S 7515 Vacuum Degasser The Sykam S 7515 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 OEM Sykam offers this instrument as an OEM product to any interested party, even for small numbers. Besides the complete instrument Sykam also offers the vacuum pump and vacuum chambers as OEM modules. 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. 2 Operation Modes The S 7515 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 7515 vacuum pump uses a membrane for creating the vacuum. This membrane is made of a specific Teflon material specifically designed for fast movements. Sykam offers a 5-year warranty on the lifetime of this membrane. Multi-Channel The S 7515 Vacuum Degasser is available as 1-Channel, 2-Channel, 3-Channel, or 4-Channel version. Each solvent channel can used for a different solvent or several channels can be used in series to increase the efficiency even more.

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.
