Cellulose Soxhlet Extraction Thimble, Double 2 mm Wall, 22x80mm (25 pcs) SKU: 2810-228

Cellulose Extraction Thimble - 2810-228

Pharmaceutical raw material testing and food quality analysis protocols specify extraction thimbles that provide documented purity and consistent mechanical performance across every unit. Moreover, Whatman manufactures this device with the same process controls applied across its filtration portfolio, ensuring rated performance is verified at the production lot level. High-purity cellulose construction balances the permeability needed for efficient solvent circulation with the mechanical integrity to retain fine particulate samples. Accordingly, uniform construction quality delivers the reproducible performance that standardized extraction methods require for defensible analytical reporting.

Key Thimble Characteristics

• Smooth interior surface minimizes sample adhesion to the thimble wall, promoting quantitative transfer of extracted analytes to the collection flask.
• Mechanical strength sufficient to maintain structural integrity when saturated with solvent and loaded with sample, even during extended multi-hour extraction cycles.
• Uniform wall construction maintains consistent solvent flow distribution across the thimble surface, preventing channeling that could reduce extraction efficiency.
• Natural cellulose fiber composition enables rapid solvent wetting without pre-conditioning, reducing setup time for routine extraction procedures.
• Alpha cellulose cotton linter fiber composition provides high purity with minimal extractable residues for accurate gravimetric and chromatographic analysis.

Consistent thimble quality across every pack gives your laboratory the confidence to report extraction results without questioning the consumable. For this purpose, consistent lot-to-lot manufacturing quality ensures your extraction workflows produce reproducible data without introducing consumable-driven variability between sample batches. Integrate Whatman filtration into your protocols to benefit from the brand recognition, lot documentation, and performance history that analytical laboratories trust worldwide.
