Filter up to one liter with one device; filtration area is 16 cm2. Filter devices can be used in conjunction with a syringe or connected in-line (6 to 10 mm hose) via stepped hose Barbs. Autoclavable, a high-purity polypropylene housing maintains sample purity. Hold up volume with air Purge is less than 0.1 ml. Maximum operating pressure is 60 psi (4.1 bar). filters with PTFE membrane are ideal for chemically aggressive solutions, reagents, and organic solvents. Use as protective vents or for in-line filtration and isolation applications. Versatile and cost-effective filters for large-volume samples filter 29700-76 features a polypropylene prefilter for use with heavily contaminated samples

These GF/A glass microfiber filters offer 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, foodstuff analyses, protein filtration and radioimmunoassay of weak ? emitters. Recommended for gravimetric determination of airborne particulates, stack sampling and absorption methods of air pollution monitoring. Retention: 1.6?m. Diameter: 3.7cm. 100/Pack. Whatman #: 1820-037.

These GF/B glass microfiber filters are three times thicker than Whatman GF/A with higher wet strength and significantly increased loading capacity. Combines fine particle retention with good flow rate. Particularly useful where liquid clarification or solids quantification is required for heavily loaded fine particulate suspensions. Can be used as a finely retentive membrane prefilter. Used in LSC techniques where high loading capacity is required. Retention: 1.0?m. Diameter: 4.7cm. 100/Pack. Whatman #: 1821-047.
