UV-VIS Double Beam PC Scanning Spectrophotometer UVD-2950

Spectro UV-VIS Double Beam PC Scanning Spectrophotometer UVD-2950 Labomed,Inc

Features

baseline Stability

The Double beam monitoring ratio system enhances baseline stability.

1nm fixed bandwidth New!

The Double 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.

2 Cell Holder

Spectro UVD-2950 has 2 cell holders for reference ( standard ) and sample.

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 RS-232 interface and working on the Windows platform with the UV/Win application software.

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 )

Software Specifications

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, if required, a USB flash drive, when additional data storage is required. One of the new features is that it provides 3-D graphing of the spectral results.

Monoprocessor Built-in Application :

Photometric Measurement

Measuring transmittance or absorbance at the current wavelength together with K factor calculations.

Spectrum Scan

Carrying out scanning of transmittance or absorbance on the selected wavelength range together with peak-pick module.

Quantitative Determination

Regression of standard curves and direct determination concentration of samples.

PC Windows Application Software ( RS-232 Interface ) to link Spectro to computer and printer :

Photometric Measurement

Measuring the photometric values at 1-10 wavelengths together with mathematical calculations according to entered quotations.

Spectrum Scan

Producing Wavelength scans within the operating parameters on samples together with powerful data handling facilities.

Quantitative Determination

Determination of unknown concentration with methods of 1-3 wavelength quantitation, together with fitting of calibration curve of 1st ~ 4th order.

Kinetics

Recording curves of changing photometric values of samples against timecourse at the selected wavelengths together with powerful data handling facilities.

Output

With the Windows clipboard, the measured data and graphics can be copied to other applications software for reports.
