Hitachi Spectrophotometer U-3900H
comes with UV Solutions 4.1
IMPORTANT!! YOU WILL NEED A PC WITH WINDOWS 7-32bit.
will not work with any other version of Windows.
This Spectrophotometer is in very nice condition, and will work upon delivery. It comes from a working lab at UTMB Galveston. This unit has been tested and functions properly. Powers on, communicates with PC (not included) utilizing the UV Solutions software, and is able to properly analyze samples. Deuterium Lamp has 49 hours on it. More information can be found on Hitachi's website, but below is some highlights. This is the "H" model with double Monochrome setup. Comes with wires, user manuals, software, and sample tubes
Possible to perform measurements in a wide absorbance range with low stray light and low noise
The larger the amount of transmitted light, the lower the noise of the obtained absorption spectrum so that a wider absorbance range can be measured.
Measurements of high concentration samples can be performed over a wider concentration range.
Stable spectrometer with double beam optical system
The light source uses a WI lamp (visible range) and a D2 lamp (ultraviolet range) that switches wavelength depending on the measurement. The double beam system divides the monochromatic light so that the diffraction grates into the control and the sample with a rotational mirror, guiding the light to the sample chamber.
Single Monochrome Type U-3900 uses a spherical surface mirror in front of the entrance slit, while the Double Monochrome Type U-3900H uses diffraction grating.
UV Solutions for U-3900 (PC connected) allows for easy device control and supports various quantitative-analysis functions
Special operation software that offers substantial functions such as measurement data comparison and a preview function that allows for a more powerful analysis.
Substantial accessories for both liquid and solid measurements.
There is an abundant lineup of accessories to accommodate multiple sample and micro sample applications, etc.
Loaded with aberration-corrected concave grating
The U-3900/3900H provides aberration-corrected concave gratings with a Seya-Namioka Mount for the spectrometer. Both condensing and dispersing functions allow for a bright optical system, but with fewer mirrors so that light loss and aberrations are reduced.
Two types of optical systems: Single Monochrome (U-3900) and Double Monochrome (U-3900H)
A lineup of two models with different spectrum systems: Single Monochrome (U-3900) and Double Monochrome (U-3900H).
The Single Monochrome is suitable for a low-concentration sample since sample light energy is stronger compared tothe Double Monochrome. The Double Monochrome is suitable for a high-concentration sample since it can measure high absorbance with little stray light.
