The name Lockheed Martin invokes images of high tech aircraft, secret weapons, and other technologies that seem a whole lot more exciting than a reverse osmosis (RO) membrane.  However, Perforene™, Lockheed Martin’s latest innovation, promises to be an exciting new development for RO desalination. It’s made from graphene, an allotrope of carbon where the atoms arranged in hexagonal cells to make a sheet that is only one atom thick.  The next thinnest RO membrane is about 500 times thicker than Perforene™.  It is the almost impossible thinness of the membrane that makes it so exciting for RO; it takes about 100 times less energy to push water through the membrane when compared to the average RO membrane available commercially today. The Perforene™ membrane was developed

Starting today, Sterlitech’s selection of Hollow Fiber Filter Cartridges will no longer be available on our website. These filter cartridges from Watersep were ideal for cell culture clarification, cell harvesting, and for concentrating antibodies and enzymes. Unfortunately, we currently do not carry an equivalent product that can serve as a direct replacement for these hollow fiber filter cartridges. However, if you need them, you can contact us, and we can put in a special order for you. Think of them as part of our “Secret Menu.” Next month, you will be able to order a complete bench scale system “animal style.” To learn more about hollow fiber membrane filter cartridges, you can visit Watersep’s website here.  

Toray has discontinued the production of their 80B Reverse Osmosis Membrane. But fear not, because they have also started producing a successor, called the 80E, that Sterlitech will be offering on our site. Both the 80B and its new, functional equivalent, the 80E, are polyamide membranes that are typically used for seawater desalination. A complete list of the product numbers we are discontinuing and the product numbers of the new membranes can be found below: Discontinued 80B Membranes;

• YM80BSP475
• YM80BSP195
• YM80BSP42
• YM80BSP18

New 80E Membranes;

• YM80ESP475
• YM80ESP195
• YM80ESP42
