How accurate are Eppendorf pipettes?
How accurate are Eppendorf pipettes?
At 1 000 m above sea level, the volume error of a 100 μL pipette is about –0.3%. When using special tips, that is, tips that significantly differ from standard tips in their geometry, changing the adjustment can improve the dispensing accuracy (systematic error).
How often should Eppendorf pipettes be calibrated?
The renewal of conformity is recommended at least once a year. What is a renewal of conformity? The calibration / renewal of conformity consists of a pipette maintenance and an As-Left calibration strictly adhering to ISO 8655 criteria, ensuring that the pipette meets conformity to ISO 8655 requirements.
What is Eppendorf micropipette?
Eppendorf pipettes are a common laboratory tool used to measure and transport liquid. Due to the cost of these useful instruments, you’ll have to take care to preserve their condition. Pipettes also have different colored tips which represent different dosages.
Where are Eppendorf pipettes made?
Germany

Eppendorf products are used in academic and industrial research laboratories, e.g. in companies in the pharmaceutical, biotech, chemical and food industries.
Why can you not manual add the tip to the micropipette with your hands?
Avoid handling pipette tips or reservoirs with bare hands. Body heat transferred during handling disturbs temperature equilibrium, which leads to variations in delivered volume. Before aspirating, immerse the tip adequately below the meniscus.
Why is the accuracy of micropipettes important?
The accuracy of a micropipette decreases somewhat when micropipettes are set to deliver volumes close to the lowest values in their range. Precision provides information about reproducibility, without any reference to a standard. Precision reflects random errors that can never be entirely eliminated from a procedure.
How often should I calibrate my pipettes?
every 3 to 6 months
The Clinical and Laboratory Standards Institute (CSLI) recommends that pipettes (single and multi-channel) and automated liquid handlers be calibrated every 3 to 6 months. A minimum of two volumes must be tested (nominal and lowest setting) with ten replicates at each volume.
How do you maintain a micropipette?
Treat micropipettes very gently as they are precision instruments. Keep upright when in use to prevent liquids running inside the shaft of the pipette. Do not leave pipettes lying on the workbench where they can be knocked off and damaged. Before use, make sure the volume has been correctly set.
