Independent School. I looked up Coles homebrand. Their SDS is linked to Chemwatch hence the 12 pages (for non-acetone).

I was told in one rego inspection that even the non toxic paints which can be used by preschoolers and even though the ar...

Lots of chemicals have changed - some going to a higher classification and some going down. One that I am fin...

Re: Pasteur Experiment

The dreaded Pasteur experiment! Do others filter your broth? My teacher likes it to be clear but it takes absolutely forever! This year I am trying Continental Stock Broth in little pottles.

Re: Do we have to keep exhaust fan on 24/7

Ours is on a timer which comes on about 7am - til 6pm. However, what do people do about flammable cupboards etc? It is located inside the chemical store but when I open the door to the flammable cupboard I am just about knocked over backwards from the fumes!

Re: Pasco WiFi pH sensors - buffer solution

Prima, could you please tell me about the Pasco probe - is it an independent unit or does it have to connect to a data logger? Could you please tell me where you purchased it from and the price?
Thanks
