- Using a P-1000 micropipette, you transfer 800 microliter of ddH2O to a beaker and measure its weight. It turns out to be only 780 milligram; what is the percent error of this micropipette?How would you make two-fold serial dilutions such that the last tube is a 1:32 dilution of the original, concentrated material? Assume that you need to have at least 500 µl of each dilution, and you should be able to perform the dilutions in microfuge tubes with a maximum capacity of 1.5 ml.DILUTION COLONY COUNT CFU/mL 1:106 155000 1:107 15500 1:108 1550 1:109 155 Given these values how would I fill in the rest of this serial dilution table? Also, what would be a 1:1 CFU/mL value based on this table?

Be sure to show your work and include the volume of 0.02 M phosphate buffer required to reach a final volume of 1 mL. From a 2,000 μg/mL BSA stock, create 1 mL of each of the following stock solutions in 0.02 M phosphate buffer using individual microcentrifuge tubes: 50 μg/mL, 250 μg/mL, 500 μg/mL, 1,000 μg/mL, 1,250 μg/mL, 1,500 μg/mL. Be sure to properly label all the microcentrifuge tubes before creating the standards.The original concentration in a sample of kombucha is 2.79 x 10^6 CFU/ml.
