Operation Principle of the Online-Degasser
In a vacuum chamber, the solvent to be degassed is distributed into several, parallel arranged, semi-permeable membrane chambers.
When a high vacuum (more than -850 mbar) is applied, only the in the liquid dissolved gases are diffusing through the thin membrane.
With a total solvent volume of 8 ml per degassing channel, the Degasser S 7510 achieves an extremely low remaining gas concentration of 0.5 to 5 ppm oxygen, depending on the degasser's flow rate (0 to 10 ml/min.).

With a given flow rate; the degassing quality can be further increased by coupling two or several membrane channels. The digital display of the actual vacuum in millibar makes the degasser S 7510 the first vacuum degasser on the market which functions can be checked and documented at any time.
The degasser S 7510 is availabel with and without digital display. All functions are the same for both degasser S 7510.
