It is a very minute but essential part of laboratory apparatus that we use to measure the liquids accurately in science labs at school and colleges. It is usually secured with a burette clamp (which fixes it well that way we can start working on the chemical stuff) A stopcock has a hole in the middle, which liquids to pass through it. We open the stopcock (turning it up), and liquid can come out through bottom. The opposite is true when we close it, where the liquid shuts off instantly. This is very handy, as will allow us to measure the perfect amount of liquid for our experiments without any spillage.

Types of burette stopcocks available are many but have their own pros and cons dosent they. Take the example of glass stopcocks being extremely robust and can have a long lifespan too if they are maintained properly. One downside is that they can be a lot more brittle than plastic stopcocks so dropping or chucking one on the workbench may result in it breaking. In contrast, plastic stopcocks are usually more economical and lighter in weight. However, they are not as robust in comparison to glass stopcocks and therefore will be less durable.

Advantages and disadvantages of different types of burette stopcocks

On top of that, there are stopcocks which have a thin layer of DuPont Teflon on them too. They are able to withstand a more extensive list of chemicals that either the plastic or glass stopcocks, which allows them to be used with experiments utilizing stronger and/or corrosive substances. But, then they might be slightly difficult to manage when in use. At the end of the day, what stopcock provides the optimal solution for your lab will depend on individual experiments and how much money you have to spend on other equipment.
