Grade 603 Standard Cellulose Extraction Thimble, 22x60mm, Thickness 2.0mm, 25/Pk SKU: 10350306

Cellulose Extraction Thimble - 10350306

Validated analytical methods for fat determination and residue screening specify extraction thimbles that deliver traceable quality and reproducible retention from lot to lot. As a Whatman product, this device carries the brand recognition and documented performance history that supports specification in standardized analytical methods. Seamless cellulose construction with a smooth interior surface minimizes sample adhesion and promotes complete recovery of extracted analytes from the thimble walls. To this end, optimized fiber density and wall construction deliver the balance of solvent throughput and sample retention that efficient extraction workflows demand.

Key Thimble Characteristics

• Seamless cylindrical construction with a closed bottom provides secure sample containment throughout extended Soxhlet extraction cycles without risk of sample loss.
• Temperature resistance to 120 ensures reliable thimble performance across the full range of compatible extraction and pre-conditioning protocols.
• Cellulose fiber construction provides a cost-effective extraction medium for high-volume laboratories processing large numbers of routine fat, oil, and residue samples.
• Dimensional precision matched to standard Soxhlet apparatus ensures proper clearance within the extractor body for unobstructed solvent siphoning.
• Low ash content supports accurate weight-based analytical determinations where thimble-derived residues could compromise measurement precision.

Your analytical confidence starts with an extraction thimble that performs consistently from the first sample to the last in every batch. To that end, 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.
