Spectro UV-Vis Dual Beam PC
Scanning Spectrophotometer
UV-VIS Split Beam8 Auto Cell
Model UVS-2700 & UVS-2800
|
Spectro UV-Vis Split Beam PC is a precise scanning Spectrophotometer with a new design of 8 microprocessor automatic 2 row cell holder that moves noiseless with a special membrane. This Split Beam Spectro has a dual detector and a very accurate system.
Spectro UV-Vis Split Beam PC is microcomputer-controlled and has a large LCD display to work independently. It can also be linked to a computer and a printer to show Photometric and Spectral data in the PC monitor. This connection is controlled by the RS232 AND USB interface, compatible with Windows XP, & and 8, using the new UVWin 6.0 UV-VIS application software.
Spectro UV-Vis Split Beam PC is also capable of performing kinetic test by an optional Peltier constant temperature system, and can test flow through liquid by the optional Sipper Flow Through System.
Spectro UV-Vis Split Beam PC can be used as an accurate system for qualitative and quantitative analysis of analytical test, Biochemistry, Chemistry, Clinical Analysis, Pharmaceutical and Agriculture Labs, Quality control, Industry and research.
Spectro UV-Vis Split Beam PC can perform protein, nucleic acid, DNA/RNA micro and macro measurements, that can also be printed using an external HP 600/800 series printer or a PC printer.
There are 2 models of Spectro UV-Vis Split Beam PC available:
1) Spectro UV-Vis Split Beam PC with fixed bandwidth of 1 nm (UVS-2700).
2) Spectro UV-Vis Split Beam PC with variable bandwidth of 0.5, 1.0, 2.0 and 5.0 nm. (UVS-2800) is also available.
This Spectro can be used by itself or linked to a PC and comes with a USB interface to connect to the computer.
The operation manual is available in 18 available different languages.

Baseline Stability: The Split-beam monitoring ratio system enhances baseline stability.
Excellent Resolution: The big-caliber light path enhances the instrument’s energy, reduces its noise and raises its resolution performance.
Automatic successive measurement: The automatic eight-cell sample holder offers the automatic measurement of eight samples in succession. So it can bring about one-touch measurement of the solution of seven samples and a blank.
User-friendly light source: The light source performs an automatic interchange, selectable within the working range of the light source. The socket deuterium lamps and tungsten lamps facilitate light source replacement, simplify maintenance and reduce operation error.
Convenient Display: The large backlit LCD screen displays both photometric values and spectral curves.
Full use of Computer Technology: Being computer controlled with compatible with Windows XP, & and 8, using the new UVWin 6.0 UV-VIS application software, offering a wide range of uses and applications.
The key components are all adopted from the world famous manufacturer, such as deuterium lamp, silicon photodiode and holographic grating, which ensures the stabilization and credibility of the Instrument for extended life.
Computer System is optional (NOT INCLUDED).

OUR NEW SOFTWARE UV-WIN 6.0
WITH 3D SPECTRA
Now all Labomed, Inc. split and double beam spectrophotometers with our newly developed software called UV-Win 6.0 can be used with Windows XP, Windows 7 and Windows 8. It is capable of testing more applications with its RS-232 and USB connections, and supports the data export of measured results to the PC and then flash drive, when additional data storage is required. One of the new features is that it provides 3-D graphing of the spectral results.
