High Purity Glass Soxhlet Extraction Thimble, 19x90mm (25 pcs) SKU: 2814-199

Glass Fiber (GF) Extraction Thimble - 2814-199

Biochemical extraction and environmental analysis involving chlorinated solvents, strong acids, or oxidizing agents require a chemically inert extraction medium. Manufactured by Whatman under Cytiva's quality infrastructure, this device benefits from a filtration heritage that spans laboratory, environmental, and industrial applications. High-purity borosilicate glass fiber construction eliminates organic contamination risk when processing chemically aggressive sample matrices. Because of this, consistent retention characteristics and dimensional precision ensure dependable performance from the first thimble in the pack to the last.

Key Thimble Characteristics

• Temperature tolerance up to 500°C enables muffle furnace pre-conditioning to burn off trace organic residues before the extraction cycle begins.
• Inert glass composition introduces no organic extractable background, ensuring analytical results reflect true sample content rather than thimble-derived contamination.
• Glass fiber matrix architecture captures fine particulate material through depth filtration, providing exceptional retention performance for demanding analytical matrices.
• 90 mm thimble length provides sufficient sample capacity while positioning correctly above the siphon tube in standard extraction apparatus.
• High-purity glass microfiber construction supports trace-level analytical methods with stringent background contamination requirements.

Your extraction method is only as reliable as the weakest component in the system, and the thimble is where sample integrity begins. In particular, chemical inertness across the full pH range means your extraction protocols involving aggressive acids, bases, and oxidizing solvents proceed without risk of media degradation. Integrate Whatman filtration into your protocols to benefit from the brand recognition, lot documentation, and performance history that analytical laboratories trust worldwide.
