The Waters 2475 Fluorescence Detector offers unsurpassed sensitivity for quantifying low concentrations of target compounds, whether naturally fluorescent or derivatized with a fluorescent tag. The 2475 FLR Detector sets the standard for fluorescence method development with 3D and “on-the-fly” spectral scanning for determining the optimal emission and excitation wavelengths, and has the ability to monitor up to four independent wavelength pairs.

• Innovative axially illuminated flow cell designed for less dispersion, less stray light, less volume, and more pathlength for maximum sensitivity
• Three-dimensional spectral scanning for faster method development and optimization, and enhanced peak identification
• Single or multi-channel operation monitors fluorescence at one or more discrete wavelength pairs
• Low noise performance - Less stray light due to orthogonal optics and the use of mirrors, not lenses, minimize scatter

Description:

This compact device is the ideal external light source for fluorescence excitation in microscopy. Coupling is preferably achieved via liquid light guides. The average service life of a lamp is 2,000 hours. The optimised internal air flow cools the lamp and enables quiet operation. A resettable operating hour meter shows lamp operating hours. The brightness of the lamp output can be varied in 5 steps (0-100%) by means of a mechanical dimmer unit. An ultra-fast shutter opens or closes after activation with approx. 6 ms. The shutter is actuated by means of an appliance switch, but is also possible externally by means of a remote control input or CAN-BUS connection. This compact light source is available as a VIS or UV version in addition to a version that permits the coupling of multi-pin liquid light guides.

Specifications:

• Dimensions (H x W x D): 210 x 130 x 290 mm
• Weight: 4.7 kg
• Ambient Temperature: 0°C to 40°C

The Lumen 200 Fluorescence Illumination System is a powerful, cost effective alternative to standard 100 Watt mercury and halogen lamphouses. The combination of Prior's proprietary 2,000 hour life, 200 watt metal arc lamp and two or three meter liquid light guide provide unrivalled versatility and illumination power. The Lumen 200 utilizes a metal halide lamp rather than the more traditional high pressure mercury or xenon burners. This means 2000 hours of stable output compared to a maximum of 300 hours for a mercury lamp. 

Specifications:

• Voltage: 100-240V
• Current: 2A
• Frequency: 50-60Hz
