SKU: IC 9575 Category:

The KNAUER Online Degasser is a 2-channel for semi-preparative flow rates up to 50 ml/min. The degassing membrane is an innovative Teflon AF fluoropolymer which is more than 200x more gas permeable than regular Teflon and has excellent physical and chemical stability characteristics. Its high efficiency also allows for reduced internal chamber volumes– less than 7.7 ml per channel. For isocratic HPLC applications the 2 chambers of the semi-prep degasser can be connected in series for maximum degassing efficiency. For gradient applications, up to 2 eluents can be degassed simultaneously. For special applications, one degasser can also be used for multiple HPLC systems. The low dead volume makes reconditioning fast and minimizes solvent waste.
Extremely low chamber volumes.

Broad chemical compatibility is perfect for use in general HPLC applications
Zero hysteresis even at higher flow rates
No need to replace check valves or other parts even when under continuous operation
Prevents air bubble spikes in the chromatogram
Minimizes retention time fluctuations
Minimizes gradient reproducibility problems
Minimizes unwanted formation of chromophores which can disturb UV detection
Minimizes unwanted oxidation or reduction which can disturb electrochemical detection
Minimizes fluorescence quenching
