Chromatography degasser 0.2 µm | IFD

Whatman in-line filter/degassers (IFD) connect directly into an HPLC line to simultaneously filter and degas the mobile phase as it is being used. The Aqueous IFD provides pure filtration of aqueous based HPLC mobile phases. Specifically, the Aqueous IFD is designed to work with mobile phases containing at least 20% of the aqueous component. The Aqueous IFD has a 0.2 µm hydrophilic nylon membrane for use with aqueous-based mobile phases. They have a polypropylene housing, the circumference of which is sealed by a security ring, fittings to accommodate 1?16-1?8 tubing, and an air vent on the inlet with luer lock cap to enable priming. The in-line filters work on the principle of "bubble point" the point of pressure at which gases will pass through a wet membrane. If pressure is maintained below the bubble point, the gas will not pass through the membrane and is trapped by the particular filter device.
