Glass Fiber (GF) Extraction Thimble - 2814-432
Trace-level gravimetric analysis in environmental and industrial settings requires an extraction thimble that contributes no organic background to the analytical determination. Notably, produced under Whatman's established manufacturing platform, this device reflects the consistency and lot-level documentation that analytical laboratories require. Seamless glass microfiber construction with consistent wall geometry ensures uniform solvent distribution and predictable extraction performance across the entire thimble surface. On this basis, precision-manufactured dimensions ensure optimal fit within standard extraction apparatus, promoting complete solvent contact and quantitative analyte recovery.
Key Thimble Characteristics
- 0.8 nominal retention captures fine particulate sample material while maintaining the solvent permeability required for efficient extraction.
- Borosilicate glass maintains dimensional stability through repeated thermal cycling between ambient conditions and elevated pre-conditioning temperatures.
- Chemical inertness across the full pH range supports extraction workflows involving acidic, neutral, and alkaline solvent systems without risk of fiber degradation.
- Glass microfiber depth structure provides high particulate loading capacity while maintaining consistent solvent flow characteristics throughout the extraction process.
- Borosilicate glass microfiber composition provides chemical resistance to strong acids, bases, and aggressive organic solvents encountered in demanding extraction workflows.
Your analytical confidence starts with an extraction thimble that performs consistently from the first sample to the last in every batch. To address this, 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.
