Re: Potassium Permanganate Disposal
Hi all Looking for updated advice on potassium permanganate disposal. I have followed the Science Assist recommendations of adding 2M sulfuric acid then 10% sodium bisulfate but the colour has hardly reduced. So now I have gone from having 250mls 0.1M pot. permanganate to having about 2L - still dar...

Re: Hazardous Chemical Register
I have a soft copy SDS for hand sanitiser and list it in the register. However I don't provide a copy of the SDS in every classroom. For things like flyspray, I now choose to have the SDS for one brand and let that cover all brands. I can't see I am ever going to get staff to only purchase one brand...

Re: Hazardous Chemical Register
I do the chemical registers for the whole school. We have a company trying to persuade us to purchase their software for this (not going to happen) however they are saying there is a $3000 fine for any SDS missing and that things like toner cartridges need to be included. I have never thought about ...

Re: Catalase Solution Concentration
Hi. I am opening an ancient post. The students are going to do an experiment this week looking at the catalase reaction with 6% hydrogen peroxide and comparing to manganese dioxide as an inorganic catalyst. Has anyone done this using Southern Bio catalase? I am wondering what dilution of the catalas...

Re: ferric nitrate?
Yes Riskassess has it as 5.1 and so does the original container which is why I am reluctant to move it out of Oxidisers.

ferric nitrate?
Hi all Just started the annual chemical inventory and SDS update and have noticed a discrepancy in ferric nitrate classification. The original container (which is old) and Riskassess class it as DG 5.1 whereas the SDS has it as DG8. It has always been stored with the other oxidisers but now I am not...

Re: Automatically Logging Out
I keep getting logged out as well - for instance just then when I clicked on the reply button. Gets tiresome.

Unusual fungi
Hi all Looking for suggestions as to what an unusual fungi might be. (Sorry I don't have a photo.) It was a dark colour but had a very metallic sheen to it. Definitely fungi and just on our normal nutrient agar. The swab was just taken from somewhere within the lab. Never seen anything like it befor...

Re: Electrophoresis Kits
We have the Hexogel Electrophoresis unit from STEM Reactor. Can run 6 gels at the same time. We have been very happy with the unit and with the service from STEM reactor. Mostly we do the candy dye extraction but once per year we get in one of the DNA simulation kits.

Re: Incubator or oven
We have ordered an new incubator for next year. Our Thermoline has given up after 20yrs service. Repair was going to cost approx $800. We had the 43L but have decided to go to the next size up, 80L. Getting a Thermoline again.

Re: iron standard solutions
Managed to find the calculations from last year - it is more complicated than just weighing out a percentage as they have to be made from combining potassium thiocyanate and iron nitrate. If anyone is interested I will put up what I am doing.

Re: Plastic dropper bottles
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.

Re: What is the name of your roles
I always describe myself as a science technician - as far as I am concerned I have the qualifications and are far more than an assistant!

thanks for your replies. Unfortunately our budget will not allow a class set to be purchased all at once.
