We actually do have a transformer in CCL - just bought one not too long ago, because we were planning to do some messing around with high voltage. It's at the end of one of the lab benches, right next to to the rotovap. Has 110V and 220V outlets, and should be able to do up to 1500W. 

I *think* it's an isolation transformer rather than an autotransformer, but I couldn't actually find any documentation saying so explicitly, so someone should check first! You should be able to check resistance between input and output windings - if it's an autotransformer there will be a direct copper path between input and output; if it's an isolation transformer the two should be disconnected.

We bought this one for CCL (cheaply, but with, like, actual real money!), so please put it back after you use it...

does sudoroom have an isolation transformer?  it's something that plugs into a regular outlet and outputs the same voltage, but it's isolating.

we have a couple of universal AC converter boxes which provide 240VAC when you plug them into 120VAC but they are "autotransformers" and they don't isolate.

I want us to have an isolating transformer so that when people experiment with AC-powered devices, they are much less likely to suffer a lethal shock and die.

note:  some voltage-regulator transformers are isolating, but since they distort the waveform in order to achieve the voltage stabilizing, they are not ideal for our purposes.

thank you,
