As a membrane filter manufacturer, Hawach provides a series of pore sizes (0.1μm, 0.22μm, 0.45μm, 1.0μm, 3.0μm, 5.0μm, 10μm), high porosity, large dirt holding capacity, recoil and high-temperature disinfection; good pressure resistance. Thin, and highly porous, our PTFE disc membrane has OEM service and their sizes could be customized.

PTFE membranes do not impart any extractables to the filtrate. PTFE is an ideal membrane for transducer protectors, since it blocks water vapor and is also ideal for filtering and de-gassing chromatography solvents. PTFE can be treated to be hydrophilic for applications where it is deemed necessary. View PTFE Membrane Filters View Hydrophilic

Minisart ® SRP with chemically inert hydrophobic PTFE is suitable for venting as well as harsh solvents with a pH of 1 - 14. Type 17573 with a pore size of 0.2 µm can be used for sample preparation and sterile filtration. It has a male luer slip outlet. Version K is a non-sterile pack of 50. Units can be sterilized by autoclaving or EO.

Due to its hydrophobic nature the PTFE membrane functions as a water barrier and does not become wetted by aerosols. This keeps the hydrophobic venting filter permeable for gas or air! The housing of the filter is made of MBS (Methacrylate butadiene styrene) which has a limited compatibility with alcohols but is free of phthalates and passes

biological fluids and gases is usually done with 0.2 or 0.22 µm pore filter membranes. Clarification and prefiltration of solutions and solvents is best accomplished with 0.45 µm or larger filter membranes. Prefiltration to improve filter performance can also be accomplished by the use of glass fiber prefilters that can be purchased separately.

With biologically inert mixtures of cellulose acetate & cellulose nitrate, MF-Millipore membranes are widely used in analytical & research applications.

Syringe Filter Solvent Compatibility [Charts] - Growing Labs. There are so many solvents and syringe filter/membrane materials that it can be tough to remember which combinations are safe and which are corrosive. These tables show the compatibilities between 5 materials (CA, nylon, PES, PTFE, and PVDF) and 75 common solvents (including acids, alcohols, and nitrogen solvents).

GVS Laminated PTFE filters are made of a polytetrafluoroethylene polymer (PTFE) laminated to a polypropylene support for improved durability and easy handling. These filters are chemically compatible with strong acids and most aggressive solvents such as alcohols.
