Open Platform System
The advanced spectroscopic building block system for your lab
The Open Platform system comes with stabilized high output long life LED light source, a choice of 110 V or 220V power supply, liquid or solid sample holder, optical filters and all cables. Choice of software and spectrometer are available.
The Open Platform System from Wilson Analytical features an optical plate that allows the easy mounting of a selection of light sources, sample holders and spectrometers.
Custom designed and manufactured by Wilson Analytical
Optically stabilized, long life, high-intensity LED Light Sources
Individual LED wavelengths available in 365 nm (UV), 405nm (violet),
450 nm (blue), 520 nm (green), and 850 nm (near IR)
Polychromatic light sources using white-light LED (400 – 850 nm),
high-output tungsten-halogen incandescent (380 – 2500 nm),
or tungsten-deuterium UV-Vis (200-1100 nm)
Output modification is easy using 12.5 mm diameter round filters held in our original filter holder (Left)
For those who switch out filters regularly try the NEW Quick Release Filter Holder (Right)
Cuvette Holder for Liquids
The three-optical-port cuvette holder ensures easy measurements of liquids whether in fluorescence, absorbance or transmission configuration
Hinged, interlocked cap improves safety and spectral sensitivity
Anodized aluminum body and o-ringed sapphire windows in all optical ports ensure easy cleaning
Integrated spill-recovery drain system
Uses standard 10 mm square cuvettes and works with the Wilson Quick Release Optical Filter Holder
Port cap covers inactive ports to improve spectral sensitivity
The Solid Sampler is based on a rotating stage, which allows the user to test solids and liquids at various angles between the light source, sample and spectrometer.
The lid makes a light-tight seal around the sample, and both black (low internal reflection) and white (high internal reflection) versions are available.
The lid is interlocked for safety and to improve spectral sensitivity
Several different types of flat solid samples can be run:
13 mm cut solids or pressed powder pellets are held by the disk mount
Microscope slides or similar are held in the open mount
Spectra are collected off of the front side of the sample through the 10 mm aperture in the mount
Two types of cuvette holders are also available:
An “offset” cuvette holder for measurements directly off of the surface of sample in the cuvette. For front-surface measurements from materials that do not transmit light well, such as dark liquids, slurries and powders. It can be used for surface reflection or surface fluorescence analyses, as well as for electrochemical measurements when reflection electrodes are placed close to the wall of the cuvette.
A “centered” cuvette holder for regular solution analyses where the sample is transparent, and the incident light will pass through the liquid to allow for molecular excitation (for solution fluorescence) or for molecular absorption (for absorption or transmission measurements). Also for electrochemical measurements when the electrodes are designed to let light pass through
The inside of the Solid Sampler lid has three ports to let light in and out. Each port can hold a 12.5 mm optical filter or an attenuator:
Three different light attenuators are available: Disk A for no light transmission, Disk B for low transmission and Disk C for high light transmission.
All Flame-sized or larger Ocean Optics spectrometers work with the Wilson OPS. They are available for purchase through Wilson Analytical, or existing Ocean Optics units can be easily installed in the system
