Features

In addition to the common features of all Microplate Reader instruments, the Varioskan LUX offers:

Automatic dynamic range selection

Designed to automatically select the optimal reading range based on the signal intensity in each well. This feature saves time and reduces the risk of loss of sensitivity or over-saturation of signals.

 

Integrated gas control

The ability to control O2 and CO2 levels in your microplate reader replaces the need for constant handling of plates between the incubator and reader, and helps to ensure that cells remain alive throughout the experiment.

Smart safety controls

Automatic safety checks designed to alert you of potential problems before they happen. This decreases the potential of a range of experimental errors, from user mistakes to power outages.

 

Flexible wavelength selection

The instrument selects the measurement wavelength using filters or monochromators, depending on which is optimal for each measurement technology.


Available measurement technology configurations

All configurations available with top or top and bottom fluorescence intensity reading; none, one, or two dispensers; and optional integrated gas modules.
