X-Cite® exacte

Product Announcement from Lumen Dynamics Group Inc.

X-Cite® exacte -Image

The Revolutionary New Light Source for Fluorescence Illumination - The X-Cite® exacte employs a DC-powered mercury lamp coupled with patented Closed-Loop Feedback technology to provide ultra-stable illumination, for imaging protocols lasting from milliseconds to days. With the X-Cite® Radiometer, light output can also be calibrated in absolute power units (watts), ensuring truly repeatable experiments.

The X-Cite® exacte has the convenience of pre-aligned, long-life lamps and easy installation combined with innovative functions in the newest generation of mercury arc fluorescence illuminators.

Setting a new standard. Stability. Control. Repeatability.
