Grade 603 Standard Cellulose Extraction Thimble, 25x80mm, Thickness 1.5mm, 25/Pk SKU: 10350217

Cellulose Extraction Thimble - 10350217

Validated analytical methods for fat determination and residue screening specify extraction thimbles that deliver traceable quality and reproducible retention from lot to lot. With a commitment to quality, manufactured by Whatman under Cytiva's quality infrastructure, this device benefits from a filtration heritage that spans laboratory, environmental, and industrial applications. Cotton linter cellulose processed under controlled conditions delivers the fiber purity and structural uniformity that validated extraction methods require. Consistent retention characteristics and dimensional precision ensure dependable performance from the first thimble in the pack to the last.

Key Thimble Characteristics

• Cellulose fiber matrix enables rapid solvent wetting and efficient permeation without pre-conditioning steps, reducing total extraction preparation time.
• Dimensional tolerances matched to DIN and BS standard Soxhlet extractors ensure proper fit with 1 to 2 mm clearance within the apparatus body.
• Controlled fiber density promotes efficient solvent permeation while retaining solid sample material within the thimble body during repeated extraction cycles.
• Mechanical strength sufficient to maintain structural integrity when saturated with solvent and loaded with sample, even during extended multi-hour extraction cycles.
• Cotton linter cellulose processed for low ash content minimizes background interference in gravimetric determinations and downstream chromatographic analysis.

When validated methods require documented consumable performance, your extraction thimble must deliver traceable quality and reproducible results. To that end, compatibility with the full range of common extraction solvents provides your laboratory with a single thimble solution for diverse routine analytical methods. Choose Whatman products to ensure that your filtration step meets the quality expectations established by one of the most recognized names in laboratory science.
