Whether or not a multichannel or electronic pipette could benefit your application depends on the following criteria: What vessels are you using? There are many ways to improve your pipetting efficiency, including the use of multichannel and/or electronic pipettes. In a high throughput setting, it is important to be as efficient as possible while keeping your pipetting processes reliable and consistent. Such tips require ‘hammering on’, which stretches the pipette tip rim. This can cause leaking or misaligned tips, or even cause the pipette tips to fall off the pipette completely! Choosing micropipettes which were designed together with the tips ensures secure connections and tips that do not leak or fall off. However, some pipette manufacturers have developed volume adjustment designs that prevent inadvertent volume changes while pipetting.ĭo your pipette tips ever loosen, leak or fall off? This is a common issue in laboratories, caused by the use of universal pipette tips. Volumes set on traditional manual pipettes can change while pipetting, due to unintentional plunger turns. Some electronic pipettes have useful features, such as setting a calibration reminder or saving the calibration history.Īre you wondering if your pipette is still working as intended? Follow these guidelines to perform a routine check. Your micropipettes should be easy to calibrate. Using a 300 µl pipette will give you better results, whereas using a 50 µl pipette would be ideal. For example, if you dispense 50 µl using a 5,000 µl pipette, you will get rather poor results. This is important because accuracy decreases when the set volume is close to the pipette’s minimum capacity. As a rule of thumb, always choose the smallest pipette capable of handling the required volume. Micropipettes are available in different volumes ranging from 0.2 µl to 5,000 µl. For maximum pipetting accuracy and precision, we advise you to look at the following criteria: Micropipette size:
