The TU-1800PC/1800SPC is our companys popular UV-VIS spectrophotometer. Its optical system adopts a split-beam measurement optical system, detector for two highly sensitive silicon diodes; instrument operations are controlled through the PC, using UV-WIN, a WINDOWS platform software. The instrument features an 8-cell holder, accessible light-source chamber. TU-1800PC/1800PCS UV-VIS spectrophotometer performs photometric measurements, spectrum measurements, and quantitative measurements.
It is easily operated, features excellent performance, automatic 1100nm-200nm wavelength scan, abundant measurement features, and data-processing applications. The practical TU-1800 series is suitable for medical, chemical, environmental, agricultural, or biological analytical work.
Features
|
* Low Stray Light and Wide photometric range. The high-performance blazed holographic grating reduces stray light of the instrument and widens the photometric range.
* Enhanced baseline stability. The dual beam monitoring ratio system enhances baseline stability.
* Heightened resolution. The large-diameter light path magnifies the instrument\'s energy, reduces noise and enhances resolution.
* Automatic sequential measurement. The automatic eight-cell sample holder carries out automatic measurement of eight samples in succession. It also features a one-touch measurement of the dissolution of six drug samples and a blank
* User-friendly light source. The socket deuterium lamp and socket tungsten lamp facilitates easy light source replacement, easy maintenance, and reduces operation error |
