Legacy DEGASi® Classic

Discontinued old degasser model

Information below for reference only

DEGASi® Classic was the first choice for most applications in analytical instrumentation and chromatography. This stand-alone degasser provided you with trouble free and efficient degassing day after day.


With the highly permeable Systec™ AF membrane an internal degasser chamber volume of only 480 µl is sufficient to give you excellent degassing efficiency up to flow rates of approximately 3 ml/min. The time the liquid spends inside the vacuum chamber is correlated to the degassing efficiency, so with higher flow rate the degassing efficiency will be lowered. In many cases the 480 µl vacuum chamber can be used at 5 ml/min with sufficient degassing.
