Promega luminometers include microplate and single-tube luminescence detection systems optimized for use with Promega assay chemistries. These instruments offer high sensitivity, pre-loaded protocols, and integrated data analysis—giving researchers a simple way to get better data and connect to manual or automated laboratory workflows. 

The GloMax® 20/20 (single-tube) Luminometer is popular with labs that have low throughput needs. It provides sensitivity down to 1 x 10-21 moles luciferase and an 8-log dynamic range. The GloMax® 20/20 reads one sample at a time and can use microfuge tubes, 12 x 50 mm tubes or 35 mm petri dishes as the input vessel.

For higher throughput, we offer three microplate luminometer options. GloMax® Navigator is a dedicated microplate luminometer;  GloMax® Discover and GloMax® Explorer are multimode readers offering luminescence, fluorescence, absorbance, BRET and FRET detection options. These plate readers provide high sensitivity detection, an easy-to-use interface, and full integration with Promega assay chemistries.

What is a Luminometer?

A luminometer is an instrument capable of detecting photons of light that are emitted from either a chemical or enzymatic reaction. This type of instrument can be a very useful piece of equipment for a variety of laboratories, including life science research, clinical, and applied areas such as food or water quality testing. Luminescence is typically a more sensitive detection modality than either fluorescence or absorbance-based methods, making it especially useful for studying cellular health and metabolism, genetic reporter assays, and even biochemical assays.

As light is emitted from a chemical or enzymatic reaction, the individual photons are collected by a detector, commonly either a photodiode or photomultiplier tube. This light is quantified as a Relative Light Unit (RLU) and is directly proportional to the concentration of the amount of luminescent material in the sample.  

When choosing a luminometer, important factors to consider include sensitivity, dynamic range and cross-talk performance, as the performance of the instrument can greatly impact the success of your assay results.
