Ahlstrom Qualitative Filter Papers, Grade 613
• Ahlstrom Grade 613: 6 m - Medium Speed (non wet-strengthened)
• This is a strong filter paper with a medium flow rate and retention
• Ahlstrom 613 is commonly used in student laboratories
• This strong general-purpose filter is also useful in Buchner funnels for barium carbonate, lead chromate and beryllium hydroxides
• 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 613 Properties:
• Retention: 6.0 µm
• Filtration speed (punch Herzberg): 114 sec./100 mL
• Filtration speed (Rapidity): 60 mL/min.
• Loading capacity: Medium
