The Schlenk Line is used for the handling of air or water sensitive chemicals. It consists of a gas manifold (for delivering either argon or nitrogen), a vacuum manifold (for evacuating glassware), and a vacuum pump (attached to the vacuum manifold).

What is a Schlenk line used for?

The Schlenk Line is used for the handling of air or water sensitive chemicals. It consists of a gas manifold (for delivering either argon or nitrogen), a vacuum manifold (for evacuating glassware), and a vacuum pump (attached to the vacuum manifold).

What is Schlenk technology?

A Schlenk line is an essential piece of equipment used for the manipulation of air and moisture sensitive compounds. They consist of a vacuum manifold which is connected to a vacuum pump, and an inert gas manifold which is connected to a source of purified and dry inert gas (typically argon or nitrogen).

How do you use a Schlenk flask?

Using a Schlenk flask

  1. Connect (using rubber tubing) the sidearm to a nitrogen manifold and bubbler.
  2. Open the sidearm valve and turn up the nitrogen flow (watch the bubbler).
  3. Remove the stopper from the flask.
  4. Place the addition funnel on the flask and allow the apparatus to purge completely with nitrogen.

How do you transfer a cannula?

1) Insert the cannula into the receiving flask. 2) Place a bleed needle of the same gauge or smaller than the cannula into the receiving flask. Close any other inlets to the flask. 3) Submerge the needle into the solution of the starting flask, and the cannula transfer should start within seconds.

When was Schlenk line invented?

1920s
A Schlenk line is a dual manifold used in the safe handling of air- and moisture-sensitive reagents. The apparatus was invented in the 1920s by Wilhelm Schlenk.

What is the pump fill method?

It involves sonication of the solvent while under light vacuum (i.e., house vacuum) and the refilling of the atmosphere with inert gas. The solvent is sonicated for up to a minute each time and the process is repeated 5–10 times. This is the most effective method of degassing a solvent.

How do you evacuate a flask?

Evacuating a Schlenk flask A common method of exchanging the atmosphere of the flask is to flush the flask out with an inert gas. The gas can be introduced through the sidearm of the flask, or via a wide bore needle (attached to a gas line).

What is the difference between a catheter and a cannula?

What is the difference between Catheter and Cannula? Cannula is a short flexible tube which is introduced into a blood vessel, while Catheter is defined as a tube which is substantially longer than Intra Vascular Cannula for peripheral access to body.

Is a cannula an IV?

Definition of terms. Peripheral IV devices: are cannula/catheter inserted into a small peripheral vein for therapeutic purposes such as administration of medications, fluids and/or blood products.
