As part of our goal to enable researchers, Sterlitech carries a comprehensive assortment of membranes for use in bench-scale filtration systems (such as our HP4750, CF016, CF042, and Sepa CF cells). We offer membrane filter sheets designed for use in reverse osmosis, nanofiltration, ultrafiltration, microfiltration, and forward osmosis applications.  Additionally, we offer membranes for membrane distillation and where this is a need for chemically resistant membranes.

We are continually adding new products to our offerings; please visit the Flat

Legalization and the increasing demand for cannabis products have transformed technology used for extracts from simple to sophisticated in recent years. 

Extract processing typically begins with a solvent wash, followed by winterization and/or filtration to concentrate the active compounds and to remove large impurities such as waxes. A final purification step aims to remove chlorophyll, thus producing the desirable amber concentrate, ready to be further modified into valuable end products. This time and labor consuming process can further be simplified and improved. Removing color while preserving THC and CBD’s still remains a challenge.

Our solution for addressing both needs:

According to Evonik Corporation’s recent presentation, Organic Solvent Nanofiltration (OSN) Duramem^TM Membranes may not only simplify the

Water molecules are ubiquitous, vital, and may have the world’s most well-known chemical formula (H₂O). The properties of water are quite unique; its solid state is less dense than its liquid state, raising pressure lowers its melting point, and it exists as a liquid at room temperature despite low molecular mass. Even more unique is the water molecule’s ability to exist as two distinct nuclear configurations called spin isomers.

The two spin isomers of water molecules differ based on the direction of the nuclear spin of the two hydrogen nuclei. If the two hydrogen nuclei have parallel spins, the molecule is known as ortho-water. If the two hydrogen nuclei have opposite spins, the molecule is known as para-water. Water at room temperature always contains a mix of these two spin isomers and, until recently, it has been nearly impossible to study them separately.

Now a study co-authored by Stefan Willitsch at the University of Basel has successfully isolated the

The National Association of Scientific Materials Managers (NAOSMM) will be holding its 45^th Annual Conference and Trade Show, July 22-27^th in Spokane, Washington - just over the mountains from Sterlitech. We are excited to participate in this trade show for the 5^th consecutive year and hope to meet with attendees at our booth, #22! We’re also looking forward to co-sponsoring the Tuesday Evening Out event at the show, as part of the Independent Laboratory Distributors Association (ILDA).

This conference provides an opportunity for its over 500 members in the scientific industry to discuss current trends and issues, participate in seminars and workshops, and preview new products from vendors. NAOSMM’s
