I would have said all that too Bec, I was eating and typing one handed...

plastics for agar, buy them sterile from westlab

I just run mine under the tap for a while, then wipe dry with paper towel, then dispose of the paper towel. I wear my goggles and an apron / gloves when I do this.

Thanks Merilyn and Sunray and Linotas.
I have some nichrome - will try, and I have the thin glass too. JAYCAR sell nichrome fairly cheaply too.

I'll put it on the list for the days 'i play science'

Although flame test isn't in our program any more for juniors, there is a component in the yr 12 chem program. Teacher is set on flame test loops - (for jnrs I have done all sorts of things) Have been looking at suppliers, but have found nichrome at 11.90 EACH! and they degrade so quickly. I have al...

Thanks for sharing the DET school Biz links, I cam here to do just that.

So we can all relax and do our jobs.

Thanks Labbie, I was in Melbourne this weekend for a weekend of R&R, and then the :hitthefan: with the weather along with a list of other things going wrong that husband had to deal with without me! Our garage was completely covered in 4cm of water - thats going to be a fun day to clean all that...

I had boxes of previous prac orders, taking up precious space - I binned them all last term.

you'd think that would be covered in the teachers keeping the register records that they sign off each topic / dot point?

I just say ' its food grade, i bought it from a butcher, wash your hands when you finish" (they wear gloves). And I rinse and put everything thru the dishwasher. I WILL not hand wash scalpels - its an increase risk of injury!!!

We have enough to do without that extra step!

I'm still learning how to edit them.
You have to self teach everything these days.
Its amazing what I have taught myself, Chemwatch is not the easiest thing I am finding though.

sorry 0.1 of sulphuric, not NaOh

when i looked up 0.1M of NaOh this morning the label is blank too, so in GHS there is nothing to report on this chemical?
So I can just print a blank label with the name on it?

I sweep the floor once a term, but there are cobwebs up high with accumulated dust, but i'm not cleaning that. Thats too high for me. I just the area tidy

maybe next week...LOL
I think my labels would say
"dont drink it, sniff it or put it on your skin"

yea i am a goose, found it - all good.

I expect this behaviour of my brain on a monday - or friday LOL

I just thought I would do one chemical today to get started on the GHS labelling. Logged into chemwatch and got 'sodium hydroxide', and the labels are not the GHS ones. They are the old system ones. The pictogram is the old one. So I checked copper sulfate, knowing that the pictogram should be the d...

I am going into GHS prep over this year. I have added a column to my chemical stocktake document, beside the SDS date one, so when I do the new label I can tick it off so I know where I am up to. AND, if we get an audit, I can show that it is 'in progress' BUT I also think that the CSIS review shoul...

I had the weaker solution in the fridge and the stronger one locked away in a cool spot in the chemstore.
But now it is all in the chemstore it gets really cold in there in winter

yep, was going to suggest re-heating.
have a little fun yourself!
