S 8515 vacuum degasser The S 8515 vacuum degasser is an online degasser system with high efficiency. Dissolved gases are removed from the solvents by applying vacuum to a semi- permeable membrane. High efficiency The high efficient Teflon-AF® capillary has a much higher efficiency than a normal Teflon capillary of similar size. This allows the usage of a smaller length of capillary to reduce the dead volume of the system considerably. Operation modes Figure: S 8515 vacuum degasser The S 8515 vacuum degasser can be run either with constant speed or in hysteresis mode, which switches the vacuum pump on or off. 5-Year membrane warranty The S 8515 vacuum pump uses a membrane for creating the vacuum. This membrane is made of a specific Teflon material specifically designed for fast movements. Schambeck SFD GmbH offers a 5-year warranty on the lifetime of this membrane. Multi - channel The S 8515 vacuum degasser is available as 1-channel, 2-channel, 3-channel or 4-channel version and also in a PEEK—metal free version. Each solvent channel can be used for a different solvent or several channels can be used in series to increase the efficiency even more.

S 8515 vacuum degasser Working principle The solvent flows through a short length of Teflon AF® capillary inside a sealed chamber. This chamber (vacuum chamber) is completely sealed to the environment and vacuum is applied with a pump. Due to this vacuum any dissolved gases in the solvent running through the inner capillary are removed through its semi-permeable membrane wall. The high efficiency of the Teflon AF® material allows the usage of a very short length of capillary inside the vacuum chamber.
