For consumers using disk, syringe, and capsule filters it is a common FAQ: How long will my filter last? Or, to put it another way: How much fluid can I expect to pass through my filter before it clogs? This seems to be a simple and reasonable question for a filter consumer: Would any of us purchase a product without an understanding of its service life? However, this apparently simple question is deceivingly complex as a multitude of factors influence filter service life. Service life can be defined as the total volume of fluid that is passed through a normal flow filter until it becomes clogged; this is commonly referred to as total throughput. It is nearly impossible to predict total throughput, even with a good understanding of the application. So, as a filter manufacturer, how would we suggest approaching this challenge?

In order to provide a safe work environment, better control of vapor wastes needs to be implemented. EZ waste technology has become readily available to improve the containment of volatile liquids and prevent vapors from escaping into laboratory air. Learn about how to prevent the dangers of hazardous waste and the technology behind the closed waste system with an activated carbon filter, such as the EZ waste system. Download EZwaste whitepaper for more detail and additional instruction.

Do you know today, there are over 663 million people, who do not have safe water supply and suffering with health problems from use of dirty water?

Sterlitech is proud to announce the availability of Aluminum Oxide (Al₂O₃) inorganic microporous membrane filters. These filters are finding use in several specialty applications, ranging from nanomaterials synthesis (where they perform best), graphene synthesis (Buckypaper) and testing, HPLC mobile phase filtering, liposome filtering, environmental monitoring, and more! The Sterlitech alumina membranes are also a suitable alternative to Whatman Anodisc© filters.

These anodized alumina filters are distinguished by swift filtration speed owing to their high pore density, efficient separation, and high purity. The inorganic material is constructed of numerous, narrowly distributed pores in the form of honeycombs yielding a high degree of open space.

Adding to their features, these membranes become almost completely transparent when wet, and display minimal auto-fluorescence, making them well-suited for epifluorescent light microscopy. As particles are retained on the smooth surface, the

Sterlitech Corporation’s unique track-etch polycarbonate membrane filters are helping MIT Researchers pioneer a faster and less expensive means of identifying key genes turned on in response to infection or diseases, as featured in the February 13 issue of Nature Methods from the Shalek and Love Labs at Massachusetts Institute of Technology.

Sterlitech has developed a new support for the Sepa Cell Assembly to improve ease of handling and facilitate safe operation when assembling the cell or changing membrane coupons and O-rings.

Continuing demand for low energy solutions to separation challenges have fueled Sterlitech’s latest product release: an Air Gap Membrane Distillation Cell. The first commercially available bench-scale tangential flow test cell of its kind, it mimics conditions representative of large-scale systems with minimal use of membrane or product. The AGMD cell offers researchers fast and accurate performance data to easily evaluate the performance of membranes and/or the efficiency of a given process with respect to their application.

TriSep SBUF flat sheet membranes are being discontinued by the manufacturer. Limited quantities of these flat sheet membranes is available at the moment, for more information or if you need assistance finding a suitable replacement product, please contact Sterlitech at [email protected]

Sterlitech is launching Synder Filtration’s new "SM" flat sheet membrane. This is a PES based ultrafiltration membrane commonly used for specialty protein separation, skim milk protein concentrate/isolate production and beverage clarification. SM membrane conforms to 3-A, FDA, and USDA sanitary standards and provides good resistance to pH and temperature as well as a high resistance to fouling.

Membrane fouling, defined as the accumulation of particles and organic matter at the surface or in the pores of membranes occurs during membrane filtration. Membrane fouling results in membrane performance loss, i.e. lower rejection values, lower permeate flux and higher pressure drop, which translates into higher operational cost. The extent of fouling depends on the feed quality, operating conditions, membrane characteristics and module design.
