High Purity Glass Soxhlet Extraction Thimble, 30x100mm (25 pcs) SKU: 2814-300

Glass Fiber (GF) Extraction Thimble - 2814-300

Environmental compliance methods for analyzing hot flue gases, acidic emissions, and industrial exhaust streams specify extraction media rated for sustained high-temperature exposure. 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. Pure borosilicate glass composition provides broad chemical resistance to aggressive solvents, strong acids, and oxidizing agents encountered in demanding extraction workflows. Precise dimensional tolerances and uniform construction support seamless integration into both manual Soxhlet apparatus and automated extraction platforms.

Key Thimble Characteristics

• Overall length of 100 mm accommodates the sample volume requirements of common analytical extraction methods.
• Glass microfiber depth structure provides high particulate loading capacity while maintaining consistent solvent flow throughout the extraction cycle.
• Precision 30 mm internal diameter ensures optimal sample capacity while maintaining the clearance required for efficient solvent siphoning.
• Borosilicate glass composition maintains dimensional stability across thermal cycling between ambient temperature and furnace pre-conditioning conditions without structural degradation.
• 0.8 nominal retention captures fine particulate sample material while maintaining the solvent permeability required for efficient extraction.

Your analytical confidence starts with an extraction thimble that performs consistently from the first sample to the last in every batch. Inert glass composition eliminates the organic extractable background that would compromise your sensitive detection methods at trace concentration levels. Standardize on Whatman filtration to bring the consistency and documented performance of a century-old filtration brand to your laboratory workflows.
