Glass or plastic bottles of different types.
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.
Actually there are 6 types under the heading gymnastics. These are: Artistic, Rhythmic, Acrobatic, Aerobic, Tumbling and Trampolining. Each different types arose due to different areas being incorporated within the FIG. Artistic uses the apparatus, Rhythmic uses the 5 portable apparatus, Acrobatic uses the floor as a pair or team without apparatus, Aerobic is like doing vigourous exercise on the floor, Tumbling uses a 25 metre springy mat and Trampolining obviously uses a trampoline.
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.
check out this link http://www.laboratoryequipmentworld.com/chemistry-lab-equipment.html it talks about a few types of apparatus and their uses.
Examples: distillation apparatus, filtration apparatus, installations for synthesis in organic chemistry, installation for separation by solvent extraction, laboratory demineralization apparatus etc.
A beaker..?
Once in space, an astronaut uses a special breathing apparatus. Corruption had spread throughout the city's political apparatus.
