Hi All,

It is great to see this level of professionalism brought in to the position for the School Lab Managers. I trust this will be a great move towards setting some standards amongst us and providing the relevant support the position brings.

Well done.

Hi All, I would make sure the gas is turned off personally, and I do this in fact. Look at it this way, if ever workcover come in due to a serious accident then you can cover yourself and the Science faculty by at least having noted that the gas was turned off. This way any negligence will be put ba...

Set this up in a large box flat on a table, have a hole in the top to feed the lamp adapter in the top and connect the light from the inside of the box turn it on and there you have ...

Once I had posted a pH electrode ReJuvenation process which is very effective for the stubborn pH meters that don't give accurate readings. pH meters rely on transfering current across the ISE (Ion Selective Electrode), ( Glass Bulb on the end ) so real...

Hi All,

Any Chemical Supplier will be able to source this for you.

Ask for 3-Aminophthalhydrazide. (Luminol)

Cheers,

Hi All,

Confirmation is accurate?......

Cheers,

Hi All,

Luminol is your best bet. At least Luminol will pick up traces on amino acids in your skin oils.

Place inferprints on Chromatography paper and they will turn Purple.

Hi All,

Just to reiterate,

Dichloromethane is the best option here,

Hi Lurra,

Great name change.
