Portable Tube Luminometer

Junior is a small portable Tube Luminometer designed for all common applications using glow-type bioluminescence and chemiluminescence. Excellent performance, small size, low weight and battery operation make the Junior a highly versatile luminometer which can be used in any location.

It can be used in a number of diverse fields of application including

  • Biomedical research
  • Hygiene monitoring
  • Process control in biotech
  • Environmental monitoring of water quality

Use it in the laboratory, on site or outdoors: the Junior is an all-purpose luminometer.

  • Enzyme activities
  • DNA probe assays
  • Mycoplasma detection
  • Luminescent Immunoassay (LIA)


  • State-of-the art ultra fast single photon counting photomultiplier with low noise
  • “High sensitivity” model with ultra low noise detector available: detection limit <50 amol ATP



  • Neglectable day-to-day variation of instruments
  • High reliability of the measurements



Several sample formats can be used:

  • Lumi vials
  • Micro centrifuge tubes (Eppendorf cups)
  • Capped 4 mL vials


  • Lightweight (only 2 kg)
  • Small size
  • Metal transport case for Junior and accessories


Ease of Use

  • Display shows selected protocol, sample location and number, and RLU value of measurement
  • Red, yellow and green LEDs indicates whether a sample is above an upper limit (red), below a lower limit (green) or in between (yellow)


Smart Memory

  • Storage for up to 2,000 measurement results
  • Criteria like time of measurement and measurement location may be used to search for results to review or download them
