Ahlstrom AH51503200 Grade 515 Filter Paper for Laboratory Filtration (32 cm, Pack of 100)

FILTER PAPER GRADE #515, 32cm, (100)

32.00cm Grade 515 Fast Flow Pre-Pleated Filter Paper. Ahlstrom offers a full range of standard pleated grades that meet your needs from grades with rapid flow rates for filtration of viscous materials to grades with tight matrices for removal of fine precipitates. Ahlstrom's pre-pleated grades can save valuable time and maximize the efficiency of the laboratory filter system. Pleating improves the effective surface area increasing flow rate and loading capacity thus decreasing filtration time.
