Glass Extraction Thimble, Grade 603G, 1 mm Thick, 19x90mm (25 pcs) SKU: 10371007

Glass Fiber (GF) Extraction Thimble - 10371007

Critical environmental monitoring protocols for particulate collection in hot gas streams require an extraction medium that maintains its retention characteristics at elevated operating temperatures. Moreover, Whatman applies over a century of filtration media expertise to this device, manufacturing under the quality standards that established its products as global laboratory references. Inert glass microfiber composition introduces no organic extractable background, ensuring that analytical results reflect sample content rather than thimble contribution. Consistent manufacturing quality across production lots supports reproducible analytical results and reliable method validation for regulated laboratory environments.

Key Thimble Characteristics

• Glass microfiber architecture captures fine particulate material through depth filtration, providing exceptional particle retention for demanding analytical matrices.
• Rated at 0.8 nominal particle retention for reliable sample containment during Soxhlet and automated solvent extraction procedures.
• Inert glass construction contributes no organic extractable background, supporting analytical methods where thimble-derived contamination would compromise results.
• Borosilicate glass maintains dimensional stability through repeated thermal cycling between ambient conditions and elevated pre-conditioning temperatures.
• High-purity glass microfiber construction supports trace-level analytical methods with stringent background contamination requirements.

Your analytical confidence starts with an extraction thimble that performs consistently from the first sample to the last in every batch. For applications like these, ultra-low organic background and furnace pre-conditioning capability ensure your trace-level analytical results are free from thimble-derived contamination artifacts. Choose Whatman products to ensure that your filtration step meets the quality expectations established by one of the most recognized names in laboratory science.
