Sterlitech recently attended Pittcon Conference + Expo 2026, held in San Antonio, Texas, where our team connected with scientists, researchers, and industry professionals from across the analytical and laboratory community.

Pressure-driven membrane technology has become a cornerstone process for protein separation and purification, offering a scalable and gentle alternative to traditional thermal and chemical methods Among the various membrane-based processes available today, pressure-driven processes, microfiltration (MF) and ultrafiltration (UF), are most applicable due to their simplicity, scalability, and gentle operating conditions. These processes are used across biotechnology, dairy, food processing, and pharmaceutical industries. 

Microplastics are everywhere. Scientists have found them in the deepest ocean trenches, in Arctic ice, in agricultural soils, in drinking water, and increasingly, inside the human body itself. Researchers have identified microplastic particles in human blood, liver tissue, and even brain samples. Yet despite their ubiquity, one fundamental question has remained stubbornly difficult to answer: what exactly happens to these particles once they enter a living organism?

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.
