Re: Dry Ice SDS

I think a little common-sense is necessary. The inherent dangers of a large amount of dry ice is vastly different to 1kg in an esky. I have to drive about 4 km to pick up the dry ice and then quite happily drive back to school with it in a 6pack esky in the back of a station wagon. About 5 min. Ther...

We buy the plates in bulk cartoons of 500 plates and use a plain agar /nutrient agar mix. This is my breakdown Cost of Agar Plates Each plate costs $0.16 Have to use 20 plates $...

Re: labeling old chemicals in store

I can't see anything there that says the old labels should be covered. My experience with the original labelling following the CSIS was that incorrect labels were affixed to bottles, probably all in good faith by inexperienced people. Maybe picking up the wrong bottle, the label belonged to another ...

Re: Risk Assess and labels

We don't use Risk Assess.
What I wonder is, when we haven't received the upgraded CSIS or any other information from the Department regarding different classifications, are the Risk Assess user group classifications what will be in the upgraded CSIS or his own classifications.

Re: pH solution

For this prac we just use HCl 0.05 M which has a molarity about 2.4 HCl 0.01 M which came in about 4.34 Distilled water 6.5 NaOH 0.01M 9.03 NaOH 0.05 M 11.9 The idea is to show that different pH will affect the action of an enzyme. It didn't really matter if the pH was not exactly 3,5,7,9,and 11. Th...

Re: labeling old chemicals in store

I also have made my own templates that are the size of a J8165 Avery label. I make sure if possible that the new label does not occlude the old label with the chemicals name on it so the person using the chemical can be sure that the new label is correct just with the updated information. I have not...
