Thank you mtg -

I have found putting them in metho works really well... except now we are told that we cannot put anything flammable into a fridge - so.... brains need to be in fridge but what do I do with brains in metho??????

Does anyone still use this - is it still available? what do you think of it?

We have been upgrading since we heard about GHS at the ASET conference quite a few years ago - it takes time to do it, while still keeping up with prac work. All our chemicals drop bottles etc are GHS now, and I have just completed the Hazard register for the whole school - GHS compliant

I melted it in an evap dish and had made a long tube out of alfoil and poured it in. When cold then it can be used for conductivity

it is the hammer that did it!
I have heard the old builders saying
"Hit it with a hammer" works every time

I have heard it is not safe to store in fridge - but we do. I think the lower concentrations that we use -6% - is quite safe in there.
No fridge is sealed completely perfectly so any gas release would not build up in the fridge.

maybe throw them out and charge teacher for the cost of new ones- do NOT put yourself at risk of broken glass by trying to clean them out..

Moree is about 1 hr 20 minutes drive from Mungindi - if you are not a local.. I wont tell you the time it takes for locals to do the trip! The railway used to go all the way into Mungindi but the station was washed away in a flood and never replaced which is a shame..

Mungindi - has a hospital! It is on the border between Qld and NSW and the river is the border. The hospital is on Qld side and has airfield right next door for immediate medivac to Brisbane if required, also has a nursing home attached. There is one GP and a pharmacy. two coffee shops - one of whic...

In the long run it would be cheaper to bu another set of textbooks to stay on the level that they are required.

First off I am going to Mungindi NSW to have a look at a house I may be able to afford to buy.. maybe. I was planning on retiring there because I can rent a house at low rental and afford to live on the pension, but a house is on sale at a little above the value of all my superannuation - so hoping ...

??? Well this is a new lone for me.. to do biuret test we just use drops of 0.25M copper sulfate and then 1M NAOH .. is the test different to the reagent?

sorry - not here

It depends on what they have been used for. Mostly you can rinse well in clean water then final rinse with distilled water. If I need to, I soak in detergent and water then rinse. The bulbs are tricky. You can fill them up with water and push the water out a few times to rinse all the valves, then s...

we use them for one week a year only

I also store them upright - bought plastic pasta storage jars - cheap - put a chux folded up in the bottom and each lab has them on the sink, Lens are not used much here so I boxed them instead of using a whole drawer for them Balances - digital ones I bought containers from Reject Shop [$4} and sto...

I HATE cleaning beakers after this prac...

Cargo van - NO GO, station wagon - NO GO the reason is for the drivers safety - Dry ice is made of CO2 and when it "melts", it becomes CO2 gas straight away without leaving any wet mark (that is why it is called dry ice). CO2 is easier to be tied up in our blood and thus, when the dry ice ...

I was using them in rooms that did not have gas connected.. I have now had to buy the portable bunsen burners as you have agregory - and they work well, then I had to buy the taller tripods to go over them!
