Binder-free glass fibre filters feature fast flow rates, high loading capacity, wide thermal tolerance and excellent precipitate retention.
Grade 691: Ideal for radioimmunoassy of weak beta emitters by scintillation counting and for filtration of precipitated proteins, cells and cell debris. Also used for gravimetric determination of airborne particulates and air pollution monitoring.
Grade 692: Recommended for use in filtration of suspended solids in industrial effluents and also as pre-filters for membranes.
Grade 693: Used for clarification and monitoring of suspended solids in wastewater and water and in marine chemistry to filter particulate components in sea water and in biochemistry for cell harvesting in radioimmunoassy procedures and for binders analysis.
Grade 696: Used for filtration and monitoring of air pollution and water, and also cell harvesting.
Grade 698: Due to its higher efficiency, in particle retention for smaller particles, than other glass fibre grades, 698 is suitable for the clarification of protein solutions, filtration of liquids prior to HPLC and critical applications.
