Grade 603 Standard Cellulose Extraction Thimble, 30x100mm, Thickness 1.5mm, 25/Pk SKU: 10350236

Cellulose Extraction Thimble - 10350236

Accurate solvent extraction of solid and semi-solid samples starts with a thimble engineered to deliver consistent mechanical strength across extended extraction cycles. Whatman's expertise in cellulose, glass fiber, and polymeric membrane production informs the material selection and quality controls applied to this device. High-purity alpha cellulose cotton linter construction provides excellent mechanical strength and sample retention while maintaining low extractable background levels. Because of this, optimized fiber density and wall construction deliver the balance of solvent throughput and sample retention that efficient extraction workflows demand.

Key Thimble Characteristics

• Alpha cellulose cotton linter fiber composition provides high purity with minimal extractable residues for accurate gravimetric and chromatographic analysis.
• 100 mm thimble length provides sufficient sample capacity while positioning correctly above the siphon tube in standard extraction apparatus.
• Cellulose construction provides a cost-effective sample containment solution for high-throughput laboratories processing large extraction batch volumes.
• Smooth interior wall surface promotes complete analyte transfer to the collection flask, minimizing sample loss from wall adhesion.
• Uniform wall construction maintains consistent solvent flow distribution across the thimble surface, preventing channeling that could reduce extraction efficiency.

Your extraction method is only as reliable as the weakest component in the system, and the thimble is where sample integrity begins. Pure cotton linter composition and smooth interior surfaces protect your downstream analytical instruments from particulate carryover and extractable contamination. Integrate Whatman filtration into your protocols to benefit from the brand recognition, lot documentation, and performance history that analytical laboratories trust worldwide.
