Ahlstrom 6170-1100 Qualitative Filter Paper 11cm Diameter 35 Micron Fast Flow...

Description

Ahlstrom 6170-1100 Qualitative Filter Paper, 11cm Diameter, 35 Micron, Fast Flow, Grade 617 (Pack of 50)
Qualitative filter papers are often used in routine separation work that still requires high purity and consistent performance
Qualitative grades consist of greater than 95 percent super refined a-cellulose and linter fibers
Standard qualitative filter papers are suitable for quadrant folded or gravity flow applications
This is an extremely fast filtering grade and has a larger particle retention
Ahlstrom 617, a thicker filter paper with higher loading capacity, is used for rapid filtration of coarse particles and gelatinous precipitates such as in oils and resin solutions
Ahlstrom's qualitative grades of filter paper are, by definition, recommended for use in analytical methods, which determine or identify particulate constituents of a mixture irrespective of the amount present. Ahlstrom offers a complete range of low ash filter papers for general laboratory work that provides you with the correct combination of particle retention, filtration speed, loading capacity and wet-strength. Qualitative analysis, low ash content 0.06 percent, untreated, consistent performance, wet-strengthened grades, custom cut. These grades contain a high level of alpha-cellulose that provides high purity but will weaken when wet. The inherent strength of standard (untreated) grades does pose a problem when they are used in routine quadrant folded applications. We do recommend these grades for use in vacuum work or when wet handling is required. Ahlstrom 617 is also found in construction product testing and is used by students to retain large flocculents and precipitates.
