LARK LGF/C filters offer fine particle retention, good flow rate, and loading capacity. LGF/C filter papers support total suspended solids analysis. Widely used by Water Boards & industries for wastewater testing. LGF/C are used for high-efficiency general-purpose laboratory filtration, including water pollution monitoring of effluents, filtration of water, algae, and bacteria cultures, foodstuff analyses, protein filtration, and radioimmunoassay of weak ß emitters. Offers fine particle retention and a high flow rate, as well as good loading capacity. Used for high-efficiency general purpose laboratory filtration, including water pollution monitoring of effluents, filtration of water, algae and bacteria cultures, foodstuff 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.
