Glass cleaning techniques used in experiments

Central laboratories or chemical storage rooms in general should be located in areas where sunlight does not reach directly. And the weather is not too hot With a door completely Corridor and chemical placement Must be appropriate Each type of chemical storage rack must be of good quality. Can prevent chemical flow Must be installed / assembled intensively and placed on the wall Has characteristics and properties that are resistant to burning Resistant to reaction and corrosion resistance According to the type of chemicals stored Glassware should be separated from chemicals. Because some chemicals can destroy the flesh of the glass Causing damage to the performance of the scientific glass As well as having to keep the cleanliness of the place regularly.

Glassware used in the experiment must always be thoroughly washed. Otherwise, the result of the experiment will be wrong or deviated from the truth. The general principles of glass washing used in the experiment are as follows:

1. Clean the glass immediately after use. To make glassware Dry before being used for the next time If dirty glassware needs to be washed before the experiment Lost Time Because it cannot be washed immediately

2. Glass cleaning Must be done with caution especially the machine Long-stemmed glass such as volumetric bottles, pipette, burette, etc.

3. As usual, washing the glass will often use soap or detergent or cleaning solution, so the soap must be washed. Detergent or solution to clean out completely, if there is residual May interfere with chemical reactions

4. Washing the glass used in the laboratory generally will be washed with a brush using soap, detergent or cleaning solution, as the case may be, then washed with clean water. And in the final stage, must be washed with distilled water again 1-2 times. If the glass is clean, it will notice that the water on the glass surface is uniformly uniform. But if the glassware is not clean Will notice a drop of water coming to the side of the glass

5. Using the converter to wash the glass must be very careful. Because the metal brush rod may cause Broken glass There are many types of glass washers, many sizes must be used to suit the characteristics of the glass.

Warning
Washing glassware using a brush Do not rub too hard Since the brush rod is metal when impacting the glass, it can cause breakage and danger.
