Glassware laboratory equipments are of different types and categories. They include Adapters, Burettes, Pipettes, Thermometers and many more.
There are many online sites from where one can buy the equipments. I have been buying lab equipments for a very long time for my research purposes. I have been buying things from Science Equip. They have a very good quality and they are very reliable. According to me you can always trust them and buy your laboratory supplies from them.
