Junior LB 9509 The portable tube luminometer

Junior LB 9509 The portable tube luminometer The Junior is a small portable tube luminometer designed for all common applications using glowtype 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 biotechnology and environmental monitoring, e.g....

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.

The lean and dedicated software is operated through a membrane keypad. The well arranged graphical display shows selected protocol, sample 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. location 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). A metal transport case providing space for the Junior and...

Applications Reporter Gene Assays In basic research of gene regulation as well as in drug discovery and recently even in clinical diagnostics luciferases, ß-glucuronidases, ß-galactosidases and secreted alkaline phosphatases have become standard tools offering high sensitivity and wide dynamic range. Dual reporter type assays, e.g. DualGlo™ reporter gene assay, are popular as they provide an internal control for transfection efficiency or general expression level and cell viability. Chemistries with a stable light emission can be measured with the Junior by adding the reagents manually....
