The next question I have is, how do you get the Nitrgen dioxide?

Hello Chemtalk family, I was wondering if anyone could help me with an experiment/demonstration for Le Chatelier's Principle? My boss said he had done it years ago but couldn't exactly remember the details anymore, and being only new to this I haven't got the foggiest. Please can anyone help? Many t...

Just keep it coming! I find it all very intersting as does some of the teachers here who are interested in astronomy.
Thanks Rob for expanding my universe!

Hi everyone, I have just obtained a replacement belt for our older IEC model VDG by dealing directly with IEC. They have a website which has a section on technical information. Unfortunately the PDF document didn't work on VDG but they were able to send me a document on belt information such as a su...

Hi Lada,
Thanks very much for the prac. As it turns, out my boss said the one he used wasn't very successful and was grateful to see yours.
Cheers,
Lou P.

Hey Lada,
I would appreciate a copy of the prac. Our fax number here is (02) 69225659. Just mark it as ATTENTION: Louise
Many thanks,
Lou P.

We bought ours from Science Supply Australia.

Their website is http://www.chemtalk.com.au/viewtopic.php?f=26&t=451

Hope this helps,

Many thanks Ian. I love learning things, I now look forward to putting this knowledge into practise!
Cheers and beers,

I was fortunate enough to have had the help of a lab technician to show me how to bend tubing (still wearing "L" plates)... but I never found out how to flame polish the ends of glass rods. Can anyone tell me how?
Thanks,

Hi Ian and Louie, I, too, am only 18 months into this job and had no idea what these type of crucibles were until I was asked to price them late last year! Sintered glassware is used for the filtration of liquid and gases. It incorporates a porous glass disc as a filter media which is non-corrosive ...

Thanks everyone, I shall go forth and invesigate these models. You all really have been a great help.
Cheers, Lou P.

Good Morning Chemtalk Family,
I was wondering if anyone could recommend a way to clean sintered glass gooch type crucibles of a porosity of 3? They were used to quantitatively determine the amount of sulfates in fertiliser.
Thanks in advance for any help,
Regards,
Lou P.

Good morning Richard! Thanks for your reply. Could I ask where did you get your dishwashers from and how did you get the racks specially for lab glassware? Do you know the amount of water used in a cycle? What do you use for powder? And (please excuse my ignorance) where does "Slartibartfast&qu...

Hi Everybody! I was wondering if any of you use a dishwasher and if so what sort is it and do you have any recommendations on what to look for and stuff like that. As my school is only four years old, the upper echilons had allowed for a dishwasher in my prep room and have decided (after me cutting ...

Hey Robbie, The phosphoric acid is part of the recipe given in "The Laboratory" for an extraction solution. I didn't read down far enough to see just the solution recipe. Regardless, CSIS rates DCPIP solution as a year 11-12 use only. I think the Starch/Iodine/Vit C experiment given by Mot...

Hi y'all, Our cleaners are supposed to maintain the floors, sinks, desks and windows and I maintain the equipment. Because ours is a new school my boss likes to have the labs maintained at a high standard all the time so I often clean desks, benches, sinks and windows AND maintain the equipment. I d...

Hi! I buy digital scales from Big W at a cost of approx. $24 each. They have the capacity up to 2kg and 1g graduation. These are powered by 2 AA batteries, automatically zeros when turned on and tare can be reset to allow for separate weighing of items as they are added to the scale. Oh! and they au...

Thanks Julie! Received your fax yesterday, great work!
We are looking forward to giving your recipe a go. Also we have enjoyed the fact that someone has an "8S6" to survive, as don't we all!
Lou P.

Would you mind sending it to me too ?
My fax number is 69225659 and if you mark to "Attn: Louise - Science" I'd be very grateful.
Thanks,
Lou P.

Hi Chemtalk family, One of the teachers here wish to do the experiment where a funnel and a test tube is inverted over elodea placed in a solution of sodium hydrogen carbonate to catch the gases. Elodea is not available around here. Can anyone suggest an alternative water plant to use instead? Regar...
