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 the analysis of air and waste gas to collect solid particles.

Advantage of Glass Fiber Extraction Thimbles

High temperature resistance and efficiency.
Cartridges are made in cleanroom.
Integrity test available.
Wall thickness consistent, ensures precise extraction test results.
All cartridge sizes are here for you to choose from.
Mechanical strength and retention ability are as expected.
Pores are consistent and widely distributed, which ensure fast flow through.
Can be used with all extraction systems available.

Features of Glass Fiber Extraction Thimbles

Sizes vary for different needs.
