This month, Sterlitech Corporation was named as one of the fastest growing private companies in America by Inc. Magazine. This is the third year in a row that Sterlitech has made the Inc. 5000 list. Sterlitech ranked as the 75th fastest growing company in the Seattle area with a revenue growth of 117% over the course of 3 years. We would like to thank all of our customers, old and new, for supporting us and making our incredible growth possible. We’re proud to provide the highest quality products to R&D groups, universities, pharmaceutical labs, and environmental scientists. Of course, we’d also love to hear what you think we can do to make the list again next year, so please leave a comment below.

As a leading manufacturer and marketer of membrane filters, Sterlitech fields a lot of burning questions about membrane filtration for our customers.  In this article, we tackle some of the most frequently asked questions we receive about the basics of membrane filtration.  If you have a question that isn’t covered below, be sure to let us know here. Q: What is the difference between hydrophilic vs hydrophobic membranes?A: Hydrophilic filters posses an affinity for water and can be wetted with almost any liquid. Sterlitech carries a wide variety of hydrophilic membranes, including:

• Silver Metal
• Polyethersulfone (PES)
• Glass Fiber
• Polycarbonate Track Etch (PCTE)
• Polyester (PETE)
• Mixed Cellulose Esters (MCE)
• Nylon
• Cellulose Acetate

Hydrophobic filters are just the opposite; they lack an affinity for water and are best suited for venting applications. Examples of hydrophobic filters include Sterlitech polypropylene membranes and Sterlitech PTFE filters, which are either laminated

People do strange things for attention. Children throw tantrums, celebrities shave their heads and UNICEF builds a machine to take the sweat from your clothes and turn it into drinking water. UNICEF, at least, is trying to raise awareness of the lack of clean water for children with its unusual machine. Unveiled during the Gothia Cup, and built by Swedish engineer Andreas Hammar, the aptly named Sweat Machine works by using membrane distillation to separate water from other components of sweat. Unlike other membrane-based processes of water purification, such as reverse osmosis, membrane distillation is a thermally-driven process that employs a hydrophobic, microporous membrane. The water (or sweat) to be processed is heated, while the water on the permeate side of the membrane is kept cool. The temperature difference across the membrane creates a corresponding difference in pressure which pulls water, in the form of vapor, over to the permeate side of the membrane. Water’s naturally high

Today, we have a new video that shows you how to assemble a Sepa CF II cell and get it ready to perform reverse osmosis, nanofiltration, ultrafiltration or microfiltration at pressures up 1000 psig (69 bar). To learn more about the Sepa CF II, you can visit our Sepa CF II page here.  

A few weeks ago, James Cameron, director of Hollywood blockbusters "Titanic" and "Avatar," testified before the U.S. Senate's Oceans, Atmosphere, Fisheries, and Coast Guard Subcommittee, urging them to maintain federal programs aimed at oceanic research.  Although he is best known for making movies, James Cameron is also a deep sea explorer, reaching the bottom of the Mariana Trench in the Pacific Ocean last year, more than five miles below the ocean surface.  The data taken during that dive revealed new species of sea cucumber, worms, and amoeba, all of which are remarkable for their ability to survive in a such an extreme environment. These discoveries highlight the gaps in our knowledge of the oceans, despite the fact that they cover more than two-thirds of the planet's surface.  A large portion of the world's population live near the coasts and that portion is expected to grow as people migrate to coastal cities over the course of the next century.  Knowing the effects of climate
