Re: Venting about ventilation...

I complained about the fume cupboard a number of times, it sounded like something had been dropped from where it exits on the roof, apparently twice the contractors came and didn't find anything, so I recorded the sound that the fume cupboard was making and that got them out again. This time a poor ...

I did a quick search but couldn't find an exact answer to this question.
I need to order Lithium for 2025 but none of the suppliers I normally use stock it, I can buy Potassium and Sodium from them without an issue but considering we are not really meant to use Potassium it appears the ...

Re: Limit on number of Practicals done each week?

Hopefully my bosses don't see this.
I work in a small by Tasmanian standards college (Years 11 and 12 only) and if I worked out my service factor correctly it does not start with a 0, and even if I include 2 subjects that run in the science block that aren't strictly science then it still does not ...

I contacted IEC as LABAX does not seem to exist anymore and they sent me the instructions for their newer model and did not have the instructions for that model

Re: Ordering for Practical Lessons



This is the first year the teachers have booked their pracs online via Risk Assess. When I set it up, I let them know that I would need at least a weeks notice for most pracs. They started out well, but are slipping already! So I've set mine for 5 days ;)

Re: Phenolphthalein Agar

If you are worried place it in either NaOH (if its the clear one) or an acid (if its the pink one) as I believe the pH should be neutral or close to when the colour has changed to the opposite so pink to clear or clear to pink, drain and then throw in bin or just throw straight into bin
