Aqueous IFD for HPLC mobile phase preparation

The Aqueous IFD is designed to work as an in-line filter with mobile phases containing at least 20% of the aqueous component. It has a 0.2 µm hydrophilic nylon membrane to support aqueous-based HPLC mobile phase preparation.

In-line filter construction and function

Whatman Aqueous IFD have a polypropylene housing 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.

An in-line filter works 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 filter device.
