Re: Lighting Bunsens
Do you give out a set of gas lighters or one to the teacher and they go around and light them for the students?

Re: Phenolphthalein Agar
Hey,
So I've got this agar from 3-4 weeks ago. It's been stored in the fridge uncovered and has cracked and come away from the edges as you can see.
How do you all store yours for the next time someone wants to do this?
Is it past saving now?
Thanks

Yes DoE here,
Thanks again

Re: Hazardous Chemical Register
I'm currently doing the school stock take now to get a head start on it, and even if something is not hazardous or a DG product I still just keep a copy of it. Just a habit really. It takes twice as long now because of all the extra hand sanitisers and disinfectants in every staff room and store roo...

So for each 4 plates: x4 plain x4 glucose x4 saccharine x4 Acesulfame x4 Sucralose They want the sugars to be made up in the agar as it sterilises so its all distributed evenly when it com...

Re: Automatically Logging Out
Since I joined chemtalk I've always been logged out even when clicking remember me.
I've tried internet explorer, chrome and edge, they all do it even after clearing cookies.
Don't know what the problem is

Re: dynamo
Thanks, yeah we've tried that. Both ways it doesn't work, and I forgot to mention the wheel does spin easily, so not sure what the problem is yet.
thanks for your help though!

Re: dynamo
Hello!
Does anyone have any ideas on how to fix this dynamo?
We've checked the LED's and the bulb, they work, and the connections from the contacts work. So no issue with the wiring from there.
We're thinking it's maybe the magnet or copper in there?
Thanks!

Re: Power Supply (Transformers)
Hi Brains trust!
We have 2 of these transformers and when connected they keep saying overload. We've tried changing the fuse in the back but no luck.
Does anyone have any ideas?
Thanks!
