Glass Extraction Thimble (w/out binder) 30x80mm (25 pcs) SKU: 2811-308

Glass Fiber (GF) Extraction Thimble - 2811-308

Extraction workflows involving aggressive solvents or elevated temperatures require a thimble constructed from chemically inert, thermally stable borosilicate glass. Whatman manufactures this device with the same process controls applied across its filtration portfolio, ensuring rated performance is verified at the production lot level. Borosilicate glass construction withstands thermal cycling between ambient and 500°C without dimensional change, supporting reproducible gravimetric determinations. Consistent manufacturing quality across production lots supports reproducible analytical results and reliable method validation for regulated laboratory environments.

Key Thimble Characteristics

• Inert glass composition introduces no organic extractable background, ensuring analytical results reflect true sample content rather than thimble-derived contamination.
• Suitable for direct use in hot gas sampling applications where the thimble serves as both the particulate collection medium and the extraction vessel.
• Temperature tolerance enables muffle furnace pre-conditioning to establish a clean analytical baseline before beginning the extraction procedure.
• Seamless glass microfiber construction with uniform wall geometry ensures predictable solvent distribution and reproducible extraction performance across all thimble surfaces.
• Glass microfiber architecture captures fine particulate material through depth filtration, providing exceptional particle retention for demanding analytical matrices.

When your extraction results need to withstand regulatory scrutiny, the quality of your consumables matters as much as the quality of your technique. In response, temperature stability through repeated thermal cycling supports your pre-conditioning and hot gas sampling workflows with consistent dimensional integrity and retention performance. Integrate Whatman filtration into your protocols to benefit from the brand recognition, lot documentation, and performance history that analytical laboratories trust worldwide.
