BIOTECHSOLVENT DEGASSING

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 at very high flow rates.

DEGASi PLUS GPC

DEGASi® PLUS GPC is the right choice of degasser if you are working with 100 % organic solvents in your fluidic line. Example of application areas where this degasser is successfully used are GPC (Gel Permeation Chromatography) and Normal Phase Chromatography.

DEGASi® PLUS GPC uses the same 480 µl Systec AF™ degassing membrane as used in DEGASi® Classic. The main difference compared with the DEGASi® Classic is that we use a stented version of the vacuum chamber in the DEGASi® GPC. The stent is a short piece of a stainless steel tube placed inside the ends of the degassing membrane, in order to make the internal ferrule in the bulkhead to get a better grip. This solution makes an even more secure internal connection when working with 100 % organic solvents in the fluidic line.

PRODUCT FEATURES

DEGASi® Compact is available with 2, 4 or 6 degassing channels in a housing with only 167 x 59 mm footprint. This is possible due to the development of a new single stage vacuum pump with a small built in control board and new 285 µl Systec AF™ vacuum chambers.

Closed-loop control with a continuously running vacuum pump gives a very smooth baseline. The speed of the pump is varied to maintain an exact vacuum level inside the vacuum chambers.

The degasser is equipped with built in error detection functionalities. A bi-colour diode on the front panel gives information about the performance. The extremely low internal volume of 285 µl provides very fast priming and start up. Despite the small size of the unit it has an expected life time of more than 6 years.
