GloMax® 20/20 Single Tube Luminometer

An ultra-sensitive, versatile, and affordable single tube luminometer for Life Science research.

8964CA_GloMax_2020

The GloMax® 20/20 Luminometer replaces the Turner BioSystems 20/20n Luminometer. Same instrument... new look!

OVERVIEW

The GloMax® 20/20 Luminometer is designed to provide ultra-high performance for bioluminescent and chemiluminescent assays. In addition to high performance, the GloMax® 20/20 blends user-friendly operation and a small footprint with flexible purchasing options. The result of this design is an instrument with superior performance that is easy to use, affordable, and can be customized to your lab's needs.

GloMax 20/20 Single Tube Luminometer

SUPERIOR PERFORMANCE

The GloMax® 20/20 Luminometer provides exceptional sensitivity for all luminescent assays. Proprietary circuitry and an advanced photon-counting photomultiplier tube (PMT) produce unmatched signal-to-noise ratios. The GloMax® 20/20 has a detection limit of 1 x 10-21 moles of luciferase, making it one of the most sensitive tube luminometers available.

With greater than 8 logs of linear dynamic range, the GloMax® 20/20 Luminometer can measure both dim and bright samples without dilution. The extended dynamic range spans the full range of virtually all chemiluminescent and bioluminescent assays, eliminating the need to dilute samples or manage detector-driven gain changes.

EASE OF USE

The GloMax® 20/20 is designed to be put into use straight from the box without the need to read a manual or obtain special training. To achieve this plug-and-play usability, the GloMax® 20/20 combines a color touch screen with an intuitive user interface. The interface makes running samples and viewing data fast and simple while also maintaining the flexibility needed for advanced or custom protocols.

VERSATILITY

The GloMax® 20/20 is a versatile addition to any lab. The optional single or dual auto-injectors allow measurement of either flash or glow-type luminescence, while the flexible sample compartment accommodates 1.5 ml microcentrifuge tubes, 35 mm petri dishes, and an optional 12 mm x 50 mm test tube adapter. It is also possible to measure the light output from both liquid and solid samples. In addition, the bottom reading design means there are no minimum volume requirements. For added functionality, two fluorescent modules are available, expanding the GloMax® 20/20 functionality to common fluorescence applications.

FLEXIBLE SAMPLE COMPARTMENT

The GloMax®-20/20 accommodates 1.5 ml microcentrifuge tubes, 35 mm petri dishes, and 12 mm x 50 mm test tubes (with optional adapter). It is also possible to measure the light output from both liquid and solid samples.

LID START

Adjust settings to start measurement immediately after the lid is closed.

TOUCH SCREEN

The touch screen allows simple navigation between screens for setting parameters, storing protocols, and starting runs.

DATA HANDLING

The GloMax®-20/20 stores up to 18 protocols and displays data from the last 20 measurements on the LCD screen. Spreadsheet Interface Software to connect to a PC, and an optional thermal printer are also available for easy data exporting.

INTUITIVE USER INTERFACE

Luminescence
Choose from pre-loaded Promega protocols, the default protocol, or create your own custom protocol. Use the Instrument Control screen to edit parameters, then press MEASURE LUMINESCENCE.

Fluorescence
Snap in one of two Fluorescence Modules, power cycle the instrument, and the GloMax®-20/20 automatically adjusts screens and options.

Injector Control
Control injectors from the touch screen. Both PRIME and FLUSH commands are integrated into the software.

SINGLE OR DUAL AUTO INJECTORS (Optional)

Injectors dispense fluids from 25 - 300 µl and enable detection of flash-based luminescence or dual-reporter assays. Completely visible plumbing allows inspection of tubing and tips during flushing and priming.

LUMINESCENCE APPLICATIONS

  • Dual Reporter Assays
  • Cell Viability/ATP Assays
  • Kinetics Assays
  • Intercellular Ca+2 Assays
  • Immunoassays

Luminescence
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 GloMax®-20/20 has greater than 8 logs of dynamic range. This dynamic range is more than adequate to cover common luminescence applications, thus reducing the need to dilute samples.

Luminescence Light Standard
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.

FLUORESCENCE APPLICATIONS (Optional)

  • DNA/RNA Quantitation
  • Protein Quantitation
  • Gene Expression

Fluorescence
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.
