Cellulose Soxhlet Extraction Thimble, Single 1 mm Wall, 19x90mm (25 pcs) SKU: 2800-199

Cellulose Extraction Thimble - 2800-199

Routine analytical extraction of pesticide residues, fat content, and organic pollutants requires a thimble that delivers reliable retention without interfering with downstream detection. 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. High-purity cellulose construction balances the permeability needed for efficient solvent circulation with the mechanical integrity to retain fine particulate samples. Because of this, uniform construction quality delivers the reproducible performance that standardized extraction methods require for defensible analytical reporting.

Key Thimble Characteristics

• 10 nominal particle retention ensures effective containment of fine sample material throughout the extraction process.
• Seamless closed-bottom construction securely contains powdered, granular, and semi-solid sample materials without secondary containment requirements.
• Uniform fiber density throughout the thimble wall prevents solvent channeling and ensures complete sample contact during each extraction cycle.
• High-purity alpha cellulose cotton linter construction delivers excellent mechanical strength and low extractable background for demanding analytical extraction workflows.
• Low ash content supports accurate weight-based analytical determinations where thimble-derived residues could compromise measurement precision.

Reproducible extraction performance across production lots means your laboratory can focus on interpreting data rather than troubleshooting consumable variability. Precise dimensional fit within standard Soxhlet apparatus ensures efficient solvent cycling through your samples, maximizing analyte recovery in every extraction run. Standardize on Whatman filtration to bring the consistency and documented performance of a century-old filtration brand to your laboratory workflows.
