Halo DB 30 Spectrophotometer

 UV / Visible Double Beam Spectrophotometer

The next generation Halo DB-30 double beam spectrophotometer boasts superlative performance characteristics for applications demanding the utmost sensitivity by combining higher signal to noise ratios with minimal stray light.  This warrants the Halo DB-30 suitable to many diverse fields and industries such as pharmaceutical, food, sanitation, environment, biology, agriculture, geology, mineral, petrochemical, optical, life science, education, manufacturing and many others.

Halo DB 30 Spectrophotometer
 Exceptionally Low Stray Light
The intricate but elegant and innovative optical pathway is engineered to deliver outstanding double beam performance characteristics, in particular stray light which achieves an impressive low 0.010%T. The outcome is an increase in the linearity of absorbance characteristics for most samples thus increasing the scope of analytical applications particularly at higher concentrations.
 Spectral Features

The asymmetric monochromatic with long focal length results in improved sensitivity.  Up to 6 slit widths are selectable and switchable (with the highest achievable resolution of 0.1 nm) thus allowing for the optimization of different applications.

Other specifications include an impressive wavelength accuracy of 0.3nm, noise level 0.0003Abs (500nm), wavelength repeatability of 0.1nm for the accuracy and reproducibility of analytical data and an absorbance range of -4 to +5 Abs for the analysis of high absorbance samples without the need for further dilution.

 High Scan Speeds and Resolution
Select from 8 scan speeds starting at a high resolving 1nm/min.  Coupled with the precise fine tuning of the photomultiplier tubes, a wavelength resolution of 0.1nm is maintained at even the fastest scan speed of 2,000nm/min
 Powerful UV Detective PC Control
The Halo DB-30 is PC controlled using the UV Detective software (included with the instrument). UV Detective can also operate optional accessories such as the sample sipper and 6-cuvette holder.
 Dual Lamp Advantage
By virtue of the long life, halogen tungsten and deuterium lamps, the Halo DB-30s wavelength range extends from 190nm - 1,100nm.  Furthermore, the dual lamp system results in higher accuracy than corresponding xenon lamps.  Lamp switching is automatic and selectable from a wavelength range of 325nm to 370nm.
 Validation Functions
To ensure optimum instrument performance, self-diagnosis incorporating a number of parameters and wavelength calibration are automatically initiated upon start-up.  The Halo DB-30 with the UV Detective software is equipped with a GLP/GMP feature for analyses requiring validation and auditing.  Parameters such as wavelength accuracy, wavelength reproducibility, band pass, baseline flatness, baseline stability and noise level can be all validated and the audit report printed.
