You cannot use a 2-20 µl micropipette to pipet 200 µl O b. To expel all the liquid from the tip, you have to press the eject button O c. To draw up solution, press and hold the plunger at the first stop before entering the solution O d. Micropipettes always require the use of a disposable plastic tip O e. While pipetting, micropipettes should always be held as straight as possibleIndicate whether you think that the number of cfu/ ml calculated would be too high or too low if you make this mistake. 1.You intend to add 9ml of broth (water) to each tube and 1 ml of culture. Instead, you add 5 ml of broth to each tube and 5 ml of culture to the first tube. Then, you make a serial dilution of 1 ml into and from each tube as described. 2. You prepare 9 ml of broth (water) in each tube. You add 1ml of culture of every tube. 3.You add 9 ml of broth (water) to each tube. You add 1 ml of culture to the first tube and mix. You get distracted, and transfer 1ml of the dilutant (mixture of culture and broth) to the third tube instead of the second. You perform the rest of the series as described.What is the hazard of the spattering tendency in heating a wire loop with specimens over a flame? (Answer in not more than 2 sentences)
- On the graph that relates absorbance to flavin concentration, draw a horizontal line that starts at the point on the y-axis that corresponds to the absorbance of your unknown sample and ends at the curve you drew through your data points . Next draw a vertical line that starts at the point where the horizontal line intersected the curve and ends at the x-axis. The point where this vertical line intersects the x-axis corresponds to the concentration of flavin in your unknown sample. What was the letter on the tube with your unknown sample?
