I just put through a prac as a test and had no problems here. Haven't had that issue before.
I hope it gets fixed for you, such a valuable resource

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

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!

Hello!
Does anyone have any ideas on how to fix this dynamo?

Does anyone have any ideas?

DoE school. Yes that makes sense, thank you. I'm only here 2 days a week to help the full time labbie. And I've been told everyone is too busy to get it done and I'm here to go collect the details. Before I was here I the labbie told me she would email them and ask for their stocktake but they'd be ...

Hi all, Just wondering if any of you have been asked to do a chemical stocktake for the entire school? Or do you just record science? I've been trying to find some information on this but can't find anything other than forums but I have read somewhere that you don't need to record the chemical if it...

May I have a copy please too?

Wonderful, thanks Labbie

Hi
this might be a dumb question, but I followed the instructions in 'the laboratory', so when the solution settles am I meant to decant that liquid into a bottle? or just do it now when its a milky colour?

thanks!

I didn't get to it yesterday so it sat in the fume cupboard overnight thankfully!
Thanks Merilyn

Amazing, Thank you

Hi sorry to post, I tried looking for a similar post and I couldn't find one,

A teacher has made a carbon snake with concentrated sulphuric acid and sugar.

How do I dispose of this??

Thank you

Heya.
If using the dropper trays (or any trays), does the agar come out easily enough or does it stick to the edges?

Thanks

Hey,
Just wondering. I've had the eggs in from the beginning of the day, how long does the process usually take to complete?
And is it bad if I leave them in the fridge still in the vinegar over the weekend to complete? Or will this just further break them down?
Thanks!
