Hitachi UV-Visible/NIR Spectrophotometer U-3900

Hitachi UV-Visible/NIR U-3900 Spectrophotometer (UV-Vis/NIR) 

Please contact our Sales Team with your laboratory requirements and specifications including PC equipment and software.

Covers a wide variety of analysis needs from liquid samples to solid samples. Line-up of two types that can be selected in accordance with the measuring object and application. For use in a wide range of fields that focus on water quality, the environment, biotechnology, pharmaceuticals, materials, etc.

• Measurable over a broad absorbance range thanks to low stray light and low noise. (Model U-3900: -3.8 to 3.8 Abs, 0 to 300%T Model U-3900H: -5.5 to 5.5 Abs, 0 to 300%T)
• Stable monochromator in double beam optics (Baseline flatness Model U-3900 : within ±0.0003 Abs, Model U-3900H : within ±0.0004 Abs)
• Simple instrument control and diversified quantitative analysis supported by UV Solutions program for U-3900 (in connection with PC)
• A full range of accessories for covering both liquid and solid sample measurements

FEATURES

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.

OPTIONS:

Enhanced Large Sample Compartment Accessory

When installing this enhanced sample compartment and additional accessories in U-3900/3900H UV-VIS spectrophotometer, you can measure the reflection characteristic, polarization property caused by incidence angle and transmission of solid sample and optical component, like reflected plate.
To use 5°/45°specular reflection accessory and 10 mm rectangular cell, these accessories have to be purchased separately.
