GloMax®-Multi+ Microplate Multimode Reader with Instinct®

GloMax Multi Plus


Luminescence Module
(Factory Installed)

>8 Logs Dynamic Range
Dual-masking System Reduces Crosstalk
3 x 10-21 Moles Luciferase Detection or 1 x 10-18 moles ATP

To achieve the sensitivity of a dedicated luminometer, the luminescence channel is separated from other measurement technologies and positioned directly above the sample well. These conditions maximize light capture for the best possible sensitivity. In addition, a low-noise photomultiplier tube ensures that collected light is not compromised in any way. This design makes the GloMax-Multi+ Microplate Multimode Reader between 10 to 1000 times more sensitive than competing multimode luminometers. In addition to high sensitivity, the GloMax®-Multi+ boasts greater than 8 logs of dynamic range, eliminating the need to dilute samples or manage detector-driven gain changes. The photomultiplier tube automatically adjusts for the optimum reading of bright or dim samples. This means that the GloMax®-Multi+ is capable of achieving a reading range 2 - 3 logs more than that of competing multimode luminometers.

Fluorescence Module
(User Installable)

Epifluorescent Detection (top reading)
Easy Optical Kit Switching
Wavelength-matched LEDs Ensure High Sensitivity

To achieve high performance, the Fluorescence Module uses powerful light-emitting diodes (LEDs) as excitation sources. LEDs have very specific light-output profiles that closely match the excitation profiles of commonly used fluorescent molecules. LED usage increases sensitivity by fully exciting the fluorophore and reducing non-specific light leakage, a common problem when using broad-spectrum light sources. Five standard optical kits are available to measure the most popular fluorophores. In addition, custom optical kits can be readily made for non-standard applications. Optical kits can be easily exchanged in seconds and built-in software ensures that the installed optical kit matches the selected protocol. Designed as a user-installable module, you can either buy the Fluorescence Module with your GloMax®-Multi+ instrument or add it to your system later when you are ready to run fluorescence experiments.

Absorbance Module
(User Installable)

UV-Visible or Visible Modules
Flexible Filter System
Reads Single or Dual Wavelengths

The GloMax-Multi+ Microplate Multimode Reader provides you with two different options for making photometric measurements. A Visible Absorbance Module (450 - 750 nm) or a UV-Visible Absorbance Module (200 - 1100 nm). Both modules are user installable, so there is no downtime or need for a service call.

Both the Visible and UV-Visible Absorbance Modules come factory-installed with four common filters: 450, 560, 600, and 750 nm wavelengths. The UV-Visible module also comes with a 260 and 280 nm filter. In addition, you can customize either module by inserting a filter of your choice into either of two removable filter paddles.
