DEGASi® Stand Alone Degassers

Biotech® DEGASi Degassers line up

A BIOTECH DEGASi FOR EVERY APPLICATION!


No troubles with Bubbles

The Biotech DEGASi series of online degassers ensure efficient degasification of flowing liquids under a variety of conditions. Designed for different solvents and a wide range of flow rates, there is always a model that suits your needs for an efficient degassing process. Biotech have set a new world standard for vacuum degassers with the introduction of the DEGASi PLUS series, and with the outstandingly powerful DEGASi PREP+ model, degasification of aqueous-organic solvents can now be accomplished also at very high flow rates. If in doubt what vacuum degassing model would best suit your conditions and demands, please contact Biotech for guidance and technical support.


Typical Degassers for analytical systems

DEGASi PLUS Classic is the first choice for most applications in analytical instrumentation and liquid chromatography. This state-of-the-art stand-alone degasser will provide you with trouble-free vacuum degassing day after day with perfect degasification up to 3 ml/min.
DEGASi PLUS GPC is the best vacuum degasser model when you are working with 100% organic solvents in your fluidic line. Example application areas where this degasser excels is gel permeation chromatography (GPC) and normal phase chromatography.
DEGASi COMPACT is a stand-alone degasser model which combine cutting-edge technology with a very small footprint at an affordable cost. Efficient degasification up to 2 ml/min can be expected from this model.


Small Volume Degasification

The DEGASi PLUS MICRO is the perfect choice when you are working with very small flow rates and want to minimize volumes inside your system. With only 100 μl internal volume, this degasser model will still accomplish excellent degasification up to about 0.5 ml/min.


High Flowrate vacuum degassing

When working with higher flow rates, up to 6 ml/min, we recommend the DEGASi PLUS SEMI-PREP vaccum degasser. This model can be used up to 10 ml/min but with a bit lower degassing efficiency. The DEGASi PREP is built for even higher flow rates and can remove dissolved gases at flow rates up to 50 ml/min per channel while still offering short startup times thanks to the low internal volume.
DEGASi PREP+ is a unique vacuum degasser, built for the most demanding applications. It can handle higher flow rates of mixed aqueous-organic solvents than any other degasser available today. This degassing system removes dissolved gases at flow rates up to 75 ml/min per channel and the channels can be connected in series ta handle even higher flow rates.
DEGASi HIGH FLOW provides an efficient degassing process for liquid flow rates up to 500 ml/min. Being based on silicone-membrane technology, this degasser is many designed for aqueous liquids.
