This Whatman brand Solvent IFD in-line filter/degasser connects directly into an HPLC line to simultaneously filter and degas the mobile phase as it is being used. The Solvent IFD provides pure filtration of organically based HPLC mobile phases. It has a 0.2µm high-flow polypropylene membrane for mobile phases containing organic solvents. It has polypropylene housing, the circumference of which is sealed by a security ring, fittings to accommodate 1/16inch-1/8 inch tubing and an air vent on the inlet with luer lock cap to enable priming. This in-line filter works on the principle of inchbubble pointinch - 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. Applications include: HPLC analysis, pharmaceutical research and analytical chemistry. (O-Rings included.) 10/Pack. Whatman # 6725-5002.
