NOVEL-102S UV-Vis double beam spectrophotometer — 190–1100 nm, spectral bandwidth 2 nm
The NOVEL-102S UV-Vis double beam spectrophotometer measures every sample against a reference beam across 190–1100 nm. Deuterium and tungsten lamps, a Czerny-Turner monochromator with a 1200 lines/mm grating and a spectral bandwidth of 2 nm give stable UV and visible readings during long scans and kinetics; the wavelength is set automatically and everything is operated from the 8″ colour touch screen.
Double beam measurement for scans, kinetics and low absorbance
In a single beam instrument a change of lamp intensity after the blank appears directly in the result. The NOVEL-102S splits the light into a sample and a reference beam and measures both, so the baseline stays flat (≤±0.002 A) and drift stays below 0.0009 A/h. That matters for full-spectrum scans, long kinetic runs and samples with low absorbance — the typical work of a UV-Vis double beam spectrophotometer.

Why a UV-Vis double beam spectrophotometer
A UV-Vis double beam spectrophotometer compares the sample with the reference at every point of the measurement. Lamp warm-up, ageing and mains fluctuations are compensated, so a spectrum recorded over minutes or a kinetic curve over an hour is not distorted by the instrument. The NOVEL-102S brings this to routine laboratories at the price level of the NOVEL platform.
For series of samples with an automatic 8-cell holder choose the NOVEL-100S; for selectable bandwidth from 0.5 to 5 nm and the lowest stray light choose the NOVEL-900.
Cell holders and sample handling
The NOVEL-102S measures 10 mm cuvettes in a single cell holder in the sample beam; quartz cuvettes are used for the UV range, glass cuvettes for the visible range. 2 quartz and 4 glass cuvettes are included.

Operation and data
The NOVEL-102S is operated from an 8 inch touch screen: wavelength, method and units are set on the screen; spectra, regression curves and kinetic plots are shown while the measurement runs. Zero and 100 %T are adjusted automatically, and concentration is read directly or from a linear regression.
Results, spectra, regression equations and correction data are kept in the internal memory, so the instrument starts quickly. The deuterium and tungsten lamps can be switched separately to extend their life. Via USB the NOVEL-102S connects to a PC; a thermal printer and the COLO spectrum PC software are available as options.
