Als de nauwkeurigheid en herleidbaarheid van onderzoeksresultaten van belang zijn, is een programma voor kalibratie en onderhoud de zekerste manier om op hoog niveau pipetterenprestaties te handhaven. Regelmatig onderhoud-toegesneden op uw specifieke behoeften en applicatie-kan out-of-tolernace fouten verminderen, verlengen de levensduur van de pipet en bespaart tijd en geld door het elimineren van extra werk.
Like any precision instrument, pipettes require regular servicing in order to maintain peak performance. They are comprised of a variety of mechanical parts that, like all things mechanical, wear out over time:
- In the case of pipettes, it is the seals that are most prone to wear. They usually perform for up to a year or more without leaking depending on pipette usage.
- Over time, shaft ends can get damaged especially when a high force or ‘banging’ occurs when mounting tips.
- Piston surfaces can deteriorate from shiny and clean to pitted especially when using aggressive or corrosive samples, leading to premature seal failure and pipette inaccuracy.
Leakage often starts gradually and may not be discovered until well after the accuracy and integrity of your research is compromised. However, a lab’s internal pipette failure rate can be significantly reduced via a program for regular maintenance and calibration.
Based on our extensive experience and under normal use, seals should be replaced at least once a year and shafts every year or so while pistons will provide good performance for at least several years before needing replacement.
METTLER TOLEDO offers a variety of calibration and preventive maintenance program options to suit all budgets and applications.
