The Junior is a small portable tube luminometer designed for all common applications using glow-type bioluminescent and chemiluminescent reagents. Excellent performance, its small size and low weight paired with battery operation make the Junior a highly versatile instrument which can be used in any location – the laboratory, on site or outdoors. The Junior is used in a number of diverse fields of application including biomedical research, clinical diagnostics, hygiene monitoring, process control in biotech and environmental monitoring of water quality. The detection unit of the Junior consists of a state-of-the art ultra fast single photon counting photomultiplier with low noise. For demanding applications a “high sensitivity” model with a specifically selected ultra low noise detector i...Read more

Berthold Technologies single photon counting electronics and selected photomultiplier tubes with low noise and high saturation level ensure a wide dynamic range. The user will benefit by being able to measure low signals as well as high ones without the need to change any settings.
A stringent selection of detectors ensures a neglectable day-to-day variation of instruments, thus providing a high reliability of the measurements.
The unique design of the measuring chamber allows the use of a variety of different sample tubes and sizes. Besides the traditional lumi vials, microcentrifuge tubes (Eppendorf cups) and capped 4 mL vials can be used.
The Junior can be operated independently from a mains supply for many hours as it is equipped with rechargable batteries. In the lab the instrument can be connceted to a mains supply thereby automatically recharging the batteries.
With a weight of only 2 Kg and its small size the Junior can be carried and taken to the sampling location for measurements on site. A metal transport case providing space for the Junior and accessories is an ideal solution for outdoor use.
The lean and dedicated software is operated through a membrane keypad. The well arranged graphical display shows selected protocol, sample locatioon and number and the RLU value of the measurement. In addition a set consisting of a red, a yellow and a green LED unmistakably indicates whether a signal and thus a sample is above an upper limit (red), below a lower limit (green) or in between (yellow).
The graphic display is illuminated only when the instruments is in use. As soon as the instrument is idle the illumination is turned off to save energy.
Up to 2,000 measurement results will be stored in the instrument´s memory. Criteria like time of measurement and measurement location may be used to search for results in order to review them. The same criteria may be applied to select results for being downloaded to a computer. The PC software Winterm arranges the data properly and transfers them into an EXCEL spreadsheet.
