Product Overview

Whatman 603G glass thimbles are precision-engineered for demanding laboratory filtration tasks, offering exceptional chemical resistance and thermal stability. Constructed from high-purity borosilicate glass, these thimbles ensure compatibility with a wide range of solvents and reagents, making them indispensable for Soxhlet extraction, gravity filtration, and sample preparation. The uniform porosity and smooth surface minimize particle retention, ensuring efficient flow rates and consistent results. Their robust design withstands repeated autoclaving and high-temperature applications without compromising structural integrity. The transparent glass allows for easy visual monitoring of filtration progress, while the standardized dimensions ensure seamless integration with standard lab apparatus. Whether used in academic research or industrial quality control, these thimbles deliver reliable performance for critical filtration processes. The inert nature of borosilicate glass prevents leaching or contamination, maintaining sample purity throughout experiments. Available in multiple sizes to accommodate varying sample volumes, these thimbles provide versatility for diverse laboratory applications. Their durability reduces replacement frequency, offering long-term cost efficiency for high-throughput laboratories.
