Does anyone who is not on holidays have an MSDS for unleaded petroloeum and two stroke unleaded petroleum? My Senior Chem teacher just bough me a bottle of each and had asked me to label and store them untill he needs em hmmmm first day back though it was going to be a lovely lazy day damn!

Yeah i just print them out double sided to begin with

our labs have an isolation valve in each room, for each room that requires a key to access.I also have one in my prep room ( which only has 2 gas outlets as oppose to the 16 in each class) along with the emergency shut offs.

Ours is a fluro which is compleatly sealed in a big glass case thing

just wanted to show my magnificent crystal growing ability. I prepared these to show the year 7 class befor they start to grow their own. The one on the left is two weeks old and the one on the right is only one week ahhh my babies I want them to be monsters! :crazy: oh and thats a 5c piece just for...

Well we emailed them last week and got all our stuff yesterday !!!! Now I just need to figure out what it all is and what it's suppose to do

The exhaust in my chem store is on 24/7 and has no switch to turn it off. In fact cemented (flush with the floor) into the floor right infront of the door is a plaque that says Chemical Storage WARNING Flashing Strobe Light Indicates Exhaust Fan Failure and I even have the strobe light on the ceilin...

I would try dissolving the milk powder into a bit of warm water first and adding that to your agar

forgive my ignorance but whats a pluck?

Science and Technology Education Leveraging Relevance (STELR). Is a national programm funded by federal gov.
"The STELR Stage One Project supports the proposed National Science Curriculum" supposedly
www.stelr.org.au for more info

has anyone elses school signed up for this programm? We have but still have not recieved the equiptment that was promised in february. The teachers were sent on their PD courses for it back in march, but we still don't have the resources that go with the programm. Has anyone else got their stuff yet?

I just check my bromothmol blue powder and it is pink, is that normal. I have nevr used it befor so I dont know what to expect. Only got the bottle end of last year.

If you do a search for crystal growing a whole bunch of stuff comes up.

Thanks guys. I made a whole heap of them yesterday turned out really well but then had a brain fart and started to question myself!

How much agar do i need to per plate? just enough to cover the bottom(about 3mm up the side of the dish) or do I need more (say 5mm)?

they have a picture of an evapourating dish under the heading of measuring cylinder. I'm glad I still have the freedome to use what ever supplier I want

Have managed to separate them into class size lumps, the teacher who needs them lives next door to the school so he has said he will come in on monday and take his batch out of the freezer. the rest can wait for defrosting till next week

HI!, I have just picked up a very large block of frozen hearts from our local butcher. Now I have a question about how long I can keep them for. The dissection pracs are set for tuesday, wednesday and thursday next , now my problem is that because they are all frozen in a big lump and this weekend i...

thanks it's my first day back lol!

probably a simple question but is NH₃ the same asHNO₃ nitric acid?
