The DEGASi® family of stand-alone inline degassers ensure efficient removal of dissolved gases in flowing liquids under a wide variety of conditions. Regardless of whether you require a flow path with full biocompatibility, or durable to withstand the most aggressive organic solvents, there is always a DEGASi® model that suits your needs for an efficient and robust degasification process. With different models designed for flow rates from a few microliters per minute up to one litre per minute, the DEGASi® family is by far the most complete product range of degassers in the world.

Core degasser designs

The DEGASi® family of stand-alone inline degassers are available in a couple of core designs with different capabilities and features. The core designs are then configured with degassing channels for different solvents and flow rate ranges. All degassers from Biotech Fluidics rely on long-lifetime vacuum pump technology with closed-loop vacuum control plus advanced leak and error detection functions, to provide ultra-stable performance in every degassing situation.

DEGASi® Plus series
The new global standard for slim and silent stand-alone vacuum degassers with flexible design. Can be configured with 1-6 channels.

DEGASi® Integration series
Unique output allows your system control software to continuously monitor the degasser vacuum level and log it with your other process parameters. Can be configured with 1-5 channels.

DEGASi® Preparative series
Outstandingly powerful models to accomplish degassing of aqueous-organic liquids at high liquid flow rates. Can be configured with 1, 2, or 4 channels depending on model.

DEGASi® BioCompact
The smallest stand-alone inline vacuum degasser with a fixed metal-free flow path. Can be configured with 1-6 channels.

Channels for different solvents and flow rate ranges

The DEGASi® core designs are configured with one or several degassing channels for a particular solvent type and flow rate range, thereby creating complete degassers of various models for specific requirements. For easy navigation, these channels have been grouped into four categories, differentiated by their flow rate ranges.

For typical analytical systems

DEGASi® Classic
The first choice for most applications in analytical instrumentation and liquid chromatography, including typical reversed phase and ion chromatography applications with flow rates up to 3 mL/min. Biocompatible flow path of 480 μL. Not for use with hexane. Available in the DEGASi® Plus and DEGASi® Integration series.

DEGASi® GPC
Designed for straight phase chromatography applications with flow rates up to 3 mL/min. With the stainless-steel stented flow path of 480 μL this degasser is intended for use with all common organic solvents including alkanes like hexane. Available in the DEGASi® Plus and DEGASi® Integration series.

DEGASi® HFIP
Especially designed for hexafluoroisopropanol (HFIP) often used in size-exclusion SEC and GPC applications. Equipped with a unique SS stented flow path of 480 μL for flow rates up to 3 mL/min. Also suitable for alkanes including hexane. Only available in the DEGASi® Integration series.

For systems with higher flow rates

DEGASi® Semi-Prep
