Glass Extraction Thimble, Grade 603G, 1.5mm Thick, 33x118mm (25 pcs) SKU: 10371045

Glass Fiber (GF) Extraction Thimble - 10371045

Biochemical extraction and environmental analysis involving chlorinated solvents, strong acids, or oxidizing agents require a chemically inert extraction medium. In addition, Whatman's expertise in cellulose, glass fiber, and polymeric membrane production informs the material selection and quality controls applied to this device. Borosilicate glass construction withstands thermal cycling between ambient and 500°C without dimensional change, supporting reproducible gravimetric determinations. In combination, manufacturing quality controls ensure that each thimble meets the specifications required for validated extraction methods in environmental, food safety, and industrial laboratories.

Key Thimble Characteristics

• Chemical stability across the full pH range supports extraction workflows involving acidic, neutral, and alkaline solvent systems without fiber degradation.
• Seamless glass microfiber construction with uniform wall geometry ensures predictable solvent distribution and reproducible extraction performance across all thimble surfaces.
• Borosilicate composition delivers inherent resistance to biological degradation, eliminating storage and shelf-life concerns in long-term laboratory inventory.
• Glass microfiber depth structure provides high particulate loading capacity while maintaining consistent solvent flow throughout the extraction cycle.
• 33 mm ID configuration matched to standard extractor dimensions for reliable fit and consistent solvent flow dynamics.

Your analytical confidence starts with an extraction thimble that performs consistently from the first sample to the last in every batch. To that end, chemical inertness across the full pH range means your extraction protocols involving aggressive acids, bases, and oxidizing solvents proceed without risk of media degradation. Standardize on Whatman filtration to bring the consistency and documented performance of a century-old filtration brand to your laboratory workflows.
