In biomedical research, extracellular vesicles (EVs)—especially exosomes—have become a key focus due to their role in intercellular communication. These nano-sized lipid-bilayer vesicles (30–150 nm), secreted by nearly all cell types, transport proteins, lipids, and nucleic acids, positioning them as valuable tools for diagnostics and therapeutics. However, their small size and low abundance in biological fluids make conventional methods for isolation and purification challenging.  Ultracentrifugation is labor-intensive, costly, and can damage exosome structure under high centrifugal forces, while precipitation and size-exclusion chromatography often produce low-purity samples contaminated with proteins and other non-exosomal particles. 

As mRNA-based vaccines and therapies continue to proliferate, the downstream purification process, particularly Tangential Flow Filtration (TFF), has become a critical efficiency and cost focus. Yet, data on optimizing TFF for mRNA is notably scarce, complicating process development. 

As air pollution continues to pose significant threats to public health and the environment, the demand for accurate and efficient air quality monitoring has never been more urgent. Among various pollutants, PM2.5, which are fine particulate matter with a diameter of 2.5 micrometers or less, stands out due to its ability to penetrate deep into the respiratory system and bloodstream, contributing to a wide range of health issues. 

August 26 is National Dog Day, a perfect moment to celebrate the dogs we love—and protect their health with proactive care. One critical but often overlooked step in safeguarding your dog from disease is routine testing for heartworm. 

We're thrilled to welcome Anna Solomonova to the Sterlitech team as our new Sales Manager for Membrane Process Development! 

We’ve made an exciting update to our website to help you get to the products you need faster and more intuitively. 

Sterlitech is excited to participate in ADLM 2025 in Chicago, IL, in partnership with Rocker Scientific. This event, hosted by the Association for Diagnostics & Laboratory Medicine, brings together industry leaders advancing innovation in clinical and laboratory science. 

When we think of filters, we often picture a lab setting: membrane discs separating particles, removing impurities, and clarifying liquids for analysis or production. But have you ever considered how your daily sunscreen acts as a personal filter? Much like the membrane filters used in laboratories and industrial processes, sunscreen functions as a protective barrier. This time, it stands between your skin and the sun. 

Industrial wastewater treatment presents unique challenges due to complex feed compositions and high salt concentrations. Traditionally, safe disposal or reuse of such wastewater has aimed to minimize environmental risks while conserving freshwater resources. For instance, in offshore oil and gas operations, produced water is often treated with moderate technologies—such as dissolved air flotation or chemical precipitation—before ocean discharge.

We are excited pleased to introduce the new Food and Beverage section on Sterlitech.com. This section organizes key filtration products specifically for the food and beverage industry into a dedicated space, making it easier for customers to find the solutions they need. With improved visibility and a streamlined navigation experience, it's now simpler than ever to explore filtration solutions for food testing, quality control, and shelf-life studies.
