Supplier: Merck

Mitex™ PTFE hydrophobic membranes are unaffected by almost all liquids, including organic solvents, concentrated acids and bases, propellants, and cryogenic fluids. They are unbacked, but easy to handle, combining the convenience of a backed membrane with the versatility of a pure PTFE membrane.

Supplier: Merck

A 50 mm diameter non-sterile syringe filter with a 2 µm pore size glass fiber membrane.

Supplier: Merck

These PTFE white hydrophilic membrane compatible with all commonly used HPLC solvents. The membrane undergoes a special treatment process to remove any residual extractables, to provide clearer analysis results. They are widely used for HPLC mobile phase filtration, clarifying acids, bases and dilute protein solutions and isolation of RNA.

Supplier: Sartorius

Elimination of particles from samples prior to HPLC or other chromatographic analysis is essential in order to maintain the integrity of the chromatography column and to maximise its operating life time. Minisart® syringe filters optimised for sample preparation consist of a polypropylene (PP) housing and membrane components featuring maximum chemical compatibility and minimum extractables to ensure excellent results. Due to the typical range of volumes from less than 1 ml to 100 ml these filters are available in three different diameters with an effective filtration area of 0,12, 1,7 and 4,8 cm².

Supplier: Sartorius

Binder free glass microfibre filters are made of 100% borosilicate, are highly pure and extremely white. They are recommended for analytical and gravimetric analyses and also as prefilters. These filters combine fast flow rates with high load capacity and the retention of very fine particles.

Supplier: Cytiva (Formerly Pall Lab)
