Specord - Model 50 Plus - UV Vis Double-Beam Spectrophotometer
Dual-beam photometer with split beam technology for routine qualitative and quantitative photometric applications.
The SPECORD PLUS offers the right solution for numerous applications. Routine analysis or special application in chemistry, pharmacy, medicine, food control, environment, life science and many other areas – with SPECORD PLUS you are well prepared for all future requirements. UV/Vis spectroscopy is a method of molecular absorption spectroscopy with ultraviolet and visible radiation mainly on liquid samples measured in transmittance or absorbance. Measurements on solid and gaseous samples are also possible. Thereby, one can obtain qualitative information (like purity of substances, substances identification or binding conditions) as well as quantitative information (like concentration via endpoint measurement or via kinetic).
SPECORDPLUS is equipped with the comprehensive basic software ASpect UV, which already contains numerous specific tools for individual applications!
ASpect UV enables intuitive, precise work. It provides complete control, monitoring and logging of all processes from spectrometer to accessories and ensures compliance with FDA 21 CFR Part 11. The system can be connected to an existing LIMS.
Data can be exported in Excel format.
The basic software package contains the modules:
- Photometry - for quantitative analyses or biochemical evaluations
- Spectrum - for the evaluation and data treatment of spectra
- Kinetics - for the measurement and evaluation of time-dependent analyses
- Thermometry - for the measurement and evaluation of temperature-dependent analyses
- Colorimetry - for the determination of layer thicknesses, color coordinates and color numbers
Additional modules
- Validation software for checking specific device parameters using certified standards
- FDA 21 CFR Part 11 with user administration, audit trail function and electronic signature of measurement results for absolute data integrity

High-end optics
At the heart of all of our instruments, the optical components are quartz coated and equipped with high-quality encapsulation. They guarantee highest quality, maximum performance and extreme durability. The monochromator with imaging holographic grating enables stray light reduction and absolutely precise measuring results. The minimized number of movable components ensure best reliability, notably improved signal-to-noise ratio and best energy throughput.
Real double-beam
Real double-beam mode for highest precision and a better long-term stability by measuring the sample and reference signal at exact the same moment.
The measurement results always show a current comparison of both beams. This way lamp fluctuation and drifts are corrected by the second beam. Furthermore is a direct compensation of the blanc solution possible.
Convincing details
- Innovative CDD technology – two temperature controlled detectors for outstanding long-term stability
- Pre-adjusted and voltage stabilized radiation sources
- Internal holmium oxide filter for automatic wavelength calibration and for optimized wavelength accuracy and reproducibility
- Variable spectral resolution includes the smallest details of the spectrum (SPECORD 210 PLUS / SPECORD 250 PLUS)
The SPECORD PLUS is developed for user friendly operation:
