Re: spikk kits

Re: Water bath
I just set up a tank I think the temperature range you could set it to was 18-30.
You can get heater thermastat combinations for aquariums made of metal now which might last a bit longer than the glass ones.

Re: Phenolphthalein Agar
We have always cooked up agar and phenolphthalien, then the cubes are put in a dilute sodium hydroxide solution to turn pink.
Very easy, never had any complaints.

Re: making solutions
I think it depends on your water quality.
I work at two schools, at one I use tap water and have no problems.

which is bore water, so I have to use ditilled water.

Re: marking glassware
I haven't tried marking glass but I colour-coded all the labels on trays of equipment -a different colour for each lab and prep room.
Of course it doesn't mean things are always put away but anything out of place stands out.
