Pipettes are indispensable tools in laboratories, research facilities, and medical settings, used to accurately measure and transfer liquids. To ensure consistent and reliable results, it's crucial to properly maintain and care for your pipettes. In this article, we'll provide essential tips for pipette maintenance to help prolong their lifespan and maintain accuracy.
1. Regular Cleaning
Clean your pipettes regularly to prevent cross-contamination between samples. Use a mild detergent and distilled water to clean the external surfaces. For the internal components, use a lint-free cloth dampened with isopropanol or ethanol to wipe down the pipette shaft and piston. Make sure to follow the manufacturer's guidelines for cleaning to avoid damaging delicate components.
2. Calibrations and Verification
Schedule regular calibrations and verifications of your pipettes to ensure accurate measurements. Calibration checks should be performed by trained professionals using calibrated equipment. Verification using gravimetric or photometric methods can help confirm the accuracy of your pipettes when dispensing specific volumes.
3. Proper Handling
Handle pipettes with care to avoid mechanical damage. Always use the appropriate force when operating the plunger to prevent excessive wear on internal components. Avoid dropping pipettes or subjecting them to impact, as this can lead to misalignment and inaccurate measurements.
4. Tip Selection and Replacement
Choose pipette tips that are compatible with your specific pipette model. Use high-quality, certified tips to ensure accurate and consistent results. Replace tips between each sample to prevent cross-contamination. Make sure the tips are securely attached to the pipette to prevent leakage or imprecise measurements.
5. Storage and Handling
Store your pipettes in a clean and dry environment to prevent dust and contaminants from affecting their performance. Use pipette stands to keep them upright and avoid contact with surfaces. If your pipettes are not in use for an extended period, store them with the plunger released to relieve stress on internal components.
Conclusion
Proper maintenance of pipettes is essential for obtaining accurate and consistent results in laboratory and medical settings. By following these tips and adhering to manufacturer guidelines, you can ensure that your pipettes remain in optimal condition, extend their lifespan, and contribute to the reliability of your research and analyses.

Product introduction:
HAST (Highly Accelerated Stress Test) is a type of test that is used to evaluate the reliability of electronic components and other materials under high temperatures and humidity. A HAST test chamber is a device that provides controlled conditions of high temperature and humidity to simulate the effects of aging and degradation on materials over a shorter period of time than would occur in normal use.
During testing, the sample to be evaluated is placed in the HAST chamber, which is then heated to a high temperature and subjected to a high-pressure steam environment. The temperature and humidity levels are carefully controlled to ensure that the sample is subjected to the appropriate conditions.
The purpose of the HAST test is to identify any weaknesses or defects in the material that may cause it to fail prematurely in real-world use. By exposing the sample to accelerated aging conditions, engineers can evaluate the long-term reliability of the material and make any necessary improvements to its design.
HAST test chambers are commonly used in the development and testing of electronic components, such as integrated circuits, printed circuit boards, and semiconductor devices. They are also used in other industries where materials must be able to withstand harsh environmental conditions, such as the aerospace, automotive, and medical device industries.
