Splashing it about

    Quote, a good one, " " Also it's not staff splashing it about that's the problem - I always make sure bottles go out almost empty because pupils don't seem to know difference between "a few drops" and "a good splash" """ got me remembering.

    In a previous existence we used smaller bottles because when a recipe says to use 50 ml and they got a 250 ml bottle, it always came back half empty, ditto for a recipe asking for 10 drops. We trialled sending out small amounts in the bottles and got complaints that there was not enough stuff for the experiments. Then we sent out the stuffs in 125 ml bottles and they came back the same, half empty, but no complaints. Cut our stock solutions usage by near half -- -- -- Result !

  2. Definitely - the more you give them, the more they will use.

  3. I call it 'portion control', when i get grumped at for being mean :D

  4. I am looking to put everything into smaller bottles mainly to cut down what I throw away due to lack of storage space.
  5. I give out things like benedicts in labelled 100ml beakers...one per pair/group and put in 20 ml if they need 10....otherwise each pair pours 80ml into their own 100ml beaker to use 10ml....if it's given out they feel the need for a full beaker each.......
  6. I'm in the process of downsizing as many of our experiments as possible ie, micro-science and then when they need less than 20ml I give them an eye drop bottle. With expts that require larger amounts I never fill the bottles they get what they need plus 20%.
  7. Not something I can or want to influence. They want 500ml of x or y and they get it. Waste and environmental impact is their conscience not mine.

    I am gradually buying 125ml flasks so that I can store more class sets of chemicals. Easier to carry up and down the stairs too especially when numerous metal solutions are needed at once.
  9. I always put out a small amount in bottles/tubs and make it clear there is enough for all and there isn't anymore. They are starting to learn, slowly. I don't think it helps that some staff don't know the chemicals, especially indicators and assume the more you put in the better, hey ho
