Media Making Tips and Recipies:


Tips:

How to make media:
1.  Fill the beaker you're preparing the media in full to the final volume with water.  Then pour out half of the water and add your ingredients, then fill to the line.  This will insure that you do not excede your final volume in the end.
2.  Add the buffers
3.  Add major elements - in the order given.  Dissolve each one separately before adding the next ingredient.
4.  Add the trace elements last
