Background technology
It is the common device of laboratory that glass drying oven soaks sour cylinder, in experimentation, glass drying oven will be avoided contaminated or
Person's previous run material is remained on glass drying oven, therefore needs to soak glass drying oven using acid solution before next experiment is carried out
Bubble.Required according to different experiments, the species of the acid solution for being used is also different, but no matter which kind of acid solution is used, be all tool
There are high concentration, severe corrosive, strong oxidizing property and strong volatility, all there is potential danger to operator.Using traditional
When sour cylinder soaks glass drying oven, operator needs directly with handss, glass drying oven to be put in sour cylinder one by one, and great majority
In the case of acid solution can not be advanced into certainly glass drying oven, need external force by means of handss by glass drying oven by making acid solution stream in acid solution
Enter glass drying oven, therefore it is difficult to avoid the directly contact of acid solution and skin.When glass drying oven is soaked using classical acid cylinder,
Glass drying oven is typically disorderly stored in sour cylinder in a jumble, and it is crushed that this easilys lead to some glass drying ovens, while taking
Go out immersion glass drying oven when, the glass drying oven residues of these crushing may scratch the handss of operator.Using tradition
When sour cylinder soaks glass drying oven, the label paper on the glass drying oven in acid solution that comes off can directly sink to sour cylinder bottom portion,
All it is difficult cleaned before changing acid solution, the label paper extended residual in acid solution that drops can affect the immersion of acid solution in acid solution
