Web3 sep. 2013 · But in science, we don’t yet have all the answers. Sometimes the best we can do is to develop theories, so it’s important to be comfortable with complicated answers. During a lab, don’t be overly focused on getting the “expected” results; in science, any experiment that yields data is a viable experiment. WebStandard (or forward) mode pipetting yields better accuracy and precision than reverse mode for all but viscous or volatile liquids. Reverse mode often results in over-delivery. Hence, it’s recommended to evaluate the effect of possible over-delivery in the experiment and make adjustments if needed.
