- Which is more accurate, a transfer pipet or a measuring pipet? How much is the uncertainty in microliters when you deliver (a) 10 !L or (b) 100 !L from a 100- !L adjustable micropipet?The volume of the solution that can be measured with 5-10 microliter pipette and 2-20 microliter pipette is 0.005-0.01 mL and 0.002 mL-0.02 mL. The volume of the solution that can be measured with 20-200 microliter is 0.02-0.2 mL. The volume 1 mL of solution is measured with 100-100 microliter which has capacity of 0.1 mL to 1 mL. What would the display read for 0.10 mL, 0.20mL, 0.40mL, 0.60 mL, 1.0 mL read when using the micropipettes mentioned aboveIf I was in a rush and only let my TLC plate run 1 cm. Am I going to encounter anyissues? If so, what?
