"The Ideal 'Everywhere' Spectrometer"

Extend your laboratory’s capabilities with the next-generation benchtop EPR / ESR spectrometer from Bruker.

The versatile ESR5000 is an easy to use research grade instrument with sensitivity and reliability for demanding applications.Size matters when lab space is scarce but so does ease of use and performance. The ESR5000 addresses this as an easy to use, compact, and powerful research grade instrument. Focus on your research and not on the instrument with ESRStudio, the most modern and dynamic software for ESR / EPR measurements. The simple and intuitive user interface doesn’t require you to be an expert in spectroscopy to get accurate results.

Need to take Liquid Helium (He) or Nitrogen (N2) measurements? The ESR5000 with optional accessories (He Cryostat / Temperature Controller) allows you to meet these requirements.

Looking for Quality Assurance? The ESR5000 also addresses standards such as EN 1786, 1787, 13708 related to irradiated food testing.

• Save space and easily mobilize with a compact design
• Simple and intuitive operation puts focus on research not instrument operation.
• Accommodate variable research applications with a wide range of accessories

"The Most Sensitive TLD/OSL Reader"

Thermal Stimulation

Ceramic heating element allows highly reliable and more consistent measurements. The heating element is cooled by continuous flow of nitrogen or compressed air. Thermoluminescence (TL), preheat (PH) including elevated temperature luminescence measurements (OSL, RL, etc.) as well as elevated temperature irradiation (at ionizing irradiation and “solar-light” position) are possible during any part of a heating/cooling cycle, which is almost freely programmable including non-linear heating/cooling functions.

Optical Stimulation (OSL)

All Lexsyg Smart and Lexsyg Research TL/OSL readers can be equipped with an interchangeable OSL unit containing up to three stimulation wavelengths. These are provided by high power stimulation elements optionally as LEDs or laser diodes. The integration of photo diodes provides the feedback for power control of each individual element, guaranteeing a stable stimulation source, independent of element aging.

 Looking for Quality Assurance? The Lexsyg Smart addresses standards EN 1788 and EN 13751:2009 related to irradiated food testing.

• Compact design: Provides thermal and optical stimulation for up to 3 different wavelengths
• No crosstalk: Independent operation of measurement chamber and sample changer ensures absence of stimulation and radiation crosstalk
• Flexibility: Software controlled switch of detection filters within a measurement sequence
• Homogeneity: Highly homogeneous and stabilized optical stimulation provides identical measurement conditions
• Accessibility: IP based system allows remote operation and technical support from anywhere in the world
