Membrane Distillation (MD) is a relatively new and promising separation technology that is an alternative to more energy intensive methods such as reverse osmosis or distillation. MD is a thermally driven process where only vapor molecules transfer through a hydrophobic (water repellent), microporous membrane.
Thank you for trusting Sterlitech for your laboratory and research needs. As 2019 comes to a close, we hope we’ve served you well in transforming your ideas into reality, and we look forward to the upcoming year.
We like to remind our customers to be careful when feeding chemical solutions into their Membrane Filtration Systems. Ensuring that the chemical solutions are compatible with the wetted parts of these filtration systems or membranes will help you achieve consistent results and lengthen the service life of your systems to support future experiments.
Adult patients suspected of HIV infection can be quickly diagnosed with rapid test kits, enabling them to immediately start antiretroviral treatment. However, infants, the most vulnerable demographic, do not have this same privilege. Rapid test kits are unreliable for infant diagnosis until they reach 18-months of age. [1] In place of rapid test kits, the World Health Organization (WHO) recommends early infant diagnosis (EID) through polymerase chain reaction (PCR) methods to detect the virus through its genetic material.
The Aquaporin Inside® HFFO2 is a cross flow membrane module containing Aquaporin Inside™ hollow fiber membranes. With Aquaporin proteins coated on the interior surface (lumen side) of the fibers, the feed solution is circulated in the lumen and the draw solution is circulated in the shell. To learn more about Aquaporin Inside HFFO2 please see our most recent blog post.
Since 2016 we have supplied over 1000 Sterlitech Kato-Katz Kit to clinicians and researchers—enough materials to perform over 500,000 tests. These kits are used to efficiently diagnose intestinal schistosomiasis and soil-transmitted helminthiasis (STH) in the field. Recently, Dr. Johnny Vlaminck, a postdoc at the Parasitology Lab of Ghent University, used our kit during his fieldwork in Lao PDR and noticed a point of clarification in the product instructions.
A common question users of disk, syringe, and capsule filters ask is: How long will my filter last? Or, put another way: How much fluid can I expect to pass through my filter before it clogs? The answer to this question will help users select appropriately sized filters.
From their use in portable electronics and medical devices to electric vehicles, lithium (Li)-ion batteries have revolutionized our daily lives. Appropriately, the 2019 Nobel Prize for Chemistry has been awarded to M. Stanley Whittingham, John Goodenough, and Akira Yoshino for their major contributions in the development of the Li-ion battery.
The CK Nanofiltration Flat Sheet membranes (made from cellulose acetate) will be unavailable until further notice. If you are looking for a substitute membrane for your application, Sterlitech recommends the SBNF series of flat sheet nanofiltration membranes. SBNF series are chlorine-resistant(a) nanofiltration membranes suited for the treatment of surface waters and removal of organics and color. SBNF membranes are available in different dimensions, including sizes for CF016, CF042, and Sepa CF bench-scale test cells.
Sterlitech Syringe Filters play important roles in the purification processes inside laboratories and out in remote operations—applying to sample preparation for HPLC, pharmaceutical dissolution testing, and environmental monitoring, to name a few.
