Ahlstrom Binderless Glass Microfiber Filters, Grade 141
• Grade 141: 3.1 µm - Fast speed
• This grade offers better filtration speed and a higher loading capacity than an analytical filter paper of similar particle retention
• Grade 141 is particularly recommended for pre-filtration of membrane filters and is also used in combination with Grade 121 as a high efficient protective and retentive grade density pre-filter for membrane filters
• Standard glass microfiber filters contain no binders or other additives that may cause interference to sensitive enzymatic or other chemical reactions
• The unique characteristics of glass microfiber filters make its use particularly advantageous to laboratory filtration by enabling fast filtration of large volumes and difficult solutions without premature clogging
• Qualitative analysis
• Laboratory analysis
• 100% pure borosilicate glass
• Rapid flow rate
• Fine particle retention
• High loading capacity
• Chemical and thermal resistance (up to 500°C)
• Long shelf life
• Brilliant white color reflecting more than 96% of visible light
• Custom cut
Grade 141 Properties:
• Retention: 3.1 µm
• Filtration speed (Herzberg): 19 sec./100 mL
• Filtration speed (Rapidity): 350 mL/min.
• Loading capacity: Very High
