SCANNING SPECTROPHOTOMETER DOUBLE BEAM LABOMED.

Model UVS-2700 & UVS-2800
UV-VIS Split Beam 8 Auto Cell

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 can be used as an accurate system for qualitative and quantitative analysis of analytical test, Biochemistry, Chemistry, Clinical Analyisis, Pharmaceutique and Agriculture Labs, Quality control, Industry and research.

Spectro UV-Vis Split Beam PC can perform DNA/ RNA measurement, that can also be printed using an external HP 600/ 800 series printer.

Functions
# Photometric Measurement: Rapid and accurate measurements of transmittance and absorbance for samples and selected wavelength are available.

- This module allows successive and automatic calibration and measurement of up to seven samples with the built-in 8-cell sample holder.
- Direct concentration results can be produced by simply entering the K-factor.
- Printout of Measured data with sample numbers in a tabular format.

# Spectrum Scan: Spectra of samples on any range between 1100nm ~ 190 nm can be measured with real time visual display of spectral curves on the large LCD screen.

- Such operating parameters can be selected, as photometric mode, wavelength range, ordinate range, sampling interval and scanning speed.
- Picking out and printout of peaks and valleys for spectral curves.
- Printout of spectral curves to a printer with A4 paper.

# Quantitative Measurement: Use a calibration curve to determine the concentration of unknowns at the user-selected wavelength.

- The regression of calibration curve can be made with up to 8 standards and the linear correlation coefficients be offered.
- The plot of a calibration curve is displayed on the large LCD screen.
- Instant concentration results can be produced by simply entering K-factors.
- Successive and automatic calibration and concentration measurement up to seven samples are available by the built-in 8 cell sample holder.
- Printout of the table of measured concentrations and K-factors of a calibration curve.

# Windows Software: Such operations as photometry measurement, spectrum measurement, quantitation measurement and kinetic measurement are offered in the UV-Win Windows application.

- Up to 10 Spectra and time-course curves can be measured and recalled in memory with data-handling of arithmetic calculation, logarithmic calculation, reciprocal calculation, smooth, derivative ( 1t-4th) , Abs to/ from % T conversion and peak pick.

- Up to 24 standards can be entered and measured for fitting of calibration curve with order of 1st ï ¿ ½ ï ¿ ½ ï ¿ ½ 4th.

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