Mar 20, 2022
The tetrafluoro beaker is an instrument often used in the laboratory. It has many advantages, such as high and low temperature resistance, corrosion resistance, etc. Its working temperature can reach 250 degrees. It has good performance. When you use it, you must know the correct use method and precautions of the instrument. Let's introduce the precautions for using the tetrafluoro beaker.
1. When using a tetrafluoro beaker for heating, an asbestos mesh should be placed under it, and it cannot be heated directly on the fire. This is mainly because the bottom surface of the beaker is relatively large. If it burns to the local area, it will burst due to the uneven heating of the whole, so everyone must avoid this situation.
2. When using the beaker to heat the liquid, do not let it have water on the outer wall, and the amount of the heated liquid should not be more than one-third of the volume of the beaker, otherwise it may overflow after the liquid boils, so it is possible Accidents such as burns occur, so the outer wall of the biscuits must be wiped dry.
3. The beaker cannot hold chemicals for a long time, because it may allow dust to enter or cause the moisture in the liquid to evaporate; when heating corrosive items, use a watch glass to cover the mouth of the beaker to avoid liquid Splashing; when dissolving or diluting, use a glass rod to stir, and be careful not to let the glass rod touch the wall or bottom of the cup.
The above has introduced the precautions for the use of tetrafluoro beakers. When you have operations, you can first understand these contents, especially some details, so that many problems can be avoided; Need to do a good job of cleaning and maintenance of the beaker.
