Grade B Glass Fiber Filter Paper 1.0um, 150mm, Nonsterile, 10/Pk SKU: EF19034

Glass Fiber (GF) Filter Paper - EF19034

Liquid scintillation counting and radioimmunoassay procedures need a binderless glass fiber substrate that introduces no chemical interference to sensitive detection methods. Hydrophilic glass surface wets immediately on contact with aqueous solutions, requiring no pre-conditioning before filtration begins. Consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.
• Thermal stability exceeding 500 degrees C supports ignition-based gravimetric methods without filter decomposition or residue artifacts.
• Chemically inert borosilicate composition resists acids, bases, and organic solvents across the full pH range without fiber degradation.
• High void volume within the randomly oriented fiber matrix sustains flow rates through heavy particulate loads that would blind surface-capture filters.
• Binderless glass fiber matrix eliminates organic extractables that would interfere with downstream chromatographic or spectroscopic determinations.

Maintaining accreditation requires documented traceability at every step, and the grade specifications above support your audit readiness. Under these conditions, chemical inertness across the full pH range means this filter handles the same aggressive sample matrices your analytical membranes process. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
