Sterlitech Grade A Glass Fibre Filters – Fine Porosity Filters for Protein Filtration and Airborne Particulate Monitoring
Sterlitech Grade A glass fibre filters are binderless borosilicate microglass filters with fine porosity, fast flow rates, and a nominal retention of 1.6 µm. Widely used in protein and cell filtration, these filters are also ideal for radioimmunoassay (RIA) of weak beta emitters by scintillation counting, and for the gravimetric analysis of airborne particulates.
The absence of binders ensures high purity and low extractables, making Grade A a reliable choice for analytical workflows requiring both precision and minimal background interference.
