1. Benchtop EPR: Making Teaching Labs Smarter and Simpler

Not every lab needs a full-scale floor-standing spectrometer. For teaching and routine experiments, benchtop EPR systems are rapidly becoming the default. Their appeal lies in ease of use, portability, and strong baseline performance.

At the Universiteit Utrecht, for instance, a CIQTEK benchtop EPR spectrometer EPR200M was recently installed. The system is compact enough to fit on a standard bench and comes with intuitive software that new users can operate within an hour. Professors there reported reliable detection of short-lived radicals in lab experiments, without the learning curve typically associated with EPR.

These compact EPR spectrometers strike the perfect balance for chemistry and materials science teaching labs, making high-quality EPR spectroscopy more accessible than ever.

 

2. CW EPR with Variable Temperature: A Must for Research Flexibility

For labs focusing on spin dynamics, catalytic mechanisms, or materials, cryogenic measurements are essential. Many researchers in Germany and France are now demanding CW EPR spectrometers with reliable variable temperature (VT) capabilities, preferably with plug-and-play usability.

CIQTEK’s CW EPR system, designed for X-band EPR spectroscopy, includes built-in support for nitrogen and helium-based VT experiments using cryostats. A recent installation at a German materials science institute confirmed its smooth temperature cycling, with stable signals even at temperatures as low as 10 K. The system eliminates the need for complex manual tuning, making it easier for academic groups with rotating users or tight schedules.

If you need low-temperature EPR spectroscopy without needing a cryogenics specialist on your team, this kind of integration makes all the difference.

3. Balancing Budget and Ambition: Affordable EPR Spectrometers for Universities

Let’s face it: even the best labs face budget constraints. But cost shouldn’t mean compromise. Universities across the UK, especially those outside of the golden triangle, are actively seeking affordable EPR instruments that deliver serious scientific value.

In one standout case, a France-based spin chemistry group was evaluating options for a pulse EPR system. Traditional vendors quoted high prices and long delivery times. CIQTEK offered a complete Pulse EPR solution with echo-detected and relaxation measurements, along with full software automation, at significantly lower cost.

After on-site testing, the team praised the signal-to-noise ratio, the modern interface, and the rapid support during commissioning. The system is now in daily use, generating data for upcoming publications.

 

4. Support That Actually Supports You

Instrument specs are important, but for many labs, what happens after delivery is what defines long-term satisfaction. Delays in support or a lack of local expertise are still common pain points.

In 2024, a lab in Romania reported slow response times from their legacy vendor. After switching to a CIQTEK EPR system, the team noted faster communication, efficient remote diagnostics, and access to EU-based demo centers. This helped them reduce downtime during the semester, critical for meeting academic schedules and student training goals.
