Ahlstrom Qualitative Filter Papers, Grade 610

• Ahlstrom Grade 610: 1.5 m - Slow Speed (non wet-strengthened)
• This grade is a slow flowing filter designed to retain fine particles encountered in qualitative analysis
• Ahlstrom 610 is widely used for water analysis, biological products and fine precipitates such as coldprecipitated barium sulfate
• Ahlstrom 610 is also used in Buchner funnels and to clarify cloudy suspensions

• 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 610 Properties:
• Retention: 1.5 µm
• Filtration speed (punch Herzberg): 1724 sec./100 mL
• Filtration speed (Rapidity): 4 mL/min.
• Loading capacity: Medium
