All these influence Pipetting outcomes. By way of example, If your idea is not really straight this alone might lead to a 10% error in Pipetting accuracy (ISO 8655-2). Additionally, In case the suggestion orifice is just not correctly centered, the dispensing on the liquid may very well be influenced drastically. If high quality quality pure polypropylene is just not used or even the mold and processing are Lower than the best criteria, Component of the liquid stays Within the tip as a droplet, which causes an error from the Pipetting consequence.
