Cellulose Soxhlet Extraction Thimble, Single 1 mm Wall, 28x120mm (25 pcs) SKU: 2800-282

Cellulose Extraction Thimble - 2800-282

Gravimetric fat determination and pesticide residue workflows require an extraction thimble that combines high sample retention with minimal background contamination. 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. By design, reliable mechanical performance and controlled permeability support efficient analyte recovery across the full range of common laboratory extraction protocols.

Key Thimble Characteristics

• Cellulose fiber matrix enables rapid solvent wetting and efficient permeation without pre-conditioning steps, reducing total extraction preparation time.
• Uniform wall construction maintains consistent solvent flow distribution across the thimble surface, preventing channeling that could reduce extraction efficiency.
• Dimensional precision matched to standard Soxhlet apparatus ensures proper clearance within the extractor body for unobstructed solvent siphoning.
• Compatible with standard Soxhlet extraction solvents including hexane, petroleum ether, dichloromethane, diethyl ether, and chloroform.
• Alpha cellulose cotton linter fiber composition provides high purity with minimal extractable residues for accurate gravimetric and chromatographic analysis.

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.
