ANALYSIS OF THE USE OF DESICCATOR INSTRUMENTS: Literature Review

Abstract

The laboratory is an indispensable tool in science learning. In the laboratory there is a lot of equipment that supports practical work carried out by students. So that the equipment used can be used for a long period of time, it needs to be maintained regularly. Generally laboratory equipment consists of metal, wood and glass. Maintenance of the tool is carried out by storing the tool in a dry place and not exposed to sunlight. Various kinds of laboratory equipment such as glassware: test tubes, Erlenmeyer, measuring cups, etc. Another frequently used equipment is a desiccator.  A desiccator is a tool commonly used in laboratories that functions as a tool for cooling samples. The goal is to analyze desiccators, identify desiccators, principles, various types of desiccators, know how to use them and maintain them. Method : This research is descriptive research using a literature review method with reference sources from Google School, Sinta, national and international journals. Result : A desiccator is a tool used as a tool to cool samples. This tool is closely related to the field of chemical engineering. The various types of desiccators are standard desiccators, gas cleaning desiccators, automatic desiccators, vacuum desiccators. The way the desiccator works is to open the lid of the desiccator by moving the lid to the side, place silica gel underneath, place a filter made of porcelain, place the media on top of the filter, before closing, apply a little Vaseline to the lips of the cover. Lastly, set the tap and no air should enter the desiccator. Conclusion : A desiccator is a tool used as a tool to cool samples. It is important to always calibrate the equipment to maintain the quality of the desiccator so that it continues to function properly
