Accuracy is of paramount importance in scientific research and lab work. Accuracy in your lab begins with having correctly calibrated pipettes. Different pipette calibration plans are available to meet the varied needs of different labs. It is important to know what level of pipette calibration your lab requires to pick the correct plan to meet your needs. All labs and scientists require accuracy from their pipettes, but some require more stringent regulatory compliance standards than others. Most pipette calibration service providers offer a number of different pipette calibration levels, as well as offering pipette repair.
Electronic pipettes offer greater accuracy and precision, reduce the risk of costly human error, provide greater efficiency and features, and reduce the risk of repetitive strain injury (RSI) when compared to manual pipettes. However, electronic pipette calibration is also necessary. Electronic pipettes calibrate better than manual pipettes resulting in fewer calibration failures. In general, electronic pipettes are factory calibrated using an analytical balance and distilled water in accordance with the ISO standards. Therefore, a new electronic pipette does not usually need to be calibrated. However, all pipettes require calibration at regular intervals to remain accurate and precise. The amount of time you allow between your electronic pipette calibration events depends on the stringency of the regulations and requirements of your lab.
Electronic pipette calibration, for most electronic pipettes, involves 3-point calibration for optimal accuracy at all volumes, just like manual pipettes. This is usually the default calibration setting. However, most electronic pipettes also offer 1- and 2-point electronic pipette calibration options for less stringent applications. Most electronic pipettes will have a calibration menu which will take you, step-wise, through the electronic pipette calibration process for your unit. They will also provide you will a last calibration date and due calibration date based on your required calibration intervals. Electronic pipettes make the whole process easy and straightforward for your convenience and improved accuracy of your science.
