Grade B Glass Fiber Filter Paper 1.0um, 24mm, Nonsterile, 50/Pk SKU: EF19023

Glass Fiber (GF) Filter Paper - EF19023

Air particulate sampling for gravimetric mass determination demands a filter medium with low tare weight variability and thermal stability through weighing procedures. Binderless construction eliminates organic and resin-based additives that would contribute background contamination to sensitive downstream analytical methods. From fiber selection through final inspection, the manufacturing process ensures every sheet meets the performance specifications of its grade.

Key Filter Paper Characteristics

• Hydrophilic glass surface wets spontaneously on contact with aqueous solutions, requiring no pre-conditioning before sample filtration.
• Binderless glass fiber construction delivers ultra-low blank values for gravimetric, thermal, and trace analytical methods requiring clean filter backgrounds.
• Depth filtration captures particles throughout the fiber matrix rather than at the surface, maximizing total loading capacity before flow restriction.
• High void volume within the randomly oriented fiber matrix sustains flow rates through heavy particulate loads that would blind surface-capture filters.
• Inorganic glass matrix withstands temperatures exceeding 500 degrees C, supporting ignition-based gravimetric methods without filter decomposition.

Scaling your method from development to routine production requires paper consistency at every lot, and the specifications above provide that assurance. To support this, binderless borosilicate construction eliminates the organic extractables that would compromise your downstream chromatographic or spectroscopic analysis. 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.
