Pipettes play important roles in laboratories throughout the world. In order to replicate test results and arrive at accurate diagnoses and discoveries, researchers create and observe very specific biological processes. These processes often depend on the repeatability of exact ratios and precise measurements. Pipettes must deliver both as they contain, transfer, and measure fluids in a laboratory setting.
Of course, pipettes and the mechanical parts within them, such as plungers and pistons, will undergo slight changes over time. Cross contamination, temperature or humidity changes, human error, and everyday wear and tear will compromise a pipette's accuracy and function. That's why it's so important to clean your instruments thoroughly and seek accurate and effective calibration services that operate according to the science of liquid measurement.
Your calibration service must follow strict regulations and methodology standards set by ISO, the International Organization for Standardization. ...
We recently discussed some common mistakes scientists make when choosing a calibration service provider for their pipettes. As we learned, the choice of a calibration service provider is often made quickly, and without much thought to quality priorities. So how do you differentiate a high quality calibration service provider from a substandard one? Here are some tips.
As is the case with many decisions, when the complexity of the choice is not well understood, people make their choices based on convenience and price. Though both of these factors are important when choosing a calibration service, a more important factor is how effective the service provider is. Here are factors to not use when making you selection.
The EON S is the last pipette you’ll ever buy because, for as long as you own and calibrate it with TTE every 6 months (as most labs do), you will enjoy unlimited, free parts, repairs and replacement, as well as easy budgeting, with the only future expenses being the 6 month calibrations.Continue reading for details...

Many users of pipettes do not realize that distinct balances are required to calibrate different pipettes. If you are currently using an onsite pipette calibration provider, you should take note of the measurement equipment your provider carries into your lab. Depending upon the equipment used, you may be settling for a great deal of unnecessary measurement uncertainty. Most of the time, on-site companies are limited to the use of improper balances to calibrate your pipettes. Unfortunately, many calibration service providers attempt to use a one-size-fits-all approach when calibrating pipettes, and the quality of calibration suffers as a consequence.
Our top news stories include the story of a science teacher who is a lab hero for her school, a robot pill that delivers medicine using tiny sugar needles, and the development of limbs grown in the lab. Each week we post interesting news and information relating to metrology, pipetting, research, and more which you can find on our Industry News page.
EZCal comes with a number of free benefits, including free shipping and free 24 -hour turnaround time. One of the "hidden" benefits of the program? One particularly compelling reason to use EZCal is the reduced liability accompanying our off-site, laboratory calibration.
Based on the impact of the testing environment on the balances used to calibrate pipettes, it is important that calibration services minimize those environmental effects to ensure the reliability of results determined by the balances. One strategy to reduce environmental impact on pipette calibration is to have pipettes calibrated off-site. Those who provide pipette calibration services off-site are able to control all the environmental factors that can adversely impact pipette volume and the integrity of calibration.
