High Purity Glass Soxhlet Extraction Thimble, TapeRed, 25x90mm (25 pcs) SKU: 2814-259

Glass Fiber (GF) Extraction Thimble - 2814-259

Analytical methods requiring muffle furnace pre-conditioning of the extraction vessel demand a thermally stable medium rated for sustained high-temperature exposure. Furthermore, produced under Whatman's established manufacturing platform, this device reflects the consistency and lot-level documentation that analytical laboratories require. Borosilicate glass composition delivers inherent chemical stability across the full pH range, supporting extraction workflows involving acidic, basic, and neutral solvent systems. To this end, reliable mechanical performance and controlled permeability support efficient analyte recovery across the full range of common laboratory extraction protocols.

Key Thimble Characteristics

• Inert glass construction contributes no organic extractable background, supporting analytical methods where thimble-derived contamination would compromise results.
• Glass fiber matrix architecture captures fine particulate material through depth filtration, providing exceptional retention performance for demanding analytical matrices.
• High-purity glass microfiber construction supports trace-level analytical methods with stringent background contamination requirements.
• Chemical stability across the full pH range supports extraction workflows involving acidic, neutral, and alkaline solvent systems without fiber degradation.
• 25 mm inner diameter sized for precise fit within standard Soxhlet and automated extraction apparatus with appropriate wall clearance.

Reliable sample containment and efficient solvent permeation ensure that your extraction cycles deliver quantitative analyte recovery every time. In these cases, reliable performance in both Soxhlet extraction and direct hot gas sampling gives your laboratory a versatile high-temperature extraction medium for diverse analytical applications. Integrate Whatman filtration into your protocols to benefit from the brand recognition, lot documentation, and performance history that analytical laboratories trust worldwide.
