Sterlitech Corporation has been providing the best in laboratory filtration products and equipment for over 14 years.  For 13 of those years, Shiela Naegele has been there, helping Sterlitech grow into the industry-leading company that it is today.  She started here manufacturing our silver membrane filters but has since worn nearly every hat she could think to put on, including shipping, marketing, quality control, and receivables.  These days, her primary focus is in procurement.  In short, if you have ever ordered anything from Sterlitech in the last decade, Shiela probably had a hand in making sure that you receive a quality product on time, and for the best price we can offer.

Sterlitech Corporation is proud to offer a new range of compact, quiet, and affordable vacuum sources with the new TLD3000 and TLD5000 diaphragm vacuum pumps. Perfectly suited for vacuum filtration in laboratory analytical procedures, the new pumps require little to no maintenance, built with polytetrafluoroethylene (PTFE) contact surfaces for broad chemical compatibility. With a 1/7 horsepower motor, The TLD3000 vacuum pump can deliver 22 in-Hg of vacuum and 20 L/min of free air displacement. The bleach-resistant TLD5000 vacuum model has a 1/5 horsepower motor for a maximum vacuum of 24 in-Hg and

 With its latest polyacrylonitrile (PAN) membrane, Sterlitech Corporation offers a hydrophilic filter that does not sacrifice selectivity to achieve faster flow rates in comparison to nylon or polyethersulfone (PES).  Its unique nanofiber mesh construction combines extremely fine pores with significant open space to allow easy liquid flow while trapping particulates as small as 0.2 micron in width. “This technology is already in use for water filtration in applications where low energy is required,” said Sterlitech President Mark Spatz.  “We are excited to introduce this technology at Sterlitech because we know it has a place in laboratories or small-batch processes where its uniquely high flux is an asset.” This novel membrane’s performance is attributed to its unique construction.

It is created by extruding extremely fine PAN nanofibers onto

Complementing our existing CF042 and Sepa CF membrane/process development cells is the new CF016.  Designed for applications with smaller membrane samples or low solution volumes, the CF016 comes in two varieties: a crossflow version that can perform reverse osmosis, nanofiltration, ultrafiltration, and microfiltration separations and a forward osmosis version that can be further modified to perform pressure-retarded osmosis.

In the crossflow version of the the CF016, feed solution enters the membrane cavity in the cell body, flowing tangentially across the membrane surface. Applied pressure forces a portion of the stream to permeate the membrane and flow through the permeate carrier located on the underside of the top half of

We had a great time with you at the ASM and NAMS Conferences earlier this month.  You'll have another chance to see us at Booth #83 the NAOSMM tradeshow in Long Beach. We'll be there from July 26-31 so don’t miss out on the opportunity to discuss your filtration needs and get your questions answered from the experts!

The BW30FR line of reverse osmosis membranes from Dow is being discontinued. At this time, these membranes do not have any direct replacements, although we still carry other Dow membranes which may be suitable for your application.  To aid comparison and help you select a possible replacement, the table below includes the technical specifications of the Dow membranes we offer:

Toray is discontinuing the production of the 70HA and 72U reverse osmosis (RO) membranes. These membranes are being replaced in Sterlitech's line-up by the new 73HA and 73U RO membranes, respectively. The table below lists the specifications of all of our current offerings from Toray for easy comparison.  To browse our complete selection of RO membranes or to place an order with us, click here.
