    Spill Kits in Labs?

    I don't put spill kits in labs. I never give anything out in a quantity that would need the use of a spill kit so just keep one in each prep room for when I'm handling large quantities

    Ripple Tank MkIII Review

    It can't be projected easily with a visualiser, but if you lift the lid up in a darkened lab it will project onto the ceiling. Thats how we use it

    Better Equipped Alternatives

    We buy most of our supplies from SLS (science2education.co.uk). They are quite competitive with pricing anyway, but if you have a decent sized order it's worthwhile speaking to a rep.

    Plastic bottles for 1M HCl and other such things

    I've just bought hundreds of these from SLS although they are the narrow neck version: https://www.science2education.co.uk/product/BOT3826 They're cheaper than Better Equipped and if you have a large order, it's worth contacting a rep to see if you can get discount

    Protactinium Generators

    Thin Layer Chromatography (analgesics) - any tips?

    Just trialled this today- caffeine didn’t show up for me with iodine vapour but showed under UV light. I used 10:9:1 ethyl ethanoate:hexane:ethanoic acid and the aspirin just dissolved and didn’t show. Reduced the amount of ethyl ethanoate to 2:9:1 and it mostly worked although the deparation...
