Published: ISO 20836:2021 - temperature performance testing of thermal cyclers

Date: 09-Jan-2023

ISO 20836 specifies requirements for the installation, maintenance, temperature calibration and temperature performance testing of standard thermal cyclers and real-time thermal cyclers.
It enables laboratories to determine if a thermal cycler is suitable for intended use and if it meets the requirements as set by the laboratory.
The standard has been established for laboratories performing polymerase chain reactions (PCR) in for example the food, environmental, human health, animal health and forensic testing domains.
The CYCLERtest thermal cycler calibration method meets the ISO 20836.

On the 14th of February 2022 the ISO 20836 was introduced by NEN via a webinar (in dutch).

Slides of the presentation are available in dutch and english.

Coronavirus and RT-PCR equipment

Date: 03-Feb-2020

The latest coronavirus 2019-nCoV is diagnosed with RT-PCR which detects the amount of viral RNA in a patient’s blood, serum and/or sputum. It goes without saying that the used (q)PCR equipment has to function properly. To assure proper operation (q)PCR cyclers need to be calibrated regularly according to international standards.

Even though the metrologically traceable temperature calibration is an ISO required norm for medical and test labs, not all of them adhere to the rules. But as a potential patient you don’t want to spend two weeks in isolation if you’re not sick and you don’t want to be send home when you’re seriously ill. We therefore advocate that all labs calibrate conform the norm and auditors assess accordingly. Better be safe than sorry.

Temperature calibration guide for (q)PCR thermocyclers

Date: 02-Dec-2019

Most (q)PCR optimizations are performed on DNA, primers and template variables. Yet, very little attention is paid to the effect plastics and thermocyclers have on the (q)PCR result. They are incorrectly considered to be constants in the PCR process.
In this guide we illustrate different types of thermocycler variabilities and the impact they have on the (q)PCR results. We also give practical solutions on how to eliminate or control these variabilities.

You can easily use the data from the calibration certificates in practice. We give examples on how to align and program thermocyclers to mimic each other. You also learn how to use calibration results for validation purposes.

Supply chain (e)quality

Date: 14-Nov-2019

We all want to enjoy a wonderful meal and drink a glass of tap water to quench our thirst without having to worry about safety. The same counts for the diagnosis we receive from a laboratory test.

Therefore our commitment to quality is not restricted to our products and services. The highest standards are achieved when the entire supply chain focuses on quality, from manufacturers of thermal cyclers through distributors to end-users. End-users play the most important roll to ensure reliable (q)PCR results. After all: any lack of attention to reliability can have negative implications.

All parties involved comply with certain regulations to combat problems, concentrating on preventing instead of curing them. By doing so, the highest quality level is met.

  • Distributors control the quality of thermal cyclers with MTAS calibration tools to meet specifications
  • End-users control the quality of their thermal cyclers annually - either with Driftcon calibration tools or with accredited on-site calibration service with MTAS system – to fully understand the performance of their cycler
  • Calibration tools are calibrated in an accredited calibration laboratory to make sure that they perform according to international standards
  • (q)PCR consumables are manufactured according to strict specifications for reproducible and reliable results. The characteristics:
    * Composition is always identical so consistent results
    * Low binding: all DNA is available for a reaction
    * (q)PCR is possible in volumes as low as 5µl
    * Pyrogyn, DNA(se) & RNA(se) free

We are extremely proud to have achieved this level of quality with our cooperation partners and are committed to further expand this method.
Better be safe than sorry!


Date: 24-Oct-2019

In accordance with the ISO 15189 standard for medical laboratories and ISO 17025 standard for testing laboratories any measurement equipment used for testing that has significant influence on the accuracy or validity of the test result needs to be calibrated to (inter)national standards (requirement of ISO 15189: 2012 and requirement 6.4.5 & 6.4.6 of ISO 17025: 2017).

CYCLERtest offers a unique on-site calibration service.

The advantages:
•You meet the ISO 15189 or ISO 17205 quality requirements
•The temperature calibration is traceable to international quality standards
•You support reliable and reproducible (q)PCR results
•The service applies to all models of all brands of thermocyclers and dry heating block incubators
•Your equipment downtime is less than 40 minutes.

The only qualified calibration laboratory
Because we are independent of every thermal cycler manufacturer, CYCLERtest is the only qualified calibration laboratory in the world that can calibrate real-time PCR equipment under ISO 17025.
Thermocycler manufacturers are not able to perform metrologically traceable calibrations under ISO 17025, partly because they are not independent.

In-tube or in-well thermal cycler calibration method

Date: 03-Oct-2019

During the 19th International Metrology Congress in Paris, CYCLERtest presented a comparison between an in-tube- and in-well thermal cycler calibration method. The study - performed with BIOplastics’ tubes - showed that it is feasible to develop an in-tube method with a low measurement uncertainty. However, due to the large impact of the tube-to-well fit on the measurement uncertainty and the large variability between tubes, it is not practical to use in-tube methods for metrology purposes. An in-well thermal cycler calibration method is therefore the preferred option. Read all about the research in the abstract Comparison of temperature dynamics of various thermal cycler methods.

CYCLERtest gained US Patent for Optical Calibration of qPCR cyclers

Date: 03-Feb-2019

CYCLERtest is proud to announce that its patent for the optical calibration of qPCR cyclers is now also granted in the USA. The US patent complements similar patents held by CYCLERtest in Europe and Japan.

The traceable Optical Calibration tool and service is ‘a major breakthrough for molecular diagnostics and life sciences’ according to CEO Tom Hendrikx. ‘With this advanced technique variables in qPCR are monitored, minimized and become controllable. This gives laboratories a better understanding of the qPCR process and enables them to expand its capabilities. This superior method with new developed hardware supersedes the, so far used, non traceable techniques as biological testing, crystal color changes and others!’

The innovative technique is based on the traceable calibration of temperature, optical detection and light of (q) PCR cyclers (excitation and emission). A truly unique method since these components are not only detected and generated separately but also in relationship to each other. By doing so, the performance of the real-time thermal cycler is monitored and calibrated like never before.

About CYCLERtest
CYCLERtest - a pioneer and global leader in ISO 17025 accredited (q)PCR cycler calibrations - is headquartered in The Netherlands and represented by qualified distributors worldwide. Its highly accurate calibration tools and services enable laboratories to monitor the performance of their thermo cyclers according to global quality requirements.

Normalizing SOPs

Date: 24-Jul-2009

Many laboratories have SOP (Standard Operation Procedures) in place. Incorporation of new components in SOP’s are generally labor and time consuming. In the (q)PCR process, variables as cyclers, plastic disposables, kit components and work procedures are typically described and incorporated in SOP’s. Often different SOP’s in place for one application are used on several (different) cyclers. BIOplastics and CYCLERtest® have formulated a strategy which enables exclusion of the cycler as well as the used disposable variable. This strategy actually provides users the ability to normalyze their SOP. You can download the PDF in our download section
