Hi All,

Just wondering if anyone knows where I should store dichloromethane? I have safe handling and disposal details, but for storage all I can find, is in glass and kept away from light? So should I just put in on the "Toxic" shelf??

Cheers MariaQ

Hi All, Since posting this, Ive found an answer, Serrata now sell silicon teats that replace the rubber ones, at a cost of $3.00 for 10, why they didnt tell me this yesterday when I was talking to them about the rubber ones is beyond me #-o anyway being silicon they should last a bit longer, cheers ...

Hi All, I have hundreds and hundreds of dropper bottles with droppers and rubber teats, most of our chemicals go out into the labs this way. Now Serrata have stopped selling the rubber teat, and or the dropper assembly separately so effectively when the rubber perishes I have to buy the whole new bo...

Yes Merilyn1, thats my point, it is a great experience I have done it before, but Im not being paid and everyone else is. I get my pay averaged, but this does not mean Im being paid for that time.

Hi Just wondering if anyone goes overseas on school tours in their holidays? And if so as we are stood down, do you get paid? In fact does anyone work in the stand down time and get paid for it?

I think we all have a duty of care, so you would follow CSIS, unless you have more current information that contradicts CSIS. Borax is one of a few chemicals that is now deemed more dangerous than previously, with that knowledge in hand you cannot ignore it. You would not be able to stand up in a co...

I was wondering if any other school had purchased this, and if they found it useful or not?

Thanks for any feedback

Conc sulfuric acid is teacher only, give the teacher a bottle and a disposal plastic pipette.

Cheers MariaQ

No offense, but isn't it the teachers job to find this out, not ours! I hate to tell them something and it be incorrect. Not our responsibility.

And what about storage requirements???

They start out with 5ml of solution!

:thumbup: We call it whose got ebola!! 0.001M HCl, 0.1M NaOH as the diseased sample, and phenol red for indicator. They have droppers, swap 1ml with three other people, put in the indicator, infected pink, non infected yellow. Then they try to work out by who swapped with who, which one was diseased...

Correct me if Im wrong, but i also believe the "new" GHS labels are for "use" only, that it when goes out in the lab for use, but storage is still the same as pre GHS, or has there been an update to this? MariaQ

Thanks Merilyn1, I had already considered that, otherwise they would be massively long! putting my order in. MariaQ

Thanks all for the feedback, you've helped me make up my mind to buy them!
