Product Overview

Whatman silica extraction thimbles are engineered for superior performance in solvent and Soxhlet extraction applications. Made from high-purity silica fibers, these thimbles offer exceptional thermal stability, resisting temperatures up to 1000 C without deformation or degradation. Their robust construction ensures minimal particle shedding, maintaining sample integrity during rigorous extraction processes. The uniform porosity and high retention capacity allow for efficient solvent flow while preventing fine particulate matter from passing through. These thimbles are chemically inert, making them compatible with a wide range of organic and inorganic solvents, including acids and alkalis. The smooth inner surface minimizes sample loss, while the rigid structure prevents collapse under vacuum or pressure. Each thimble undergoes stringent quality control to ensure consistency in dimensions and performance. Available in standard sizes, they are designed to fit most laboratory extraction apparatuses seamlessly. The silica composition provides excellent resistance to thermal shock, making them reusable after proper cleaning. These thimbles are an essential tool for laboratories requiring reliable, high-efficiency extraction solutions.

FAQs
