Ahlstrom - 0950-2400 - FLTR PAPER 95 SIZE 24 CM (Pack of 100)

ITEM #: 3412636
Ahlstrom manufactures a series of e x tremely high purity, acid washed filter papers designed for use in analytical and gravimetric analysis. The quantitative grades are manufactured from top quality cotton linters using ultra-pure, reverse-osmosis water and are further treated with dilute acid to remove any remaining organic and inorganic impurities. All quantitative grades are manufactured in a strictly controlled environment that ensures high uniformity and high purity from filter to filter.

• Quantitative analysis
• Low ash content 0.007% (Acid-wash treated)
• High wet-strength
• Consistent performance
• Custom cut
• Bulk packaging

Hardened Ashless Grades (Ash 0.006%)
These specially treated hardened ashless grades are available for critical quantitative analytical techniques requiring increased wet-strength and handling capacity. These high purity filter papers have a tough, smooth surface free of loose fibers and are ideal for collecting wet precipitates. Each grade offers a convenient combination of particle retention and flow rate and are generally used because of their high chemical resistance to strong acid and alkali.
Ahlstrom 95: 1.5µm - Slow Speed
This is an e x tremely fine retention filter for critical gravimetric analysis and metal determination of very fine particles such as barium and lead sulfates, stannic and nickel sulfide, calcium o x alate and calcium fluoride.
Mining Laboratory Applications:
ASTM E278-01 Determination of Phosphorus in Iron Ores
This test has two filtration stages. The first stage can use a qualitative filter, such as grade 631. The second stage requires a hardened, ashless, fine filter. Grade 95 is recommended.
ASTM E314-10 Determination of Manganese in Iron Ore
The precipitate from this procedure is very fine and is ashed for a quantitative analysis. The procedure also requires a strong filter when wet. Grade 95 is a perfect selection for this procedure.
STM4500-SO4 2-.C Total Sulfate in Water: Gravimetric Method
The gravimetric method with ignition of residue calls for an acid-washed, ashless, hard-finish paper retentive enough for find precipitate. These requirements are met by Grade 95.
Construction Laboratory Applications:
ASTM D5891-02 Fluid Loss of Clay Component of Geosynthetic Clay Liners
The clay slurry is filtered through a fine hardened filter. The amount of time to e x tract a certain volume of water from the sample is determined. Grade 95 is used for this test.
