So, now we super mario 3d land guide finally have all the pieces of serial dilution assembled: Dilute Calculate dilution factor Plate Repeat To make things easier, the standard operating procedure is to go by factors of 10, and ccie wireless lab workbook to do about 5 or 6 plates altogether.
In the applet below, you can practice the whole process of serial dilution from beginning to end.
