#1 Science Forum For Lab Technicians

Hi team, Maybe I am showing my age here, but does anyone have any good sources for electronic project kits, I mean since Dick Smith Electronics closed I am struggling to help the teachers out, who still wish for students to solder electronics together. Jaycar have some but not a great selection. I k...

Hi all, 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 react...

Hi everyone, I know this is an oldish thread but thank you. As I have moved schools from where I was provided with a bar fridge to a school which has a full size fridge and freezer and also a deep freezer also full size and not the tucker box style and am about to get in 12 plucks. Did kidneys today...

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 s...

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
Thanks

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 ;) WOW I wish Wowsers at least a week, we have...

Hi all, Firstly I searched the forums for some information and there seem to be a few questions similar but not what I was after. So I have 2 types (illustrated below) of Geiger Counters/Timer Counter Scaler Frequency apparatus and am after the instructions for them or if anyone has knowledge of how...

Anyone have any good places to purchase/obtain biology posters and models?


Thanks

Hi all,

Does anyone do much 3D printing? If so do you have some favourite bits that you have printed and found useful in your work?
Thanks

I would prefer making Whisky

We are making wine in one of our classes starting tomorrow, however we cannot call it wine making so its become a fermentation experiment but using grapes and wine yeast and products I have purchased from the home brew shop

Love it, I just made one using hay/straw that had been left on the compost stack in our orchard

Funding has been received from the Federal Government to enable Science Assist to continue in 2022, however you still need to register and pay, although the fee has been reduced for Australian Schools to $100.00 excluding GST. I just read about this in the March edition of Teaching Science, the Aust...

I know places like Supercheap Auto etc sell 12v/5w for stop or tail lights which have two base contacts and offset pins. They also sell festoon bulbs (interior light bulbs) in that rating and also wedge globes in that rating. They all may be different to what you need as I not sure what you are usin...

Hi all, Any advice would be appreciated: I have an allergy to latex so don't use latex gloves and usually use nitrile gloves, however now it seems I am developing an allergy to nitrile gloves, can anyone suggest a suitable replacement type of disposable glove or what do you do if this is the same fo...

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

Hi all, A Teacher has provided me with an experiment that uses Mercury (II) Chloride to remove the Aluminium Oxide layer on a piece of polished Aluminium foil, now I looked at Riskassess and it says Mercury(II) Chloride <0.004 M (<0.1% wt/wt) is a Teacher only chemical. They now wish me to find an a...

Thanks Anna Z for that awesome suggestion as well

Hi all,

Hope you had a restful break and are hopefully coming into 2022 recharged. I know I am and I am looking forward to having a good year
Cheers

Andrew
