Cellulose Soxhlet Extraction Thimble, Single 1 mm Wall, 25x80mm (25 pcs) SKU: 2800-258

Cellulose Extraction Thimble - 2800-258

Accurate solvent extraction of solid and semi-solid samples starts with a thimble engineered to deliver consistent mechanical strength across extended extraction cycles. Whatman's expertise in cellulose, glass fiber, and polymeric membrane production informs the material selection and quality controls applied to this device. Cellulose fiber construction rated to 120°C provides reliable performance across the full range of common Soxhlet extraction solvents and operating conditions. Consistent retention characteristics and dimensional precision ensure dependable performance from the first thimble in the pack to the last.

Key Thimble Characteristics

• Smooth interior surface minimizes sample adhesion to the thimble wall, promoting quantitative transfer of extracted analytes to the collection flask.
• Closed-bottom design eliminates the need for secondary containment, allowing direct loading of powdered, granular, and semi-solid sample materials.
• Smooth interior wall surface promotes complete analyte transfer to the collection flask, minimizing sample loss from wall adhesion.
• High-purity alpha cellulose cotton linter construction delivers excellent mechanical strength and low extractable background for demanding analytical extraction workflows.
• Seamless closed-bottom construction securely contains powdered, granular, and semi-solid sample materials without secondary containment requirements.

Reproducible extraction performance across production lots means your laboratory can focus on interpreting data rather than troubleshooting consumable variability. For applications like these, precise dimensional fit within standard Soxhlet apparatus ensures efficient solvent cycling through your samples, maximizing analyte recovery in every extraction run. Choose Whatman products to ensure that your filtration step meets the quality expectations established by one of the most recognized names in laboratory science.
