Grade 603 Standard Cellulose Extraction Thimble, 75x250mm, Thickness 2.5 mm, 25/Pk SKU: 10350287

Cellulose Extraction Thimble - 10350287

Efficient solid-liquid extraction for environmental compliance testing begins with a thimble that balances solvent permeability with the mechanical strength to contain fine-particle samples. Notably, Whatman applies over a century of filtration media expertise to this device, manufacturing under the quality standards that established its products as global laboratory references. Premium cotton linter fibers deliver the tensile strength and dimensional stability needed to withstand repeated solvent cycling without tearing or deformation. In effect, manufacturing quality controls ensure that each thimble meets the specifications required for validated extraction methods in environmental, food safety, and industrial laboratories.

Key Thimble Characteristics

• Cotton linter cellulose processed for low ash content minimizes background interference in gravimetric determinations and downstream chromatographic analysis.
• Controlled fiber density promotes efficient solvent permeation while retaining solid sample material within the thimble body during repeated extraction cycles.
• 75 mm ID configuration matched to standard extractor dimensions for reliable fit and consistent solvent flow dynamics.
• Seamless cylindrical construction with a closed bottom provides secure sample containment throughout extended Soxhlet extraction cycles without risk of sample loss.
• Low ash content supports accurate weight-based analytical determinations where thimble-derived residues could compromise measurement precision.

When your extraction results need to withstand regulatory scrutiny, the quality of your consumables matters as much as the quality of your technique. Under these conditions, mechanical durability through extended solvent contact gives your laboratory confidence that sample containment remains intact throughout multi-hour extraction procedures. Choose Whatman products to ensure that your filtration step meets the quality expectations established by one of the most recognized names in laboratory science.
