Hi everyone

Our very old CSIS Bible gives ammonium nitrate an orange code. However it also says < 5% is non hazardous. Chemwatch also describes 0.5M as non hazardous. My question is can a 0.1M solution be given a green sticker?

Thanks in advance

Hi all Has anyone done Traffic Light Oscillations using indigo carmine? We do not have indigo carmine and I am wondering if there is an alternative indicator we could use to produce the same effect? We will be doing the bluebottle using methylene blue - just looking for something else. Thanks Kathry...

What would even be the point of disinfecting before the dissection!!! The stuff they are dissecting is not sterile! Waste of time!

I am the WHS people in our school and supposedly the expert on chemical safety! I have had a look at the "Labelling of Workplace Hazardous Chemicals Code of Practice" from Worksafe NSW as suggested by Merilyn. Personally I don't think the Riskassess labels satisfy the legal requirements ac...

Thanks. I'll give them a call. I'll be interested to know what you think of the preserved ones.

At the same time as relabelling solutions I have been trying to relabel some of the original bottles. I have managed to get a trial of Riskassess so I can see what you are all raving about. However, look at the difference between the labels for Silver nitrate (they both had the pictograms): Chemwatc...

Hi
Anyone from the Wollongong area have a local source for eyeballs? I usually get them from Dissection Connection but trying to cut back on the delivery charge.

Thanks linotas.

Unfortunately I do not have access to Riskassess atm. I'm feeling very frustrated and wasting so much time trying to do labels. di-SODIUM HYDROGEN ORTHOPHOSPHATE on Chemwatch this is described as hazardous with a signal word of Warning. On the Chemsupply site it is described as non hazardous and no ...

Would it be useful for those who don't use Riskassess?

Sorry but I think it would be irresponsible as well as illegal to just put it into landfill if it is suspected of containing asbestos.

We have Moh's kits dating back from before I started working here - so at least 10 years old. They are most probably from Serrata. What are most peoples thoughts on whether these should be disposed of - and if so how to go about it?

Hi everyone

I need to purchase another soil pH meter. We currently have a Kelway meter which I don't think is particularly user friendly. Does anyone have a suggestion for an easier meter to use?
Thanks

Could you please send me the conference details...

With Science week coming up and the theme being light, I decided to check out the DIY hologram link which has been doing the rounds lately. It is so good! Very exciting when something like that works so well \:D/ The instructions say to use an old CD case to make the rhombus. I wanted something the ...

Hi all

I am looking to buy a new dishwasher this year. Our budget is unlikely to extend to specific laboratory models. can anyone recommend a brand / model that they have found to be good in a lab setting?
Thanks
Kathryn

Are the lenses magnetic as well?

Thanks everyone - I think unless we can get a discount rate, we will not renew our subscription. Labbie - I find that unusual that Chemwatch has something as non-hazardous when the manufacturer had it as hazardous. I've usually found Chemwatch to err far to much on the side of caution and label thin...

As we are not a government school nor do we belong to the Independent Schools Assoc, we have a huge bill annual for Chemwatch. I am wondering what other schools do in our situation and if there is any cheaper alternative to Chemwatch?

Lucky me is planning to take some LSL term 2 of next year - yippee! We are looking for someone to work some of my hours while I am away, so that the labs won't be a complete disaster when I get back!! It would be for weeks 1- 4 in term 2 and about 15hrs per week. The hours would be spread over 3 day...
