March 11, 2020Why Perform a Bubble Point Test? In the bubble point test, pore size rating is determined by measuring the lowest air pressure needed to overcome the surface tension between the wetting liquid and the membrane pores in a fully wetted membrane. This pressure level, known as the bubble point, is signaled by the first appearance of a steady stream of bubbles observed from a special disc filter holder through the downstream side of the membrane filter. The measured bubble point is then correlated to the membrane pore size diameter.

February 14, 2020What is Pittcon? Now in its 70th year, Pittcon is a premier, annual global expo on laboratory science. It was first organized by the Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy in 1950. Since then, it has expanded to appeal to anyone involved in the lab equipment sector. This year, Pittcon will be held at McCormick Place, Chicago IL, from March 1 – March 5, 2020.

February 14, 2020Have you ever wondered when to use vacuum filtration versus positive pressure filtration for your project? We recommend vacuum filtration when the application requires collection and analysis of particles or microorganisms retained by the filter. Compared to pressure filtration systems, vacuum filtration assemblies tend to be more economical and convenient as they allow for easier access to the liquid being processed.

January 13, 2020Ultrafine particles (UFPs) belong to a class of primary air pollutants called particulate matter (PM). Other types of PM include coarse particulate matter (PM10) and fine particulate matter (PM2.5). With a diameter of 0.1 micron or less, UFPs are the smallest known particles of PM. To put its relative size into perspective, UFPs measure 700 times smaller than the average diameter of a human hair.

January 10, 2020Membrane Distillation (MD) is a relatively new and promising separation technology that is an alternative to more energy intensive methods such as reverse osmosis or distillation. MD is a thermally driven process where only vapor molecules transfer through a hydrophobic (water repellent), microporous membrane.
