U-3900/3900H Spectrophotometer |
 |
 |
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.
This product is a PC controlled system. |

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. |

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 10mm rectangular cell, these accessories have to be purchased separately. |
