what is a flask for what is a flask for
This flask is used to collect the filtrate from the filter.
A Buchner flask is a flat-bottomed flask used in filtration setups with a sidearm to attach a vacuum source. A filter flask has a sidearm with an angled neck to connect to a vacuum pump for filtration. A side-arm flask typically has a single sidearm used for connecting to other glassware or apparatus.

This is a conical flask from glass or plastic, frequently used in all chemical laboratories; the Erlenmeyer flask may contain reagents, collect filtrates, labware for a chemical reaction, it is used for titration, etc. It is not a filter.
A Buchner funnel and a vacuum flask are commonly used in laboratories to support filter paper during filtration. The Buchner funnel is specifically designed to hold filter paper and can be connected to a vacuum flask to speed up the filtration process by applying suction.

You should remove the rubber tubing from the filter flask after the filtration process is complete and there is no more liquid passing through the tubing.
From Wikipedia.com (see Link to the left):A Büchner flask, also known as a vacuum flask, filter flask, side-arm flask or Kitasato flask, is a thick-walled erlenmeyer flask with a short glass tube and hose barb protruding about an inch from its neck. The short tube and hose barb effectively acts as an adapter over which the end of a thick-walled flexible hose (tubing) can be fitted to form a connection to the flask. The other end of the hose can be connected to source of vacuum such as an aspirator vacuum pump or house vacuum. Preferably this is done through a trap (see below), which is designed to prevent the suckback of water from the aspirator into the Büchner flask.See the Web Links and Related Questions to the left for more information.
A filter funnel is a funnel shaped filter that is used to separate solids from liquids. By passing the mixture of solid and liquid parts through a filter, which is either a piece of filter paper or a glass frit, the solids remain in the filter funnel and the liquid is passed into a collection flask below. A Buchner funnel is typical kind of filter funnel.See the Web Links to the left for more information about filter funnels.A funnel is a pipe with a wide, often conical mouth and a narrow stem. It is used to channel liquid or fine-grained substances into containers with a small opening. Without a funnel, much spillage would occur.
1.Filter flask
Common equipment used in filtration include filter paper, filter funnel, filter flask, vacuum pump, Büchner funnel, filter holder, filter membrane, filter aid (such as diatomaceous earth or activated charcoal), and filter press. These tools are utilized to separate solids from liquids in a variety of applications across industries such as chemistry, biology, and environmental science.
