Ahlstrom Qualitative Filter Papers, Grade 601
• Ahlstrom Grade 601: 2.5 m - Medium Speed (non wet-strengthened)
• This grade covers a wide range of laboratory applications and is used for clarifying liquids and for rapid filtration of coarser precipitates such as lead sulfate, lead chromate, calcium oxalate, calcium carbonate, aluminum phosphate, barium carbonate and beryllium hydroxide
• Ahlstrom 601 can be found in soil analysis, seed testing and in air pollution to collect dust-laden air and is also commonly used in the food industry to separate foodstuffs from associated liquid or extracting liquid
• Standard Grades (Non Wet-Strengthened)
• Standard qualitative filter papers are suitable for quadrant folded or gravity flow applications
• 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 not pose a problem when they are used in routine quadrant folded applications
• Ahlstrom does not recommend these grades for use in vacuum work or when wet handling is required
• Qualitative analysis
• Low ash content 0.06%
• > 95% super refined -cellulose and linter fibers
• Untreated
• Consistent performance
• Custom cut
• Bulk packaging
Grade 601 Properties:
• Retention: 2.5 µm
• Filtration speed (punch Herzberg): 124 sec./100 mL
• Filtration speed (Rapidity): 55 mL/min.
• Loading capacity: Medium
Image(s) are representative of the product group and not necessarily the individual product.
