Let’s learn about the storage methods of glass instruments
[Storage of glassware]
In the storage room, glass instruments should be stored in separate categories for easy access. Frequently used glass instruments should be placed in the laboratory cabinet. The tall and large glass instruments should be placed in it. The following are some methods for keeping the instruments.

3. After the cuvette is cleaned after use, put filter paper in a porcelain or plastic dish, put it upside down to dry, and put it into a cuvette box or a clean container.
4. Apparatus with ground stopper Before washing the volumetric flask or colorimetric tube, use a rubber band or a small string to fasten the stopper and the nozzle, so as not to break the stopper or confuse each other. For grinding instruments that need to be stored for a long time, a piece of paper should be placed between the plugs to avoid sticking for a long time. The burette that has not been used for a long time should be put on paper after removing the petroleum jelly, and the piston should be secured with a rubber band for storage.
5. Complete sets of instruments such as Soxhlet extractor, gas analyzer, etc. should be cleaned immediately after use, and stored in a special carton.
In short, we must be in the spirit of being responsible for the work, clean all the glass instruments used after they are used up, keep them as required, and develop good working habits. Do not put oil, acid, corrosive substances in the instruments (including Concentrated lye) or toxic drugs to avoid future troubles.[ Burette 25ml,Burette 50ml,Burette 100ml,Laboratory Burette ] [ glass measuring pipette,measuring tube pipette,10ml glass measuring pipette ]
