The world's only solution to quickly increase the sensitivity of your X-Band Spectrometer

With eSPECT+ Expansion module the new era of EPR Spectroscopy is within your reach


Improve EPR signal form this

To that

With the eSPECT+ Expansion module, the new era of EPR Spectroscopy is within your reach!


Receive Better Results

With the eSPECT+ you can get 10, 100 or even 1000 times better S/N Ratio, which will allow you to acquire weak signals and examine lossy samples. You will also improve the results for the standard solid samples


Save Time

You can decrease the time of the signal accumulation to receive even better results than before


Wider Range Of Measurements

With the multiharmonic analyser you can perform research on lossy samples and with high water concentrations of water, therefore you will be able to safely examine living objects.


Quick Solution

In most cases, we are able to plug the eSPECT+ into your spectrometer in less than an hour, with the short training you can start your research the same day

improved S/N ratio

perfect solution for detecting weak signals

increased sensitivity

Compatible with Bruker Systems!

Our multiharmonic analyzer provides an excellent opportunity to upgrade your current EPR quickly and easily, specifically designed to seamlessly integrate with the Bruker System.

If you’re a Bruker user, you can now leverage Novilet’s innovative multiharmonic analyzer with your existing spectrometer. For more details, please get in touch with a Bruker local representative.

Take a look and discover the full potential of eSPECT+

Press the button and see how you can improve your S/N ratio !

You can compare the primary signal from the spectrometer to the signal acquired through multiharmonic expansion module.

The parameters of the experiment:

  • the nitroxide solution 3CP,
  • sweep 70 G,
  • modulation amplitude 20 G.

Low S/N Ratio

More reserach posibilities and new applications

Our eSPECT+ device allows you to lower the frequencies and at the same time collect high-quality signals with a great signal-to-noise ratio. Owing to that additional feature you will have a chance to examine creams, liquids, drugs and biological samples like zebrafish embryos.
