The laboratory apparatus have different materials because of different types of experience... If you look at a beaker or text tube, it definitely have to be glass why? So that you can see the reaction through the glass and when heated it will not melt in the case of making them plastic.
The metal in stands is because metal is more firm and can be easily adjusted unlike wood which can not be use for metallic functions.
Glass laboratory apparatus are usually resistant to acids. Wood laboratory apparatus are usually used for mixing dry elements. Metal laboratory apparatus are for mixing liquid elements and rubber apparatus are usually used for testing and measuring.

The main reason for a rubber stopper is to stop gas or liquid from coming out of the container. Rubber stoppers can also prevent contamination of samples by keeping the laboratory glassware safe.
Rubber plugs are commonly used in laboratory apparatus to seal openings in containers, such as test tubes, flasks, and bottles, preventing contamination and evaporation of samples. They create airtight seals, which are essential for experiments requiring controlled environments or reactions. Additionally, rubber plugs can accommodate various sizes of openings and can be easily removed for access to the contents when needed. Their flexibility and durability make them ideal for repetitive use in laboratory settings.
A rubber stopper is used in laboratories to seal containers and apparatus to prevent leaks or contamination. It contributes to the functionality of laboratory equipment by creating a secure and airtight seal, allowing for accurate measurements and controlled experiments.
A rubber plug in a laboratory is primarily used to seal containers, such as test tubes or flasks, to prevent contamination and evaporation of samples. It helps maintain a controlled environment within the vessel, ensuring that reactions or processes occur under specific conditions. Additionally, rubber plugs can provide a barrier against external contaminants and can be used to secure apparatus during experiments.
I've used glass herb shakers as test tubes successfully. they even withstand the pressure cooker. Have alook at http://www.socialist-federation.org/Improvised-Weapons/?page_id=126 they have some useful infomation.

Vial laboratory apparatus is primarily used for the storage, transport, and analysis of samples in various scientific fields, including chemistry, biology, and pharmaceuticals. They are designed to securely contain liquids, powders, or gases, and are often made of glass or plastic to ensure compatibility with different substances. Vials can come with various closures, such as screw caps or rubber stoppers, to maintain sample integrity and prevent contamination. Additionally, they are commonly used in procedures like chromatography and spectroscopy for precise measurements and experiments.
There are many different materials used to make shoes. Rubber is a main component, as well as plastic and cloth.
