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. 

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. 

Regulatory food standards require food products and supplements to have nutrition labels to enable consumers to make informed decisions and take control of their overall health. Commonly located on the back of your favorite snacks and food products, the nutritional label provides nutritional content, including calories per serving, and breaking it down to total protein, total cholesterol, total fat, sodium and total carbohydrates.

Cell culture workflows demand precision, flexibility, and sustainability. The cellQART® Half Pre-Loaded Well Plates meet these requirements by integrating gamma-sterilized, tissue-culture-treated PET membrane inserts into half of a standard 24-well plate-allowing researchers to load only the wells they need while preserving unused wells for future experiments.  

Sterlitech’s silver membranes are pushing the boundaries of biomedical research and analytical precision. These membranes can be used to harvest gingival crevicular fluid GCF during orthodontic procedures where accurate metabolic profiling is required. Their inert, porous construction is essential for preventing sample contamination and preserving molecular structure during proton nuclear magnetic resonance ¹H NMR analysis. This allows for the precise identification of a wide range of metabolites associated with bone remodeling inflammation and tissue adaptation.

As the world races toward a more sustainable future powered by renewables, we’re faced with a new challenge: what happens to the materials once they’ve served their purpose? 

That’s where the circular economy comes in. And behind the scenes, filtration plays a critical role in making it work.

Inorganic membranes distinguish themselves from polymeric membranes through their superior resistance to organic solvents, high thermal tolerance, and the absence of organic extractables and leachables. Unlike polymer-based materials, inorganic membranes are not composed of carbon-based molecular networks, which enhances their chemical stability. Among these, aluminum oxide (AO) membranes offer additional advantages, including precisely defined pore sizes, low adsorption, and minimal autofluorescence, making them particularly well-suited for high-resolution imaging and microscopy applications.¹ 

Sterlitech is proud to announce a new addition to our growing portfolio of specialty membranes. PrimeCare™ Blood Separation Membranes, now available for use in diagnostic and clinical applications where efficient plasma separation from whole blood is critical. 

One of the most reliable methods for synthesizing nanotubes and nanowires is template-assisted synthesis, which uses porous membranes as a structural guide to control the growth of nanostructures. Sterlitech’s track-etched polycarbonate (PCTE) membranes provide the ideal template for fabricating high-quality nanowires and nanotubes due to their precisely defined pore sizes and cylindrical structures.
