Glass Extraction Thimble, Grade 603G, 1 mm Thick, 10x38mm (25 pcs) SKU: 10371103

Glass Fiber (GF) Extraction Thimble - 10371103

Trace-level gravimetric analysis in environmental and industrial settings requires an extraction thimble that contributes no organic background to the analytical determination. As a Whatman product, this device carries the brand recognition and documented performance history that supports specification in standardized analytical methods. Borosilicate glass composition delivers inherent chemical stability across the full pH range, supporting extraction workflows involving acidic, basic, and neutral solvent systems. In turn, documented manufacturing consistency ensures that extraction results reflect true sample composition rather than variability introduced by the consumable.

Key Thimble Characteristics

• Sustained thermal stability allows direct use in hot gas sampling applications where the thimble functions as both the collection medium and the extraction vessel.
• Borosilicate glass microfiber composition provides chemical resistance to strong acids, bases, and aggressive organic solvents encountered in demanding extraction workflows.
• Temperature tolerance up to 500°C enables muffle furnace pre-conditioning to burn off trace organic residues before the extraction cycle begins.
• Borosilicate glass composition maintains dimensional stability across thermal cycling between ambient temperature and furnace pre-conditioning conditions without structural degradation.
• Glass fiber matrix architecture captures fine particulate material through depth filtration, providing exceptional retention performance for demanding analytical matrices.

Your extraction workflow depends on a thimble that maintains its structural integrity and retention characteristics throughout the entire analytical procedure. For exactly this reason, inert glass composition eliminates the organic extractable background that would compromise your sensitive detection methods at trace concentration levels. Choose Whatman products to ensure that your filtration step meets the quality expectations established by one of the most recognized names in laboratory science.
