Grade C Glass Fiber Filter Paper 1.2um, 24mm, Nonsterile, 100/Pk SKU: EF19039

Glass Fiber (GF) Filter Paper - EF19039

Clarifying biological fluids and cell culture harvests requires depth filtration capacity that cellulose papers and surface-capture membranes cannot match. Binderless construction eliminates organic and resin-based additives that would contribute background contamination to sensitive downstream analytical methods. In effect, consistent physical properties across the full sheet area support uniform filtration results in both gravity and vacuum applications.

Key Filter Paper Characteristics

• Pure borosilicate glass provides ultra-low blank values for trace analytical methods sensitive to organic or inorganic background contamination.
• Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.
• Inorganic glass matrix withstands temperatures exceeding 500 degrees C, supporting ignition-based gravimetric methods without filter decomposition.
• Thermal stability exceeding 500 degrees C supports ignition-based gravimetric methods without filter decomposition or residue artifacts.
• Pure borosilicate glass construction eliminates organic extractables that could interfere with downstream chromatographic or spectroscopic analysis.

Your sample preparation workflow benefits from a filter paper whose performance is defined, documented, and consistent from one purchase to the next. Specifically, thermal stability exceeding 500 degrees C supports the ignition step your gravimetric method requires without introducing filter decomposition artifacts. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

• Biological Clarification - Clears cell culture harvests and biological lysates of particulate debris before chromatographic purification.
• Suspended Solids Analysis - Captures particulates from water and wastewater samples for gravimetric TSS determination by standard methods.
• Gravimetric Air Monitoring - Thermal stability supports ignition-based mass determination of collected airborne particulate samples.
• Turbid Sample Processing - High loading capacity filters heavily particulate environmental and industrial samples without premature clogging.
• Chlorophyll Extraction - Concentrates algal cells from water column samples for chlorophyll measurement in aquatic quality assessment.
• Radioimmunoassay Harvesting - Binderless construction eliminates chemical interference during harvesting of bound radioactive tracers.
