Re: Do you use a diary?

Nothing like a Page a Day Diary - a summary of all the pracs (from RiskAssess) in one place, we can scribble room/qty changes, it's easier to see when there are duplicate pracs at the same time, write notes like "take from E5 to B3", etc etc. It's a bit tedious but we rule lines across eac...

Re: nickel sulfate

We go by RiskAssess as well. CSIS hasn't been updated for decades, the Dept must be waiting for a legal case before they start?? It's bound to happen, one day, sadly.

Re: Free elements sets for schools

Re: chemical register

I am really surprised, I could not find anywhere that referred to open bottles, in the old paper version or the new online version. I have taken this from the revised online CSIS, FAQ section.

Any feedback, Marama T - is it working out? Sounds like a great idea! Hard work, but essential!

Wayne thanks for sharing, that method looks great! So much background detail as well :clap3:

Re: trundle wheel

I have just placed an order with MTA - Item NK10117-10K is for a set of 10 trundle wheels that look very sturdy. I also have 2 metal ones which are a lot stronger, but don't actually record the distance, there is just a click that you have to count. (I can't remember where I bought them.) So I also...

Re: trundle wheel

The blue and yellow plastic ones are terrible for falling apart. We have one here but also have two metal ones that seem to do a great job. These were bought by the previous labbie and I do know not long after he bought those, I couldn't source them for the school I was at at the time. Maybe someon...

URGENT Burettes needed for exam - Northern Sydney area

Help! A large number of our burettes have decided to give up the ghost - the day before the HSC assessment task :-( I am in the Chatswood area - can anyone lend us about 15 or so, I will collect them today (Tuesday) and return them on Thursday? The acrylic ones are obviously easier to transport but ...

Re: Risk Assessment

We have had RiskAssess for several years - but the main subscription only, not the student version. I don't know how I would have survived without it, especially for chemical labelling. Been the best thing ever. We've used the booking process for Senior Chem, it's worked a treat. For about 3 terms n...

Re: New CSIS is finally here.

Australian Independent Schools (AIS) also pay a subscription for us to use it. But Chemwatch wasn't designed for schools.
