Best Maintenance Practices for Long-Lasting Variable Volume Micropipettes
In any high-performance laboratory, Variable Volume Micropipettes are indispensable workhorses. Because these precision instruments are used continuously throughout the day, they are constantly exposed to mechanical wear, chemical vapors, and biological samples. Without proper care, even the most robust pipette can suffer from diminished accuracy, tracking errors, or premature failure.
To protect your data and extend the lifespan of your liquid handling equipment, implement these essential maintenance practices.
1. Daily Cleaning and Decontamination
At the end of every working day, wipe down the exterior of your pipettes with a mild laboratory disinfectant, such as 70% isopropyl alcohol. For labs working with hazardous materials, nucleic acids, or infectious agents, regular autoclaving or chemical decontamination of the lower shaft assembly is critical to prevent cross-contamination and internal corrosion.
2. Proper Storage is Key
Never leave a pipette lying flat on a laboratory bench, as this allows residual liquids or corrosive vapors to seep up into the internal piston mechanism. Always store your instruments vertically on a dedicated carousel or wall stand. Furthermore, when your Variable Volume Micropipettes are not in use, turn the volume dial to its maximum capacity. This releases the tension on the internal spring, preventing mechanical fatigue over time.
3. Check for Leaks Regularly
A compromised seal is a leading cause of volume inaccuracies. Perform a quick, daily leak test: aspirate water at the pipette's maximum volume, hold it vertically for 15 seconds, and watch for any drops forming at the tip. If a leak is present, it usually indicates that the internal O-ring or shaft seal needs lubrication or replacement.
