Grade 603 Standard Cellulose Extraction Thimble, 44x230mm, Thickness 2.0mm, 25/Pk SKU: 10350275

Cellulose Extraction Thimble - 10350275

Standardized Soxhlet extraction methods for oil, grease, and organic compound analysis require a thimble that fits precisely and performs consistently across production lots. With a commitment to quality, 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. 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

• Smooth interior surface minimizes sample adhesion to the thimble wall, promoting quantitative transfer of extracted analytes to the collection flask.
• Pure cellulose composition ensures full compatibility with common Soxhlet extraction solvents including hexane, petroleum ether, dichloromethane, and diethyl ether.
• Seamless closed-bottom construction securely contains powdered, granular, and semi-solid sample materials without secondary containment requirements.
• Dimensional precision matched to standard Soxhlet apparatus ensures proper clearance within the extractor body for unobstructed solvent siphoning.
• Mechanical strength sufficient to maintain structural integrity when saturated with solvent and loaded with sample, even during extended multi-hour extraction cycles.

When your extraction results need to withstand regulatory scrutiny, the quality of your consumables matters as much as the quality of your technique. Compatibility with the full range of common extraction solvents provides your laboratory with a single thimble solution for diverse routine analytical methods. Standardize on Whatman filtration to bring the consistency and documented performance of a century-old filtration brand to your laboratory workflows.
