Antibiotics 2013 kdorfman Mon, 01/28/2013 - 19:48(weight indicates how much should be on one disk.)
Calculate concentration from volume needed per disk (25 uL)
Make 35 mL of each (because the filter syringe only holds that much)
See recipes in stock solutions.
Make 35 mL each, make 48 0.7 mL aliquots
