Whatman Aqueous In-Line Filter/Degasser (IFD)

Description

Faster than traditional methods of HPLC mobile phase preparation, saving time in the laboratory
Provides pure filtration of aqueous mobile phases without expensive degassing equipment
Chemically resistant polypropylene construction enables reliable filtration
Can be integrity-tested with the bubble point method
Includes compression end fittings – for replacements, see our IFD end fitting kit

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.
