SRI - Model S 8515 -Vacuum Degasser

High Efficiency

The highly 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 the capillary to reduce the dead volume of the system considerably.

2 Operation Modes

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 Degasser a membrane for creating the vacuum. This membrane is made of a specific Teflon material specifically designed for fast movements. We offer a 5-year warranty on the lifetime of this membrane.

Multi-Channel

The S 8515 Vacuum Degasser is available in 1-Channel, 2-Channel, 3-Channel, or 4-Channel versions. Each solvent channel can be used for a different solvent. Several channels can be used in series to increase efficiency even more.

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 the 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.
