Important Technical Parameters of Cellulose Extraction Thimbles

Hawach will introduce cellulose extraction thimble from six technical parameters: material, temperature and forming time, DOP retention, size selection, porosity, and fitting accuracy.
●Material
The consistency of component content of extraction thimbles made of different materials and those made of the same material has a great influence on the determination accuracy of various detection and analysis.
Cellulose extraction thimbles consist of high-grade alpha cellulose/seamless noble cellulose and linters of cotton without any binding elements(60% high-clean poplar fiber +40% refined cotton fiber).
●Temperature and forming time
The relevant temperature parameters and forming the time of the cellulose extraction thimbles can reflect the tolerable working temperature to a certain extent and the requirements of special working conditions. Relevant parameters are as follows:
The heating temperature: 75℃;
The forming temperature: 10℃;
The forming time: 1Hour;
The maximum temperature is 100℃;
●DOP Retention
The DOP Retention is a reflex of retention ability. The DOP Retention(% @0.3) of cellulose extraction thimbles is 99.8% .
● Size selection
As shown in the figure below, ID represents the inner diameter of the filter cartridge, H represents the height of the cellulose extraction thimbles, and wall thickness reaches the thickness of single-sided thimbles.

●Porosity: Consistent high porosity ensures fast flow through.
●Fitting accuracy: High fitting accuracy for all available extraction systems.
