Is the convenience of on-site calibration really worth it? While some on-site services boast about their speed and their ability to produce immediate results, finding a ‘quick and convenient’ calibration service can sacrifice your pipette’s accuracy. Cutting corners with a calibration service that does not have the correct equipment will end up costing your lab more money, time, and effort. Can your lab really afford to re-calibrate all of your instruments, re-purchase reagents, and repeat all the hours spent on the experiment? Finding a quality off-site calibration service, such as Pipette.com/Accutek Lab, will guarantee reliable calibration of your liquid handling instruments.
Are They Qualified?
Most calibration service companies state they comply under an ISO 9001:2008 standard. However, anyone can claim to be a metrology specialist simply because they have have years of experience. Here at pipette.com, we combine of years of experience and a more rigorous certification process to deliver a more precise calibration and better results. Pipette.com is ISO 17025:2005 accredited, which “specifies the general requirement for the competence to carry out tests and/or calibrations, including sampling. It covers testing and calibration performed using standard methods, non-standard methods, and laboratory-developed methods.” ISO 17025:2005 and ISO 8655:2002, which are in compliance with the piston-operated volumetric standards, lead to a skilled and reliable calibration service. In addition, an FDA registered facility will solidify the qualification of a calibration service that can and will deliver superior results.
What is Needed to Accurately Calibrate?
Proper calibration takes adequate accreditation and National Institute of Standards and Technology (NIST) traceable equipment. Two of the most obvious piece of equipment that on-site calibration service lacks most of the time are stone tables and ultra-micro balances. An important question to ask on-site calibration personnel is whether they use an ultra micro balance? If they’re answer is “no, we use an analytical balance,” then that automatically tells you that they are not using adequate equipment to properly calibrate your micropipettes. An ultra micro balance is able to precisely calibrate 20 uL (or less) pipettes while analytical balance cannot. Analytical balances are ideal for milligrams and ultra micro balances are perfect for micrograms. Stone tables are needed to reduce vibration to measure at a precise rate. If an on-site calibration service is constantly moving their balance, they may risk shifting the balances’ calibration and pipettes’ accuracy. An ultra micro balance needs 24 hours to acclimate to its environment to provide accurate results. If a balance is moved before being used for calibration it will not provide accurate results. Other calibration equipment that is needed for precise calibration is:
- A Calibration Weight
- Up-to-date Calibration Software
- Controlled Environment Parameter
- Temperature and humidity
- Ultra Micro and Analytical Balances with Evaporation Trap
- Distilled Water
Each of these components leads to a properly calibrated pipette. While on-site calibration services boast about their ‘speed and convenience,’ their quick and possible superficial manner of calibration is not the most efficient or correct way.
Fortunately, an off-site service will take time to disassemble the pipette and utilize the appropriate spare parts to improve the pipette, as well as perform legitimate tests with NIST certified and correct equipment. Furthermore, off-site service will calibrate under a controlled environment as exact conditions are mandatory to calibrate properly. They will examine the seals, make adjustment to worn out parts, and re-grease parts that need it. Essentially, off-site calibration service will bring new life to your pipette and prolong its usability.
Off-Site Delivers Precise Results
Calibration is designed to identify the faults of a pipette as well as solve them accordingly and accurately. Correct maintenance of your pipette is not always achievable by on-site calibration – it is not a dependable service. A full-service program is needed to achieve maximum and legitimate results. Though on-site calibration service seems ideal because it sounds inexpensive and easy, the results can be sloppy and unreliable. The precision and dependability of your pipette matters more than the extra dollars you might save on the on-site calibration service.
For a dependable pipette calibration service, a pipette has to be clean, accurate, precise, and have a calibration sticker. Furthermore, when you receive your pipette(s), you must have access to reports and calibration history. These are basic necessities that are essential to ensure you save on reagents, samples, and time by having accuracy in your results. Pipette.com/Accutek Lab is able to provide all these necessary features when calibrating your pipettes.
