Product overview
Ashtech Science membrane filter discs are used for sample preparation, solvent clarification and general vacuum or pressure filtration in analytical laboratories. They are listed as compatible with HPLC, ICP-MS and routine laboratory applications.
The range covers mixed cellulose esters (MCE and CA-CN), nylon, PTFE, hydrophilic PVDF, PES and polypropylene, so the membrane can be matched to aqueous, organic or aggressive samples. Discs have a uniform pore structure, high chemical resistance and low extractables.
Discs are supplied in 13, 25 and 47 mm diameters with 0.22 or 0.45 µm pore sizes, in packs of 100. Ashtech also supplies matching filter holders, funnels for 47 mm and 50 mm discs, adapter kits, tubing and clamps.
