Grade 603 Standard Cellulose Extraction Thimble, 35x150mm, Thickness 1.5mm, 25/Pk SKU: 10350255

Cellulose Extraction Thimble - 10350255

Quantitative recovery of extractable organic compounds from soil, food, and industrial matrices depends on a thimble that retains the sample while allowing unrestricted solvent circulation. Furthermore, 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. Seamless cellulose construction with a smooth interior surface minimizes sample adhesion and promotes complete recovery of extracted analytes from the thimble walls. Optimized fiber density and wall construction deliver the balance of solvent throughput and sample retention that efficient extraction workflows demand.

Key Thimble Characteristics

• Mechanical strength maintained throughout solvent saturation supports extended extraction cycles without risk of thimble deformation or tearing.
• Cotton linter cellulose processed for low ash content minimizes background interference in gravimetric determinations and downstream chromatographic analysis.
• Dimensional precision matched to standard Soxhlet apparatus ensures proper clearance within the extractor body for unobstructed solvent siphoning.
• Uniform fiber density throughout the thimble wall prevents solvent channeling and ensures complete sample contact during each extraction cycle.
• Mechanical strength sufficient to maintain structural integrity when saturated with solvent and loaded with sample, even during extended multi-hour extraction cycles.

Selecting an extraction thimble matched to your solvent system, temperature requirements, and apparatus dimensions ensures optimal analytical performance from the start. Mechanical durability through extended solvent contact gives your laboratory confidence that sample containment remains intact throughout multi-hour extraction procedures. When your methods require a filtration product with established performance credentials, Whatman delivers the documented quality your laboratory depends on.
