Grade 603 Standard Cellulose Extraction Thimble, 40x85mm, Thickness 1.5mm, 25/Pk SKU: 10350261

Cellulose Extraction Thimble - 10350261

Automated and manual Soxhlet systems require extraction thimbles sized precisely to the apparatus, ensuring optimal solvent flow and complete sample contact throughout the extraction cycle. As a Whatman product, this device carries the brand recognition and documented performance history that supports specification in standardized analytical methods. High-purity alpha cellulose cotton linter construction provides excellent mechanical strength and sample retention while maintaining low extractable background levels. By design, engineered sample containment and solvent permeability work together to maximize extraction efficiency while protecting the integrity of downstream analytical determinations.

Key Thimble Characteristics

• Closed-bottom design eliminates the need for secondary containment, allowing direct loading of powdered, granular, and semi-solid sample materials.
• Smooth interior surface minimizes sample adhesion to the thimble wall, promoting quantitative transfer of extracted analytes to the collection flask.
• High-purity alpha cellulose cotton linter construction delivers excellent mechanical strength and low extractable background for demanding analytical extraction workflows.
• Natural cellulose fiber composition enables rapid solvent wetting without pre-conditioning, reducing setup time for routine extraction procedures.
• Smooth interior wall surface promotes complete analyte transfer to the collection flask, minimizing sample loss from wall adhesion.

Your extraction method is only as reliable as the weakest component in the system, and the thimble is where sample integrity begins. To meet this need, pure cotton linter composition and smooth interior surfaces protect your downstream analytical instruments from particulate carryover and extractable contamination. Choose Whatman products to ensure that your filtration step meets the quality expectations established by one of the most recognized names in laboratory science.
