Septa seal the two conical flasks. A cannula is used to transfer THF from the flask on the right to the flask on the left.. Cannula transfer or cannulation is a set of air-free techniques used with a Schlenk line, in transferring liquid or solution samples between reaction vessels via cannulae, avoiding atmospheric contamination.
the use of syringes and rubber septa to transfer liquids and solutions; [6] cannula transfer, where liquids or solutions of air-sensitive reagents are transferred between different vessels stoppered with septa using a long thin tube known as a cannula. Liquid flow is supported by vacuum or inert-gas pressure.
This is a data module for Module:Adjacent stations.It supports services operated by the Southeastern Pennsylvania Transportation Authority (SEPTA), including SEPTA Regional Rail, the Norristown High Speed Line, the Broad Street Line, the SEPTA subway–surface trolley lines, SEPTA Route 15, SEPTA Routes 101 and 102, and the Market–Frankford Line.
A Schlenk flask, or Schlenk tube, is a reaction vessel typically used in air-sensitive chemistry, invented by Wilhelm Schlenk.It has a side arm fitted with a PTFE or ground glass stopcock, which allows the vessel to be evacuated or filled with gases (usually inert gases like nitrogen or argon).
Heat transfer by thermal radiation may be minimized by silvering flask surfaces facing the gap but can become problematic if the flask's contents or surroundings are very hot; hence vacuum flasks usually hold contents below the boiling point of water. Most heat transfer occurs through the neck and opening of the flask, where there is no vacuum.

It is often used in combination with a Büchner flask, Büchner ring and sinter seals. A vacuum tight seal and stability of the Büchner flask and filter are essential during the filtration process. A Büchner ring can be used with Büchner funnels, flasks, glass crucibles and Gooch crucibles. The wide flange and large surface contact ensures ...
The line passed into Conrail in 1976 and SEPTA in 1983, with passenger service to the Philadelphia International Airport beginning on April 28, 1985. [ 5 ] Infill stations were planned from the beginning of service, two of which were on the Airport Line proper: one at 70th Street, the other one at 84th Street.
