Aura=s 47 mm Teflon filter membranes are made of pure of PTFE and therefore have no extractables. The substantial thickness of the membranes (250 micron) allows the fabrication of the membranes without requiring backing material, make them easy to handle and allow them to be reused numerous times. They are chemically inert and can be used interchangeably for organic and aqueous solvents. Due to the membrane=s strength, if necessary, liquids can be filtered using pressures exceeding the membrane=s water initiation pressure or with the aid of wetting agents such as methanol. The functional pore size is 1.5 +/- 0.5 microns.

Among many other application of these membranes is  the filtration and degassing of HPLC solvents in conjunction with Aura=s filter degasser (Cat # IFDA).

The membranes are packaged 10 per package.
