Design Features

Instrument Specifications

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.

Frequently Asked Questions

GloMax® 20/20 Frequently Asked Questions
What is the price of the GloMax® 20/20 Luminometer?

The price may vary based on your application(s) and requirements. To receive a quote customized to your needs, use our online quotation form.

What is the detection system of the GloMax® 20/20 Luminometer?

The GloMax® 20/20 has a photomultiplier tube (PMT) detector. Because of its proprietary design, this detector offers both superior sensitivity and dynamic range.

How many injectors can be installed in the GloMax® 20/20 Luminometer?

The GloMax® 20/20 Luminometer accommodates one or two automatic injectors.

When/Why would I need an automatic injection system?

An automatic injection system is recommended when measuring flash luminescent reactions and when the assay requires high precision and reproducibility. Using an automatic injection system guarantees a consistent, precise injection rate and volume that is independent of the operator's skill or precision. Also, when working with a high sample load, automatic injection will save analysis time.

What are the advantages of internal automatic injectors versus external automatic injectors?

The GloMax® 20/20 internal automatic injectors permit dark-adaptation of the injectable reagents. The reagent supply remains in a protected, dark space inside the GloMax® 20/20 during the experiment. Because many reagents are light-sensitive, equilibrating the reagents to dark conditions allows for maximum reproducibility. Other luminometers rely on external automatic injectors, which draw reagents from a supply outside of the luminometer and do not protect reagents from the influence of ambient light. Internal injectors shorten the supply line length and reduce dead volume.

What types of test tubes can the GloMax® 20/20 Luminometer read?

The GloMax® 20/20 can read any clear 1.5ml microcentrifuge tubes, 35mm petri dishes, 12 × 50mm test tubes (optional) and minicell vials (optional, Fluorescence).

What operating software controls the GloMax® 20/20?

The GloMax® 20/20 has a touch screen-based Graphic User Interface (GUI). The GUI controls the instrument, reports data on the screen and sends data to a printer or computer.

Do I need to change anything for power requirements in different countries?

No, the GloMax® 20/20 has an internal universal power supply. Simply use the proper AC adaptor.

What is the GloMax® 20/20 Light Standard?

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.
