Applications

Alanine Dosimetry System

Magnettech ESR5000 is a complete alanine-EPR dosimetry system for routine dosimetry in industrial irradiation facilities, or for use as an in-house alanine reference dosimetry system.

Highest quality measurements:
The Magnettech ESR5000 instrument provides a
stronger measurement response signal than any other
bench-top EPR spectrometer on the market today, with
higher measurement sensitivity.

Cuts measurement time in half:
The Magnettech ESR5000 EPR system reduces measurement
times in half, from 40 seconds down to 10
seconds or less.

Reliability:
the new EPR spectrometer uses a solid-state technology,
to provide a more rugged industrial instrument for
higher reliability and uptime > 99 %.

Flexibility:
Accommodates a wide variety of commercially available
alanine dosimeters with specialized holders.
Remote accessibility:
IP based system allows remote operation and technical
support from anywhere in the world.

Accessories

Flat Cell

Optimize sensitivity for samples that are in water or other polar solvents. A special holder is provided to achieve consistent sample positioning and to prevent breakage

Variable Temperature Unit

The nitrogen variable temperature unit uses liquid or gaseous nitrogen to cool and heat the sample in the range of 93 – 473 K. The compact, digital temperature control system makes use of nitrogen for safe and stable temperature control

Autosampler

Automated handling of up to 26 samples in quartz tubes 3 – 6 mm diameter, precise height positioning within resonator for highest reproducibility

Bio Temperature Controller

Used to keep biological and biochemical samples constantly under conditions of elevated metabolic activity. Temperature range: 295 - 333 K

Automated Goniometer

Fully automated angular rotation of sample, step size 0.1° to 180°. Automatic readjustment of the spectrometer before every measurement.

Rack for Horizontal Orientation

Specialized mounting for horizontal orientation for use with viscous media, tissues and cell suspensions

UV-Vis Irradiation System

For studies of photochemical radical reactions, photophysical production of excited paramagnetic states, suitable to trigger kinetic experiments. Features an integrated light source for sample irradiation, holder for precise positioning, high power LED, and exchangeable light intensity from 100% to 0%

Tissue Cell

Used to analyze skin sections, organ slices, pastes and emulsions as well as plant tissues and conducting foils

Finger Dewar

For sample cooling at fixed temperature of 77 K. Maximum volume of liquid N2 – 50 mL with a storage time up to 2 hours
