Membranes
I.W. Tremont offers a line of high quality
membrane filters available in a variety of materials,
diameters and pore sizes and suitable for a wide range
of applications including cell retention, In Vitro Diagnostics,
particle collection, clarification and sterile filtration of
aqueous solutions, particulate analysis and microbiological analysis.
I.W. Tremont polymeric nylon and PTFE membranes are cast by leading OEM raw material suppliers who also supply many of the most widely known competitive brands. All materials are held to the highest quality standards with our in house testing and quality assurance using the latest materials science instrumentation. Converting and packaging is performed in Hawthorne, New Jersey to offer the broadest product range with high stock level availability and rapid shipping. Our production method brings exceptional value and quality.
These materials are also offered in custom product variants and OEM. Inclusion of these and other materials within structured devices such as syringe filters and inline housings can be performed quickly with surprisingly low minimums.
The following membrane materials available include:

We offer OEM capabilities for engineering, molding and insertion of many additional membrane and membrane/pre-filter options. We can work with most of our own membrane and specialty materials as well as convert your supplied product. Please contact us for full engineering capabilities as well as process flow and project management services in this field.
Tremont offers an impressive list of manufacturing capabilities and expertise in glass microfiber and cellulose filter media. We leverage a longstanding and contractual relationship between several mills to put 6 papermaking machines and formers into production. With this enormous capacity at our disposal, we are able to take a project from lab bench through pilot scale and ultimately full production with ease.
Our partner mill output exceeds 120 grade variants manufactured in the USA and internationally. With chemists and scientists of several disciplines, experienced papermakers, the finest controls-on-machine plus a rigorous QA protocol, it is not often a project challenge is beyond our capability.
Paper making capabilities:
After the papermaking process is complete, our experienced converting staff brings your project from large master rolls down to narrow reels or sheets with ease. Sheeting, die cutting and other unique converting operations are performed at our Hawthorne, NJ facility under our strict ISO production environments.
