Cryostar has been New York’s leading laboratory equipment calibration service since 1989. And throughout the years, we’ve developed an expertise in the logistics of operating high-functioning labs.

Naturally, in any scientific industry, data is the principle reason for the work. Labs rely on intricate (and expensive) equipment to produce reliable readings. Many scientists believe that your science is only as good as the tools you use. And if your tools aren’t calibrated, all of your work is compromised.

Keeping your instruments in good condition is crucial. Even maintaining equipment that doesn’t produce data, like freezers and refrigerators, is vital to a lab. However, producing accurate data is of the utmost importance, and we rely on scientists in various fields (like medicine) to provide measurements that are reliable.

That’s where calibration comes in. Calibration is the process of evaluating and adjusting equipment in order to maximize precision and accuracy. And all lab personnel should be familiar with the process and importance of equipment calibration.

Below, you’ll find a clear guide on calibrating your instruments. We’ve also compiled useful information on why calibration is so critical to science of any kind.


Identify the Instruments to be Calibrated

Lab instruments that require regular calibration are the ones that weigh, count or measure. Mostly, this means pipettes, scales and balances, centrifuges or pH meters.

Essentially, the equipment that you rely on to produce data should be calibrated regularly.

So how do you know which instruments need to be calibrated, and when? Start by checking the recommendations from the manufacturer. Most will recommend calibration by a trained professional. Cryostar specializes in laboratory equipment calibration and can calibrate your equipment on-site or within our ISO 17025-accredited lab.

Always, always, always have your instruments calibrated right after any kind of mechanical mishap, shock or damage. Additionally, any abnormality should be reported right away. Even if there’s no immediate, visible signs of damage, your equipment could begin producing inaccurate results. And it might not happen right away. Calibration will not only refine your results, but also confirm whether or not the equipment needs repair.

Another way to know when to calibrate your instruments is to keep a documented schedule. By scheduling periodic calibration based on manufacturer recommendations, you’ll keep your equipment in the best possible shape. You’ll also be keeping your lab as cost-efficient as possible.


Schedule & Plan Your Calibration

Laboratories have a few ways of calibrating their instruments. Essentially, it all depends on the equipment and the manufacturer. It’s critical to understand your machinery. And, reading the instruction manual in full is the best way to understand it.

Cryostar provides calibration services on a regular basis to several labs in the New York/Long Island area. We use test and measurement equipment certified to NIST traceable standards (more on that shortly!) Additionally, we provide complete documentation for each instrument calibrated; and our calibration methods and reports meet FDA and ISO 9000 requirements.


Traceability & Its Importance

Traceability is a common term when researching equipment calibration. In fact, it’s vitally important.

NIST (National Institute of Standards and Technology) Traceable Calibration is a program that verifies a lab or equipment provider is fully certified to calibrate equipment to their standards. Basically, NIST ensures that the products provided by manufacturers meet their equipment standards.

NIST traceability is critical to quality assurance. Essentially, traceability is defined by NIST as “property of the result of a measurement or the value of a standard whereby it can be related to stated references, usually national or international standards, through an unbroken chain of comparisons all having stated uncertainties.”

All of your equipment should be calibrated to NIST traceability standards. Whether it’s your lab’s personnel or a professional calibration service like Cryostar, ensuring they’re familiar with traceability is critical to proper calibration.


The Benefits of Regular Equipment Calibration

All measuring equipment begins to degrade over time. Sometimes it’s from production defects, but mostly it’s average wear and tear. And when it starts to degrade, the accuracy of the measurements begins to decline.

The bottom line is: you want your data to be reliable and accurate. Calibrated equipment will help you to produce quality, traceable results. And ultimately, regular calibration will save you a lot of time, money and stress.

Instruments that aren’t calibrated on a regular basis will lead to unnecessary expenses in the future. They will continue to produce unreliable, inaccurate readings for a very long period of time. And they can be abruptly damaged beyond repair. To avoid providing clients with incorrect information or replacement costs, simply calibrate your equipment.



If your lab relies on producing data, calibration is a must. It will save you time, money, stress and even help to keep your lab eco-friendly.

Whether it’s through equipment rental, repairs or calibration, we’ve maintained a steadfast respect for the scientific community. And we understand exactly how many factors must be refined in order to keep your lab running efficiently.
