Objective
To prepare a Schlenk line,
Materials
- Schlenk line
- Stopcock
- 2 elastic bands: one is to hold the stopcock to the schlenk line together and the other one is to hold the head of the schlenk flask to its body.
- Vaseline
Method
- Put a small portion of vaseline on the frosty part of the stopcock.
- Rotate the stopcock in your hands so that the vaseline is well spread.
- Grab the elastic band which will be useful to keep the stopcock in its place. To do this, we will turn the stopcock so that it is perpendicular to the Schlenk tube. Then, we will put the elastic band on the lower part of the Schlenk tube, on top of the lip part and pull it far away from the stopcock. Then, pass the elastic band straight over the stopcock, you then twist the elastic band (the cross needs to stay underneath the arms of the Schlenk tube) and pass it over again , twist again (again, the cross needs to stay underneath the arms of the Schlenk line), pass it over again, and finally, put the elastic band in the initial position.
Final stopcock:
- Put a bit of vaseline on the frosty part of the body of the Schlenk tube to keep the head of the Schlenk tube together with the lower part.
- Attach the head of the Schlenk tube to its body.
- Turn twice the elastic band on our fingers, hook it up to one of the two wire supports of the Schlenk tube, pass the elastic band underneath the body of the Schlenk line and hook it up to the other wire support.
Final schlenk tube:
