Both appear to be available at a price of $39/$35 for only 25 mls.
My thought is too expensive for limited use

My thought to only for one student. Thanks

I love my two Bio teachers, yr. 11 River Red gums and wetlands ecosystems, two full days out the river and to local wetlands taking water sample and looking for bugs yeah.

Thanks for that.

Yep Round up is becoming an issue.

Hi Brains trust,

I have a student wanting use Nonanoic acid and Heptanoic acid in a depth study doing Esters. According to Risk Assess they can use, however does anyone know where I can order from? Or are they stocked under another name?

Thanks in advance

Hi Everyone, My HT has come to me with a list of equipment from NESA that is apparently needed to complete the HSC Chemistry course. If anyone can help me out with suppliers or alternative equipment that will do the same thing. I have the majority on the list and some that can be purchased from West...

I think it was part of a prac in the old chem curriculum??

The same with Potassium Fluoride anything above 0.43M solutions is 11-12. I love RiskAssess

Waiting for approval, hope to see everyone there.

It's really scary how it works with Asbestos, if you are diagnosed, because of the class actions taken the major unnamed company will pay out the claim, then there insurance company goes through all your employment history to re cope the funds.

Hi Estelleaf This has concerned me for years, there were years prior to SDS and the internet where we had little to no information regarding storage, use and disposal of chemicals. I have noticed over the years I have become more sensitive to different chemicals. Days I have spent in and out of the ...

Hi,

Wondering if anyone can help me out looking for 1000 ml or greater interchangeable distillation flasks. Looking for a supplier also is there any restrictions or legislation regarding the purchase of larger equipment (as with certain chemicals)?

Hope that makes sense.

thank you, Bigmack

Morning, Just after some information on a small industrial distillation Unit, are we allowed to have on school premises and if so does it have to be set up outside? Would it be considered a pressure unit needing someone with a pressure certificate to install? As far as I'm aware it is being used to ...

I do warm soapy water, dry and store in foil lined trays. stops them rusting.

This new year 12 Chemistry pracs are doing my head in, great to have a challenge, from chemicals kids aren't to use and shouldn't be using, to mind reading some of it. NOW asking for 5 x 10-4molL-1 iron (III) thiocyanate = 0.0005m is that right? hate looking like an idiot! Practical investigation of...

Yep Melsid, it's the following prac. cobalt chloride equilibrium system prac. that uses the HCl. the reversible Reactions is the one with Colbalt chloride solid teacher only according to risk assess, I apologise that was my original question. One problem is what the teacher believes!!!! lol. then te...

Just looking at the cobalt chloride equilibrium system prac. 11-12 can use 0.5M Cobalt Chloride, and if you have a look on riskassess 11-12 hydrochloric acid 8-10 M (25-32% wt/wt) teacher only hydrochloric acid, 10-12 M (32-37% wt/wt), concentrated. If you do a label for 10M HCL using riskassess it ...
