Whatman™ aqueous in-line filter/degasser (IFD)
Designed to provide filtration of aqueous based HPLC mobile phases.
Whatman™ aqueous in-line filter/degasser (IFD)
Designed to provide filtration of aqueous based HPLC mobile phases.
Overview
The Whatman™ aqueous IFD device is a polypropylene housed in-line filter/degasser (IFD) with nylon membrane that connects to an HPLC line to simultaneously filter and degasses during mobile phase preparation.
- 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
The devices 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.
