Re: Free elements sets for schools
Since these element sets are my babies, let me put up a few quick answers to some of the queries here. 1. Firstly, PLEASE look at the website (elementsets.net), and in particular, the Teachers' Notes available there (updated recently; these are different to the booklet contained in the set). These ...

Re: Free elements sets for schools
I did have a thought afterwards. We put some mercury switches into these containers - tiny amount of mercury (so tiny, I couldn't really see the point). I decided to glue the lids shut and I had the casual use a really small dot of superglue to do so. That was twelve months ago and they are still f...

Re: Dissolved CO2 Sensor
Yes we use these all the time and have a class set. We used then on a regular basis for CO2 gas and probably 4 times per year for dissolved. So we only purchased 5 sleeves for our sensors. They are so easy to use and have very good repeatable results. If you have the cash, a good investment. You run...

Re: GelRed Nucleic Acid Gel Stain
Very specific.... can you use a different stain ?. New England BioLabs would be the people I would contact. https://www.neb.com/en-au They also offer small samples so you could try.

Re: Chemical disposal
Excellent work, thanks for raising this. Just a good reminder to check everything . My biggest bill for waste was 2.5K one year and it was an epic clean out of old and nasty crap, 10 years of hoarding by previous staff ...... I think I'd die if I saw a 5K bill for a general clean out.
