Join Sterlitech's membrane and process development scientists for a live webinar presentation on our membrane test skids.


We will be discussing how our customizable test skids can enable you to explore new filtration applications in the lab. This webinar will provide an overview of the features and applications of the product line, with a special focus on our multi-functional Convertible Test Skid. We will also have plenty of time for Q&A after the presentation and look forward to answering any questions.

We have observed a growing need in the research community for a high pressure stirred cell to test 25 mm membrane discs. The Membrane Area Reducer was developed in collaboration with Christopher M. Stafford, PhD. and Chris Amigo, Machinist, at the National Institute

When selecting the right membrane for a microfiltration application, one of the most important factors to consider is membrane wettability. While hydrophobic membrane filters are ideal for air and gas filtration, they are not suitable for filtering aqueous solutions. Hydrophilic membrane filters, on the other hand, are commonly used for clarification and sterilization of water-based fluids but are not typically used for venting applications.

To conceptualize the forces contributing to membrane wettability, you can start by thinking of a water drop on a material’s surface.

The Sterlitech Cannabis Extraction Guide was introduced last year to provide a resource for our customers and illustrate how our products can be utilized in cannabis extraction methods. To stay up to date with an ever-evolving industry, we are now releasing a new edition of the guide.

Included in the 2018 edition of the guide are updates to our outline of ethanol extraction methods, and an introduction to Organic Solvent Nanofiltration (OSN) as an alternative to conventional ethanol extraction. As you can tell from the description: these membranes are compatible with organic solvents including ethanol. OSN removes oils, waxes, pigments, and other impurities in one step – eliminating the need to winterize and sequentially filter extracts. Solvent removal and recovery can also be accomplished with OSN, compared to using an expensive rotary evaporator system.

Sterlitech has recently discontinued sale of the MS7-Pro Analog Magnetic Stirrer from Scilogex. For fans of the MS7 model, we recommend the MS7-H550-Pro Hotplate Stirrer. 

If you're looking for a comparable stirrer (and don't need the heating function), we still have a selection to choose from in the Magnetic Stirrers & Hotplates section of our website. We are happy to assist with finding the right stir plate for your lab - please contact us with any questions!
