Hi all

Sorry this reply is a bit late but I'm sure I read in a previous post early this year or late last year that soaking in honey work!!
Can any one else remember or comment on this?
Someone's hubby was a beekeeper or some such thing.

Hi Tammie
Why don't you just make up 10g in 100ml for glucose and 20g in 100ml for salt?

Do you actually need the molarity?

Just a quick update.
Just spoke to SSA they no longer sell this either. Apparently it has a new classification.

What does PTU taste like? When and where would you use it? I think it has a bitter taste and is used in genetic testing. Apparently you inherit the ability to taste the bitterness or PTU or not. It is linked with the ability to taste the bitterness of certain foods. It is also used to treat certain...

Hi All,

One of our teachers has just asked for Phenylthiourea(PTU) to do taste tests. Apparently some people can taste it and others can't.
Does anyone know a substitute for this that would have the same effect?
PTU costs $182/25g ,he's got to be kidding!!

Thanks

Hi! How recently did you buy it and where did you get it from?? I ordered some recently from Serrata but was not supplied with it. They no longer stock it. When I contacted Silform chemicals the gentleman I spoke to said that no matter what quantity you buy, you require separate licences to buy it, ...

Hi All, Well I'm now totally confused. Where are there a CLEAR set of guidelines simply written and available to everyone that states what where when and how?? Does the DET CSIS folder have all the required information that we should follow? Is it different for all States? This topic is one HUGE can...

I thought BRUT or OLD SPICE was the go!! I think I'm showing my age!!

Hi all, I think it is a lost cause. I've just checked the Chem-supply website and there was no listing for this chemical. I also spoken to a lovely gentleman from Silform and he informed me that they will probalbly no longer carry this chemical. The government require individual licences for importi...

Serrata no longer supply this chemical. I actually tried ordering through them and spoke to them on the phone. They are no longer allowed to supply it.

Hi All, I'm looking at updating the shelving in our Chemstore. Does anyone know of the exact requirements for chemical shelving or where I can find this information? Does anyone know of companies that supply the correct shelving? Any other information regarding chemstore shelving would be appreciate...

Hi Pommy, I did a major clean of ours a couple of weeks ago. I used brasso and this worked really well. The instruction manual actually said not to use anything too abrasive on the suface as you don't want to scratch it. I also pulled the whole thing apart to clean the rollers too. The other thing t...

Hi all

Hi Joh,

Hi All Thanks for your replies. I spoke to Eddie Bishop re the CRO (not the Crow HA HA). We seem to have ironed out the problem. Just incorrect settings on all the dials and knobs, along with me being totally inexperienced. Seems to be working really well now. The physics teachers was HAPPY!! YAY!! ...

Thanks for the tip. I'll look into it
We are also using it with a wave lab, one day we had signal and the next day nothing!! The frustration!! I'm not very good at physics stuff so it adds to the challenge!!

Lorrae

Hi All,

Any ideas of a repairer for a CRO??


Thanks Lorrae
