VWR® Grade 696 Glass Fiber Filters

Choose VWR® Grade 696 Glass Fiber Filters for a fast, reliable, and high-capacity solution for all your demanding filtration needs.

Features:

• The binder-free construction ensures consistent, low-background results, making Grade 696 specifically recommended for monitoring sensitive pollutants like mercury where high extractables could compromise data
• Specifically designed for filtering seawater particulates and suspended solids due to its high resistance to aggressive saline environments
• The deep, three-dimensional matrix of glass fibers allows the filter to process significantly more sample volume before clogging compared to traditional cellulose papers
• Widely utilized in Radioimmunoassay (RIA) procedures and for the efficient harvesting of lymphocytes and other cell cultures
• Fast flow rates significantly reduce filtration time, even when handling viscous or particulate-heavy samples

Application & Care Guidelines:

• Handling: Glass fiber filters are delicate. Always use flat-tipped forceps to handle the edges to prevent tearing or compromising the fiber matrix
• Vacuum Filtration: For best results, use with a vacuum filtration setup. Ensure the filter is centered and slightly wetted with a small amount of ultra-pure water or buffer before applying full vacuum to create an even seal
• Pre-Cleaning: For trace-level analysis (e.g., heavy metals), it is recommended to pre-rinse the filter with a dilute acid or the sample solvent to remove any potential trace atmospheric contaminants
