500ml Pyrex Buchner flask, with 9mm side arm.
A Buchnerflask, 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, 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, which is designed to prevent the sucking back of water from the aspirator into the Buchnerflask.
The side arm on all sizes accepts 9mm bore tubing.
