Hi All,
it's been a while since we talked.
Does anyone have a system for dispensing hydrogn peroxide to classes?
I favour the containers they come in with the paper valve on top.
When we use dropper bottles the teat swells dangerously....

Hi All,
the people at Walchope where we bought our bar magnets years ago, have a service where they re-magnetise them, paint them and supply new spacers and keepers if needed. All at a very reasonable price,

Hi Mary,
I have recommended John Reed, many times but you would need to check with him about microscopes. Having said that he helped us out. I can PM you with the details if you would like?
Cheers,

Hello all, it seems there is nothing that makes such beautiful esters as butyric acid. Has anyone some ideas how to store this horrible stuff? At present I have it in the 25mL bottles it came in, inside a self-seal plastic bag, inside a glass jar, inside another glass jar, inside the corrosive cupbo...

a dot of Supa glue??
It's a loooooong time since we used ours - I think the teachers have forgotten about it...

Hi Lita,
we have a mobile repairer with us at the moment who does all those types of repairs. I'll PM you his details

Thanks Sue,
very worthwhile tips - Southern Biological are a tad expensive but we don't need many and the Wetherill Park people are going to send me a catalogue. Thanks again,
Cheers,

Sorry, all my contact for re-supply of rocks and minerals is not responding to many mobile phone calls. Maybe he has lost his phone? I know he has moved but I know not where. I will continue trying but in the meantime, home-made malachite may be the way. We have made our own in the past and it works...

Hi All,
does anyone remember the storage bottles, perfect for displaying mice, frogs, etc that are the old oyster bottle style? I would like to purchase some more for our biological specimens and any any help with a supplier would be appreciated.
Cheers,

Hi y'all, I have a teacher dissatisfied with the sheep brains we supply for dissections. Sometimes no cerebellum /pituitary glands....also the size is a bit small. The local abattoir is not interested in supplying anything bigger than sheep. Does anyone know of a supplier of something big (cow?) wit...

Thank you all, lots of good tips there. We'll just keep working on it............

Hi All,
has anyone been inspected and can give us tips on what the inspectors look for in prep rooms, labs, etc from the OH&S point of view??

Hi All, just an update....
I dropped past Franks place in Turramurra yesterday to see if he was still in business.
He has moved but I have a contact phone number - just waiting for him to reply.
Cheers,
~Robyn

G'day again,
the mans number does not answer. Maybe he has retired.
I am over that way tomorrow, so I will call in and get an update.
I'll keep you posted,
Vheers,

Hello Robyn (nice name) you have a very nice guy near you in Turramurra. I hope he is still in business. He runs Geological Specimen Supplies and can supply re-fills and bulk orders for the Students Geological Specimen Sets we all have. We get bulk malachite from him when necessary I can PM you his ...

Hi Annette,

Hi Julie,
we have a Greenleaf Farm Lab kit which I don't think we have ever used.
I pulled it out and there are sheets labelled 'Confidential - Preparation of reagents for schools'.
I can fax it to you if you would like,

~Robyn

Hi corurtney,
I have just noticed that Serrata seem to have the lenses you require...........
Cheers,

Hi Lisa, we are about to get a service from Mechatronics who supplied our nine fume cupboards last year when outfitting our new Science building. At an OH&S Inservice last year I learnt that it is ideal to have the fume cupboards serviced twice a year but we are seeing how it goes with a contrac...

Hi Lisa, last time we went for the cheaper ones that were Schott look-alikes but were Chinese in manufacture. Whilst this is a good alternative for many things, we have decided NOT to go for the cheaper ones in this at least in future only because they do not pour or seal well. ie - they drip when t...
