Hi everyone, Just a question for those who are using the STUHL plastic dropper bottles. Do you keep all chemicals in these or do you keep your iodine's,universal indicators and stains in amber dropper bottles?
TIA

I use Nalgene plastic bottles for most dilute chemicals. These fit into unitrays perfectly for 30 ml and 60 ml bottles

Iodine solutions and organics I place in amber bottles with glass pipettes.

There are charts available to tell you which plastics are compatible with which chemicals . In the Laboratory book available from southern biological.

Regards

Where do you source your bottles from? I am finding the dropper bottles seem to now be a wider bottle which does not fit in the unitrays.

We use a mixture of both glass and plastic dropper bottles. The only chemical that is a must for me with the amber glass bottles is Silver Nitrate and Iodine Solutions. '
I have got my plastic bottles from both MTA and Westlab.

Hi Kathryn
I get my bottles from Southern Biological

I get mine from Hains Educational

I get my Nalgene bottles from Science Supply (Vic company), the Nalgenes fit perfectly in the unitrays :

You can also get bottles that look exactly like the Nalgenes, much cheaper but they are slightly wider and don't fit quite as well in the unitrays.
