Higher Pressures for PTFE Regulators

January 7, 2015 by Jeff Jennings

2015: Equilibar recently expanded its 100% PTFE Teflon regulator options to allow higher pressure ratings in liquid fluid service only (not gas service). Using 1/8″ and 1/16″ PTFE tubing, these regulators can now be rated to 250 psig and 500 psig, respectively. These units use PTFE/Glass diaphragms and FFKM wetted O-rings. The LF1 back pressure Read More

BIOPROCESSING FOCUS: Preventing pump push-through with a BPR

Maintaining the purity and integrity of biological substances is one of the most important aspects of bioprocessing applications. While sanitary pumps are designed to minimize contamination risks, pump push-through flow remains a significant challenge. Preventing pump push-through is key to maintaining quality. Pump push-through flow occurs when head pressure at the pump inlet pushes fluids Read More
