Hi All,

I was wondering how you cut the agar 2cmx2cm, 1cmx1cm and .5cmx.5cm cubed. Is there a special technique as mine seems too crack or is never the right size when I cut them with a scalpel.
Any help would be greatly appreciated.

Thanks Superbug

Hi I have been told that the microwave is not a good option as it doesn't get hot enough to kill the microbes. we are now using a pressure cooker as an autoclave (used with autoclave tape).

Thanks Superbug

all the time until the motor blows up.

Hi Again,

Our WHS meeting is on tomorrow and I am still unable to locate anywhere in the workcover website as too where it states that We need a flammable storage cupboard for maintenance chemicals. Any help would be very much appreciated.

Thanks Lis,

We place them in labelled paper bags and dry in oven over a few days and the students measure the weight before and after drying without taking items out of paper bag. then we dispose of the bags with contents inside.

Hope that may be of some use.

BOC does not supply dry ice in sydney anymore or at least our local one doesn't as I found out recently oh and they dont deliver either.
