Description
Design Features
To achieve the GloMax®-20/20's high sensitivity, the luminescence channel is positioned directly below the sample well. These conditions maximize light capture. In addition, a low-noise photomultiplier tube ensures that collected light is not compromised. The dynamic range of the GloMax®-20/20 is more than adequate to cover common luminescence applications, thus reducing the need to dilute samples.
The GloMax®-20/20 Luminometer Light Standard provides an external control to verify performance. Some labs require this additional verification procedure. Reading the light standard before taking measurements is a quick and easy way to ensure quality control of reproducibility, sensitivity, and linearity of measurements.
Optional Fluorescence Modules add functionality to the GloMax®-20/20. The modules are designed to measure common fluorescence applications using excitation wavelengths in the near UV or Blue light range. The Fluorescence Modules provide sensitive measurements of DNA, RNA, or protein quantitation dyes.

The GloMax® 20/20 Light Standard is designed to provide a quick and easy way to verify the performance of the GloMax® 20/20. It allows you to check the reproducibility, sensitivity and linearity of a luminometer in less than 30 seconds. The Light Standard consists of three highly stable light sources that simulate luminescence samples at three different signal levels. It can be used for both short-term and long-term stability studies of the detection system.
The GloMax® 20/20 Fluorescent Module is a snap-in device that allows you to measure fluorescent assays with GloMax® 20/20. There are two models, UV and BLUE.
The Fluorescent Modules and the Light Standard are sold separately. You can purchase either the Fluorescent Module or the Light Standard when you order the instrument or anytime in the future.
