drying tube... odd configuration
Hey, I've only worked with drying tubes once before and they were simple and straight like this:

Now they seem to be popularly like this:

Why? I'm assuming I attach them to the same spot - atop the condensor in a refluxing reaction, but now I have to plug both holes with cotton.

I have one that's a full 180 degree turn, with only one ground glass joint.
I think it varies from drying tube to drying tube - all work just as well.

Yes, those are common too. Personally, I use a Kjeldahl bulb packed with anhydrous CaCl2 and plugged with ordinary cotton wool for a drying
tube, which seems to work adequately.

In case the cotton plug on the bottom fails partly hydrated CaCl2 will fall into your apparatus. This might be problematic in some cases. Also really
high apparatuses are easier to tip over and break.
