there are several. a bell jar is used to demonstrate how removing air from around a bell prevents us from being able to hear its sound. the other kind that i can think of is a beaker, which is used to mix ingredients. it has measuring markings and a pouring lip, both of which are very useful when doing chemistry. it's made of glass because glass doesn't react to anything except extreme heat.
A container used for collecting gas from experiments. It looks like a tube with a broad base and a broad opening. And i dont know how to use it! it's up to you to discover.. ^_^
Tinatanong ko nga rin kung anong sagot eh! Haynaku! Ang chemistry talaga. :(
It can be used in holding all sort of small or normal
objects
It supports the test tube above it. Maria
The hydrogen in such a reaction can effectively be collected using an apparatus called the gas jar. THis can be done by fitting the reaction flask with cork and a delivery tube running from the reaction flask to the gas jar. As the reaction proceed, the hydrogen evolved will be collected in the gas jar.
Glass lids are slid under the gas jar when gases are being collecting. This is so the water vapor is collected.
It expands to fill the jar and takes the shape of it.
the jar that holds the gas and condomes

A beehive shelf is a piece of laboratory equipment, usually of pottery, used to support a receiving jar or tube while a gas is being collected over water with a pneumatic trough.

senior chemistry textbook? im on that question!
If the gas jar is standing with its opening to the top, then the escaping gas is Hydrogen. If the gas jar is being held upside down ( opening to the bottom), then the escaping gas is carbon dioxide.
Glass lids are slid under the gas jar when gases are being collecting. This is so the water vapor is collected.
Ammonia is collected in inverted gas jar because it is lighter than air.
It expands to fill the jar and takes the shape of it.
A gas jar is used in microbiology. A flame is lit in the airtight jar which starts using up the oxygen in the jar and producing carbon dioxide. This creates an environment that is lower in oxygen than the normal atmosphere and creates a perfect environment for microaerophilic microbes which need a low concentration of oxygen in order to grow. It can also make fire...

There are several uses for a staining jar. In microscopy, it is used for staining tissues and cells for slides. After being stained with dyes or stains, the specimens can also be placed in the jar to look for certain aspects.
Carbon dioxide gas jar is a jar used to grow culture media. It contains carbon dioxide taken from candle flames burn inside the jar. Bacteria and other microorganisms are grown in this jar for further observations.
