Beta Imager


Sensitive, real-time, precise, digital: the Beta Imager turns autoradiography into a fast and easy routine. With its multiple probe discrimination capacity, it extends the power of autoradiography to multiplexing.

       >> Description of the detection principle of the Beta Imager

Tritium detection 500 times faster than film

Tritium is a reliable beta emitter for measurement of iological samples. The problem is, detection is slow. Traditional film and phosphor imaging methods can take weeks to complete. But now, there is a better way to meet high throughput needs: Beta imager cuts tritium imaging from weeks to hours.

A versatile technology

  • ideal for tritium detection
  • detects all other usual beta emitting isotopes (14C, 32P,35S, 33P,125I)
  • detects electrons associated with gamma isotopes
  • detects positrons associated with PET isotopes

A wide range of applications

  • receptors binding
  • whole body sections
  • tissue sections on glass
  • any tissue sections
  • TLC plate
  • electrophoresis gels
  • hybridization membranes
  • ex vivo imaging after microSPECT or microPET


The very high sensitivity of the Beta imager cuts tritium imaging from weeks to hours
