THIMBLE HPGF 53ID x 135MM L 25/Pk SKU: 2814-533

Glass Fiber (GF) Extraction Thimble - 2814-533

Precision analytical work at trace concentration levels demands an extraction thimble with ultra-low background extractables to prevent interference with sensitive detection methods. Produced under Whatman's established manufacturing platform, this device reflects the consistency and lot-level documentation that analytical laboratories require. Pure borosilicate glass composition provides broad chemical resistance to aggressive solvents, strong acids, and oxidizing agents encountered in demanding extraction workflows. 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

• Glass fiber matrix architecture captures fine particulate material through depth filtration, providing exceptional retention performance for demanding analytical matrices.
• Borosilicate glass microfiber composition provides chemical resistance to strong acids, bases, and aggressive organic solvents encountered in demanding extraction workflows.
• High-purity glass composition supports trace-level environmental and industrial analytical methods with stringent background contamination requirements.
• Borosilicate glass microfiber construction provides broad chemical resistance to acids, bases, and aggressive organic solvents encountered in demanding extraction workflows.
• Temperature resistance to 500 ensures reliable thimble performance across the full range of compatible extraction and pre-conditioning protocols.

Reproducible extraction performance across production lots means your laboratory can focus on interpreting data rather than troubleshooting consumable variability. In response, temperature stability through repeated thermal cycling supports your pre-conditioning and hot gas sampling workflows with consistent dimensional integrity and retention performance. Choose Whatman products to ensure that your filtration step meets the quality expectations established by one of the most recognized names in laboratory science.
