path of 500 µL. The port design is 1/4-28 Flat-Bottom for connection of tubing with OD ranging from 1/16” to 1/8”. See Solvent Compatibility Chart » -
Suitable for high flow applications like chemical analyses, biotechnology or sensitive processes on the manufacturing side. DEGASi® HIGH FLOW 1000 works with real high flow rates and ultra-high degassing efficiency. With water-based solutions it removes dissolved gases at flow rates up to 1000 ml/min.

The DEGASi® Integration Classic degasser is designed for most applications in analytical instrumentation and liquid chromatography, including typical reversed phase HPLC and ion chromatography applications with flow rates up to 3 mL/min. The port design is 1/4-28 Flat-Bottom for connection of tubing with OD ranging from 1/16” to 1/8”. This degasser is equipped with 1-5 chambers with biocompatible flow path of 480 μL for aqueous-organic liquids but is not compatible with hexane and similar organic solvents. As with all DEGASi® Integration degassers, there is an output signal for the vacuum level, and you can expect very silent and trouble-free operation for many years. It is easy to exchange solvents in the degasser thanks to the low swept volume and efficient design of each channel. The internal patented closed-loop vacuum control assures ultra-stable degassing performance that minimize noise in your high-precision system. The degasser comes with advanced leak and error detection functions and three indicator LEDs to show current status. The housing occupies a reduced bench space (261 x 70 x 125 mm) and is easy to access for replacement of parts. The degasser is fully compatible with CE and RoHS directives.
