Calibration involves different aspects, and this is illustrated by the fact that the term itself does not have a standard definition. It could mean measuring the performance of an instrument and report it in some way, or measure its performance and compare the results with its specifications. Cost is probably the major factor that people consider when looking for calibration services. However, most technicians considered cheaper provide incomplete services that lead to additional cost. Below are four tips to help you find a reliable service provider.
1. Determine the standards used by the service provider
ISO 8655 specified to POVA (piston operated volumetric apparatus) gives a detailed prescription about calibration of pipette instruments. A service provider practicing procedures according to ISO 8655 standards have more reliable pipette instruments compared to a provider using the ISO 17025 standards. Most of the providers apply the ISO 17025, which is a broad calibration industry.
2. Check the number of balances the service provider uses for the calibration service
Distinct balances are useful when calibrating pipettes with different volumes that have adequate resolution. For those who make use of the same balance for pipettes that differ in sizes, the calibration results would not be quite impressive. This is similar to people who weigh themselves on a truck scale. If you discover a service provider using one balance to all your pipettes, then don’t consider them because they would not be accurate.
3. Find out whether a calibration facility is under control or on-site
Though on-site services seem convenient, it compromises the quality of the calibration service. It’s not a convenient choice. Calibration companies using their facilities have high-quality equipment that delivers reliable results. Proper calibration has temperature and vibration strictly controlled, a guarantee to reduced measurement uncertainties. For those of you interested, there is more information available at Calibration Service.
4. Find out the calibration procedure the service provider applies
Some of the service providers use methodologies that are not approved, such as quick onsite service. The methodology is not convenient. The service provider has to conduct the preventive procedure, which involves cleaning and opening the instruments to guarantee a reliable performance. It is useful just as servicing a car periodically is to maintain it. If the provider skips this step, then it shows that they are not providing reliable service.
Other factors to consider include cost and inconveniences. All in all, you should select a reputable calibrating company and set up a periodic plan for your instrument. It is only through the service that users would ensure high-quality instrumentation.
