GVS Filter, Disk, CA, 0.45µm, 13mm, 100/PK 1215533

Glass Microfiber filter disks made of borosilicate glass fibers without binders for laboratory filtration and sample clarification. These 47 mm, binder-free disks provide 0.7 µm particulate retention and are intended for fine retention tasks such as pre-filtration for HPLC, suspended solids analysis in water and industrial wastes, cell harvesting, protein filtrations and aqueous clarification and monitoring.

Key Features:

• Diameter: 47 mm
• Filter media: Glass microfiber (borosilicate), binder-free
• Pore size (retention): 0.7 µm
• Box quantity: 100 discs per pack
• Thickness: 0.4 mm
• Retention (DOP): 99.998%
• Filtration time for distilled water: 66 seconds

Advantages:

• Very fine retention performance suitable for HPLC solvent/sample prefiltration and analytical determinations.
• Binder-free construction avoids binder extractables, making it appropriate for solvent filtration and gravimetric analyses.
• Biologically inert and temperature-resistant, providing chemical resistance and compatibility with common laboratory treatments.
• High particle capture efficiency (DOP 99.998%) with medium flow characteristics for reliable sample clarification.
