Extraction Thimble is An Indispensable Part For Soxhlet Extractor
The Soxhlet extractor has a reasonable design, stable performance, high accuracy, labor-saving and time-saving operation, which is ideal extraction in food, oil, feed, soil, and other industries. There are three main components, heating extraction, solvent recovery, and cooling.
Main features of Soxhlet extractor:
1. The heating temperature can be adjusted according to the boiling point of the reagent and the environmental temperature during operation;
2. The sample of the fat analyzer is soaked and extracted repeatedly in the extraction process to achieve the purpose of rapid extraction;
3. The solvent can be automatically recovered, which greatly facilitates the use of users and saves a lot of time;
4. The extraction time is adjustable, and it will alarm when it is reached.
The important part for soxhlet extractor–extraction thimble
The extraction thimble is mainly used to place the substance to be extracted in the glass container below, and then the solution is repeatedly soaked in the substance to extract the required components from the substance.
Grind the solid matter before extraction to increase the solid-liquid contact area. Then, the solid matter is placed in the extraction thimble of the extractor. The lower end of the extractor is connected to a round bottom flask containing the leaching solvent, and a reflux condenser is connected to the upper end of the extractor. The round-bottom flask is heated to make the solvent boil, and the vapor rises through the connecting pipe, enters the condenser, and drops into the extractor after being condensed. The solvent and the solid contact for extraction.
When the solvent level in the extractor reaches the highest point of the siphon, the solvent containing the extract is siphoned back to the flask, thereby extracting a part of the substance. Then the leaching solvent in the round-bottom flask continues to evaporate, condense, leaching, and reflux, and so on so that the solid matter is continuously extracted by the pure leaching solvent, and the extracted matter is enriched in the flask.
Tips for Operation of Extraction Thimble
Extraction thimble is to use the solvent reflux and siphon principle to make solid matter continuously extracted by pure solvent, which not only saves solvent but also has high extraction efficiency.
The solid material is ground before extraction to increase the area of solid-liquid contact. Then, the solid material is placed in the filter paper bag and placed in the extractor. The lower end of the extractor is connected with the round bottom flask containing the leaching solvent, and the reflux condensing tube is connected above.
Heat the round bottom flask, make the solvent boil, the vapor rises through the connecting tube, enters the condensing tube, drops into the extractor after condensation, the solvent and solid contact for extraction, when the solvent level in the extractor reaches the highest level of the siphon, the solvent containing the extract siphon siphons back to the flask and extracts some substances.
Then the leaching solvent in the round bottom flask continues to evaporate, condense, leach, and reflux, so that the solid matter is continuously extracted by the pure leaching solvent, and the extracted substance is enriched in the flask.
Liquid-solid extraction is to achieve the purpose of extraction and separation by using a solvent to the solubility of the required components in the solid mixture and the solubility of impurities.
HAWACH provides two kinds of extraction thimbles(cellulose and glass fiber) to meet different soxhlet extractor demands. For example, the cellulose extraction thimbles are for general Soxhlet extraction, indoor dust, indoor toxic organics (dicarboxylic acid), etc. and the glass fiber extraction thimbles are suitable for the Soxhlet extraction when the temperature is higher than 120°C, strong acid and other cellulose thimbles cannot be tried.
