Glass Extraction Thimble, Grade 603G, 1.5mm Thick, 35x150mm (25 pcs) SKU: 10371055

Glass Fiber (GF) Extraction Thimble - 10371055

Trace-level gravimetric analysis in environmental and industrial settings requires an extraction thimble that contributes no organic background to the analytical determination. Built on proven expertise, manufactured by Whatman under Cytiva's quality infrastructure, this device benefits from a filtration heritage that spans laboratory, environmental, and industrial applications. Temperature resistance to 500°C allows direct use in hot gas sampling applications and furnace pre-treatment protocols requiring sustained high-temperature exposure. By design, predictable thimble-to-thimble consistency eliminates a common source of analytical variability, allowing laboratory results to reflect sample differences rather than consumable quality.

Key Thimble Characteristics

• Temperature tolerance enables muffle furnace pre-conditioning to establish a clean analytical baseline before beginning the extraction procedure.
• 35 mm inner diameter sized for precise fit within standard Soxhlet and automated extraction apparatus with appropriate wall clearance.
• High-purity glass composition supports trace-level environmental and industrial analytical methods with stringent background contamination requirements.
• Sustained thermal stability allows direct use in hot gas sampling applications where the thimble functions as both the collection medium and the extraction vessel.
• Borosilicate glass microfiber construction provides broad chemical resistance to acids, bases, and aggressive organic solvents encountered in demanding extraction workflows.

When validated methods require documented consumable performance, your extraction thimble must deliver traceable quality and reproducible results. In practice, glass microfiber durability and chemical resistance reduce your risk of thimble failure during extended extractions with aggressive solvent systems. Choose Whatman products to ensure that your filtration step meets the quality expectations established by one of the most recognized names in laboratory science.
