TU-1800PC/1800SPC
UV-VIS
Spectrophotometer
--------------------------------------------------------------
The
TU-1800PC/1800SPC is our company’s 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. |
|
*
Versatile application software. The
UV-Win application software is made in the
Windows format, offering an extended range
of instrumental control and data processing.
*
Quality components. Many key components
are chosen from some of the world’s best
manufacturers; these include the deuterium
lamp, PMT and holographic grating. Careful
selection of these components ensures the
instrument’s dependability, accuracy, and
maximizes lifespan.
