November 07, 2016Precision membrane filters in pore sizes larger than 5.0 microns are hard to come by, but not at Sterlitech. One of our more popular membrane materials is Polyethersulfone (PES). The membranes are ideal for use with difficult biological solutions that tend to clog most other polymer filters, and the 0.2 micron pore size PES filter is the industry standard for sterile filtering of liquids. Sterlitech PES binds very little protein and has a very asymmetric pore structure lending to improved performance.

November 02, 2016A large part of extracting commercially important compounds from various materials involves passing a type of solvent over the substance, then filtering out any unwanted debris and by-products. This filtration step can be difficult to optimize if too many undesirable compounds are also extracted; so how can you streamline the process?

We are thrilled to offer our congratulations to David J. Thouless at the University of Washington (just a few miles up the road from Sterlitech!), F. Duncan M. Haldane at Princeton University, and J. Michael Kosterlitz at Brown University. They collectively revealed the secrets of exotic states of matter!
This year’s Laureates opened the door on an unknown world where matter can assume strange states. The scientists have utilized advanced mathematical methods to study unusual phases, or states, of matter, such as superconductors, superfluids or thin magnetic films. Thanks to their pioneering work, the hunt is now on for new and exotic phases of matter. Entrepeneurs and scientists alike are hopeful of future applications in both materials science and electronics.
The three Laureates’ use of topological concepts in physics was decisive for their discoveries. Topology is a branch of mathematics that describes properties that only change step-wise. Using topology as a tool, they were able to

Parasites have met their match. Sterlitech, an industry leader in unique micro and sub-micron filtration products, announced today that its Kato-Katz Technique Diagnostic Kit is now available for immediate use in the field. The kit was developed in response to the unanimous difficulty among research groups, control programs, and health organizations to source a fecal-sample-based test kit. This kit enables field scientists to identify the presence of eggs from parasitic Soil-Transmitted Helminth (STH) worms in infected patients.
This is the first time that the kit has been made available from a source in the United States. Until now, research groups and health organizations alike had to rely on a limited availability of kits. Schistosome infections continue to be common where poverty prevails and hygiene behavior, water supply, and sanitation are often deficient. The worms live in the intestine of infected people and can cause a range of gastrointestinal and reproductive complications,

Numerous industries have a necessity to keep things clean and sanitary. Filters are an efficient and cost effective way to keep dirt, dust, bacteria, viruses and other small particulates out. The variety of applications are endless, and hundreds of product manufacturers employ filtration to keep things clean: from medication, to automobiles, to even your home.
Within the life sciences, it is often critical for researchers to keep the growth environments of key cells sterile for production of significant compounds. Contamination could mean the loss of hundreds of thousands of dollars’ worth of product. At university labs, cell biologists and clinical researchers alike utilize small vent filters and devices to keep their cell growth devices and growth media free of any bacteria or molds that could damage their cell lines in their ongoing research. Sterlitech offers standard syringe-filter type vents, custom syringe filter vents, and custom adhesive-backed vent discs in a variety of sizes

Sterlitech is pleased to offer a “plug and play” DCMD test cell. The first commercially available bench-scale cross/tangential flow test cell, that mimics conditions representative of large-scale DCMD systems with minimal amounts of membrane or product. This offers researchers fast and accurate performance data to easily evaluate the performance of membranes and/or the membrane separation processes.
“Adding the DCMD test cell to the Membrane and Process Development product line complements this line of product by offering researchers a bench-scale cross/tangential flow test cell for evaluating Temperature-Driven membrane separation processes,”
- said Sepideh Jankhah, Product Manager at Sterlitech Corporation.How it works: the liquid to be treated is circulated in direct contact with the feed side of the membrane in the Sterlitech’s DCMD cell. A cold liquid solution is circulated in direct contact with the permeate side of the membrane. Both the feed and the cooling solution are circulated
