Cellulose Extraction Thimbles, 29x100mm ID/Height, 1.5mm Wall, High-Purity Cotton Linter, 25/Pk SKU: LE-CT5-017

Featuring high-purity cellulose fiber technology delivering exceptional mechanical strength and consistent retention for demanding Soxhlet extraction applications. These 29mm inner diameter by 100mm height thimbles are constructed from high-quality alpha cellulose cotton linter with precisely controlled 1.5mm wall thickness ensuring optimal structural integrity throughout extended extraction cycles. Maximum operating temperature of 120°C provides reliable performance for continuous solvent reflux operations in automated extraction systems.

Key Cellulose Fiber Characteristics

• High-quality cellulose construction delivers excellent mechanical strength and retention preventing sample loss during vigorous siphoning cycles
• Binderless cotton linter composition eliminates contamination sources while maintaining chemical purity for analytical protocols
• High purity material gives reliable and reproducible analytical results essential for quantitative determinations
• Neutral and fat-free construction prevents interference with lipid extraction and gravimetric analysis
• Hydrophilic surface chemistry optimizes solvent wetting and penetration for complete analyte recovery

Key Construction Characteristics

• Consistent 1.5mm wall thickness performs satisfactorily in applications requiring either single or double wall thickness specifications
• Very accurate dimensions for use in automatic extraction systems with exact matching to thimble holders ensuring optimum fit
• 29mm inner diameter accommodates standard sample volumes while maintaining proper solvent-to-sample ratios for extraction efficiency
• 100mm height design fits most commercial Soxhlet extractors including automated units and manual apparatus configurations
• Extraction thimble drains freely for the duration of the extraction period preventing solvent accumulation and maintaining continuous flow

These thimbles support AOAC Method 920.39 (Ether Extract) involving Soxhlet extraction using petroleum ether or diethyl ether for crude fat determination in food matrices. Applications include analysis of pesticide residues, determination of oil/fat content of foods, and analysis of oil and grease in solid wastes, delivering validated performance for environmental monitoring and food safety testing. Reference method compatibility with official methods of United States Environmental Protection Agency (US EPA) and The Association of Official Analytical Chemists (AOAC) transforms these thimbles into certified-grade analytical consumables for your most demanding extraction applications requiring both precision and regulatory compliance.
