A tip about apparatus diagrams
You must take care when drawing apparatus with ground-glass joints.
You should not leave such a too large a gap between the inner and outer parts of the joints. Your diagram, or the labelling, should make it clear that no vapour can escape through the joint.
Note that some of the joints drawn in the Nuffield Student's book are open to criticism in this respect.

I believe you can simply draw the apparatus without joints and then add little triangles to show this. It's much easier . . .
