Material and Application of Extraction Thimbles
We recommend materials and applications of two kinds of extraction thimbles in Hawach.
The material of extraction thimbles
Due to different materials of extraction thimbles, two types of extraction thimbles are sold in the Chinese market. Cellulose extraction thimbles: high-grade alpha cellulose/seamless noble cellulose and linter of cotton without any binding elements(60% high-clean poplar fiber +40% refined cotton fiber).
Glass fiber extraction thimbles: the advanced special glass wool
Application differences and emphases
Cellulose extraction thimbles are particularly suitable for the extraction of indoor dust /toxic organics (phthalic acid) / natural substances, lacquer and binder analysis in paint colors, dust and tar determination in gases, and other similar simple Soxhlet extraction of organic components.
Glass fiber extraction thimbles are always used in specific Soxhlet extraction, such as temperature higher than 120℃, strong acid cellulose filter cartridge is not suitable for. Glass fiber extraction thimbles are also applicable to the detection of stationary pollution sources: flue gas, smoke, and dust, such as cadmium, nickel, tin, and fluorine, etc.
In addition, it is a highly efficient filter for dust, acid mist, beryllium, and other harmful substances, environmental /air exhaust detection, such as arsenic, dioxin, lead, asphalt smoke, sulfuric acid fog.
