Glass Fiber Extraction Thimbles

Material: high purity borosilicate glass fibers
Completely free of binders or additives
Used: 1. temperatures up to 500°C (932°F)
2. solvents incompatible with cellulose thimbles
3. air and waste gas analysis for collecting solid particles (dust)


Description of Glass Fiber Extraction Thimbles

Hawach glass fiber extraction thimbles are made of high purity borosilicate glass fibers. It is often used at temperatures above 120 degrees Celsius, and the compatibility of cellulose cartridges cannot meet the requirements. It is widely used in air and waste gas analysis for collecting solid particles.
