Extract

"A standard IX83 Olympus inverted fluorescence microscope was used, which contains an epifluorescence illumination from a LED light source (CoolLED pE-300white) accompanied by different fluorescent filters for DAPI (narrow band UV excitation, with excitation filter BP360-370, dichroic beamsplitter DM410, barrier (emission) filter BA420-460), FITC (narrow band blue excitation, with excitation filter BP470-495, dichroic beamsplitter DM505, barrier (emission) filter BA510-550), TRITC (narrow band green excitation, with excitation filter BP540-550, dichroic beamsplitter DM570, barrier (emission) filter BA575-625), and Mcherry (with excitation filter BP565-585, dichroic beamsplitter DM595, barrier (emission) filter BA600-690)."

Sustainability

Did you know that LED illumination systems help laboratories reduce their carbon footprint, protecting laboratory staff along the way?

Toxic mercury-based microscope illuminators are bad news for the environment, draw a lot of power and have a short lifetime.

LED illumination systems are cleaner, have a long lifetime and use less power. Our pE-300 Series is also ACT label certified and is a natural choice for labs who want to play their part in helping the environment.
