Thank you

A friend is trying to find glass metal files, can any one help?

For our new members

What about silver waste from precipitation reactions? Classes are doing various precipitation reactions in spotting plates using silver nitrate, copper, barium and various other chemicals but they're only using a couple drops per spot plate. Surely this can just be washed down the sink? Or does it ...

It was a very large job, but we had a lady come in each Friday just to do the dropper bottles, she came for over 3 months, until every dropper bottle was done, then we got signed off from the CSIS, gosh must be 20 years ago now.

It used to be Luca's Heights, but not sure about today.

Well done again Bigmack

Yes 6 years ago yesterday, Chemtalk went off air for a long time. So may of us where lost (If you like that word) then WESTLAB purchased it. So Thank you very much Westlab for your purchase, it has never missed a beat since that day. :clap3: :clap3: The information in Chemtalk is the best. Well done...

Do not think poor sink & water ways, remember unless you are a new school (Newly built) you have a pit or sump where it is pumped out at a later time. See Principal for plans of the school or General Assistant GA.

Thank you Bigmack

Thank you Westlab

Good one Bigmack

Perhaps a near by school could help you out???

NO it was all taken out, Our Head told us because of insurance, display's where put into walls, with the Prep room at the back, display into the class room.

So true, shame we can not help local school's out

Correct, for NSW but I'm not too sure regarding QLD sorry Bigmack

Well said Bigmack, well said

Bicarbonate Sodium purchase from supermarkets, when the HCl stop fizzing it is neutralised, Then down the sink to waste

Enjoy Bigmack, they are very lucky to have you. A Man that is oh so good at fixing things.

Hope you are all keeping well, enjoy PFD day.
