swan neck tubes
Hi all,
has anyone purchased swan neck tubes recently?
If so, where from, please?
I'm being a slacker and don't really want to have to make them!

Re: Melting Phenolphthalein Agar
Good to know. What strength Phenolphthalein did you use and how much? I find it's so hard to get the right colour so it doesn't fade. usually make it too pink. I actually can't tell you the strength, the bottle I have here was made up prior to me being here! It's almost gone now......time to make u...

Potassium Iodide
Hi all, I have a question about the colour of Potassium Iodide. I have a small amount in a bottle, made up some time ago, that is a strong yellow colour. I needed to make some up today, it is clear. The older solution says saturated, the one I made today is 2M. What colour should it be ??? TIA Helen.

Re: Removing rubber stopper from small conical flask
A while ago I had a rock stuck in a perfectly good measuring cylinder ( by a student )
I did try a few remedies, one was soaking it in an acid to try to eat away the rock..............but alas, I had to throw it out!
