Sterlitech now offers an Acrylic Sepa Test Cell in an additional channel depth: 34 mil. The original Acrylic Sepa Test Cell utilizes a 75 mil channel depth and has been widely used by researchers over the years. In many experiments involving the Sepa cells, combinations of stainless steel shims and polymeric spacers (with differing thicknesses) are installed in the cell to reduce the channel depth or mimic the hydrodynamic conditions of commercially available spiral-wound elements.

The use of polymeric membranes for filtration of non-aqueous solutions started around 1960 and has been developed significantly since then [1]. Today, non-aqueous membrane filtration applications in chemical and pharmaceutical processing account for more than 25% of the global total polymeric membrane market [2].

As we grow in understanding the significance different organisms have in the ecology of an environment, it helps tremendously if we know which organisms inhabit that environment – whether they’re supposed to be there or not. One method that is gaining widespread use, and relies on a simple filtration method, is the analysis of environmental DNA (eDNA) from local waterways.

Last month, we described the considerations associated with predicting filter service life and how total throughput can be estimated through experimentation. In this second installment, we will examine four filter selection strategies for maximizing service life in continuous-use applications. These aspects consider chemical compatibility, temperature, binding characteristics, and pore size.

DuraMem® and PuraMem® membranes are now available as a valuable addition to our Chemically Resistant Membranes product line. Duramem® and Puramem® polymeric membranes, made by Evonik, are market leaders for Organic Solvent Nanofiltration (OSN).

How about a nice tall glass of ice-cold beer… made from recycled sewage water? Did you hesitate? Well, now let’s think about it: most breweries use some combination of hops, malted barley, yeast, and…. well… clean water! But beer from recycled wastewater? That’s exactly what took place March 19-10 at the 2017 WateReuse California Annual Conference in San Diego.

You spoke and we listened! Many of you expressed difficulty in finding additional application or technical specifications while viewing a product page on www.sterlitech.com. Thanks to your feedback, each tab is now individually outlined and highlights when moving your mouse cursor over a given tab; information is just one click away! Simply place your mouse curser over the “Application/Specification” tab near the middle of the page (example shown to the left) and click. This will open the tab, and you will then have all pertinent information on your screen.

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?
