DILUTIONS AND STANDARDS

1/4 x 2/4 or 1/4 x 1/2 = 1/8 in 2nd tube . By transferring 2 mL of dilution from one tube to a second tube containing 2 mL of saline, and continuing to do so, this is actually making a 1:2 serial dilution. PROBLEMS: 1. You made a 1:2 dilution of serum. Then you added 2 mL of that to 4 mL of water. ................
