On the other hand, you could dilute the stock solution 10 times and pipette 50 µL of the solution. I used the reverse pipetting technique and found that that is the most accurate technique for this. On the other hand, if you diluted the stock solution 10 times and pipetted 50 microlitres, this would be much more accurate, giving you much tighter error bars. Human body heat can also be transferred from the user to the pipette if handled for too long, also causing volume variation.
That is, when you arrive at 157 microliter coming from 200 you will get a somewhat larger volume than coming from 100 microliters. The system returned: (22) Invalid argument The remote host or network may be down. Test Your Accuracy Check the accuracy of your pipetting technique by dispensing 100 µL onto a fine balance.
