All pipettes require regular maintenance to ensure reliable results and maximum equipment life. Many users in the process of using the pipette will find that sometimes the pipette becomes unusable or the pipette is broken. In reality, however, many pipettes are "not easy to use" because the pipette is broken, but the pipette needs maintenance.
Do you have the following conditions when using the pipette?
1. The feel of pressing the operation button becomes unsmooth and feels blocked;
2. The operation button cannot be restored to its original position after being pressed;
3. Lift the pipette after pipetting, and the liquid will continue to leak slowly/slowly (even if it absorbs water, this is normal for volatile liquids)
4. When the operation button is released while aspirating, no liquid is sucked into the tip at all...
In a similar situation, do you think the pipette is broken? This is indeed possible, but more than 90% of this situation is due to lack of timely maintenance.
If the pipette does not have regular maintenance that will affect the user's use, then no regular calibration will directly affect the reliability of each operation, and such effects are imperceptible and not necessarily noticeable. Generally speaking, if the performance of the pipette itself is not problematic, the accuracy of the pipette will be affected by the time, frequency of use and personal usage habits. If it can be calibrated periodically, it can be guaranteed to perform better during the interval between calibrations. The pipette manufacturer recommends that the pipette be calibrated at a frequency no less than once a year.
It can be seen that it is extremely important to regularly calibrate and maintain the pipette!
To do pipette cleaning yourself, first make sure it is easy to remove, and the fewer parts that can be removed, the better. The most easily cleanable pipettes on the market have only three parts to be removed, and no tools are available for disassembly. At the same time, when selecting pipettes, it is important to consider the factors of after-sales. Manufacturers should have professional maintenance and calibration capabilities, and understand the quality, cost and speed of their services. If you are permitted by law and wish to complete the calibration work, please refer to the requirements of ISO8655.
