Product Description
Glass Microfibre Filter Grade GF/A
This grade filter paper offers fine particle retention and high flow rate, as well as good loading capacity.
• Used for high-efficiency general purpose laboratory filtration, including water pollution monitoring of effluents, for filtration of water,
algae and bacteria cultures, food stuff analyses, protein filtration, and radioimmunoassay of weak ß emitters.
• Recommended for gravimetric determination of airborne particulates, stack sampling, and absorption methods of air pollution monitoring.
