Polypropylene (PP) membranes have long been used across laboratory, pharmaceutical, medical device, and microelectronics industries. Their inherent hydrophobicity, broad chemical compatibility, and reliable airflow performance made them a preferred material for solvent filtration, particle control, and venting applications. As availability of polypropylene membrane products decreases, engineers and process specialists are evaluating alternative materials to maintain performance and supply continuity. 

Starting January 1, 2026, the following items from Rocker Scientific will feature new updates:  

Toray flat sheet products have been discontinued by Sterlitech and inventory has been depleted of the UTC-73HA, UTC-73AC, UTC-73UAC, and UTC-82V.  For more information or if you need assistance finding a suitable replacement product, please contact us!

Membrane selection critically impacts device performance, reliability, and regulatory compliance in specific applications. For diagnostic equipment, point-of-care devices, and therapeutic systems alike, three technical considerations determine the optimal solution for accelerating time to market while meeting demanding performance specifications.

What if the water flowing beneath our cities could tell us how healthy our communities really are?

Membrane-based desalination technologies play an important role in addressing global freshwater scarcity. Processes such as reverse osmosis (RO), nanofiltration (NF), forward osmosis (FO), and membrane distillation (MD) can be utilized due to energy efficiency, modularity, and high separation efficiency. However, the performance of these systems is governed by complex and interdependent variables, including membrane structure, surface chemistry, operating conditions, and feed-water composition. 

Pittcon brings together scientists, researchers, and industry leaders to explore the newest advancements in laboratory science and technology. In 2026, the conference heads to San Antonio, Texas, at the Henry B. Gonzalez Convention Center.

As we turn the page into a new year and our 25th anniversary in the industry, I want to take a moment to thank you for your continued trust and partnership. We truly value the opportunity to support your work and remain committed to helping you achieve your goals.

Acetonitrile is one of the most widely used organic solvents in the pharmaceutical industry. Its polarity, miscibility with water, and low viscosity make it suitable in applications such as high-performance liquid chromatography (HPLC), active pharmaceutical ingredient (API) synthesis, and ingredient concentration applications.

We’re excited to introduce Lexi Simpkins, Ph.D. as Sterlitech’s new Bioprocessing Sales Representative!
