Halo DB-20\/DB-20S<\/strong>\"\"<\/h1><\/dd>
<\/dd><\/dl>

The Halo DB-20 is a high performance double beam spectrophotometer suitable for many analytical applications where a higher level of accuracy is required.<\/p>

Spectral Features
<\/strong>Coma aberration elimination from the concave diffraction grating achieves a high resolution 1.5nm (DB-20S : 1nm) spectral bandpass and certifies compliance of the Halo DB-20 to the stringent European Pharmacopoeia standards.\u00a0 Other specifications include an impressive wavelength accuracy of\u00a00.3nm, noise level 0.0003Abs (500nm) and stray light\u00a00.05% (220nm NaI, 340nm NaNO2).<\/p>

Built-in and Diverse Range of Measurement Modes
Photometry Mode:<\/strong>\u00a0Perform quantitative analyses in either absorbance or transmittance modes.\u00a0 Select from single wavelength, up to 6 different individual wavelengths, nucleic acid\/protein A260\/A280 ratios and set up calibration curves with up to 20 standards for concentration measurements.<\/p>

Time Scan:<\/strong>\u00a0Perform kinetic measurements for time periods ranging from 1 minute to >27 hours. Measurement intervals are factory preset and automatically selected when the scan time is set.<\/p>

Wavelength scan:<\/strong>\u00a0Perform a full spectral scan from 190 to 1,100nm at any of 8 incremental and preset selectable scan speeds starting from a high resolution 10nm\/minute up to a swift 3,600nm\/minute.\u00a0 Data is displayed as either numerical values or a graphical spectrum. Furthermore perform downstream processing of data, such as peak\/valley search or smoothing, directly on board or with the optional Halo UV Detective software.<\/p>

Dual Lamp Advantage
<\/strong>By virtue of the long life, halogen tungsten and deuterium lamps, the Halo DB-20s wavelength range is an extensive 190nm – 1,100nm.\u00a0 Besides, the dual lamp system results in higher accuracy than corresponding xenon lamps.\u00a0 Lamp switching is automatic and selectable from a wavelength range of 325nm to 370nm.<\/p>

User Friendly Operation and Information Rich LCD Display
<\/strong>The extra-large 190mm x 138mm, backlit LCD screen with adjustable brightness control displays a large array of data also in graphical format.\u00a0 The seamless and chemical resistant keypad is designed for easy and quick selection of navigation and function features whilst protecting against any laboratory spills.<\/p>

Validation Functions
<\/strong>To ensure optimum instrument performance, self-diagnosis incorporating a number of parameters and wavelength calibration are automatically initiated upon start-up.\u00a0 The Halo DB-20 is also equipped with a GLP\/GMP feature for analyses requiring validation and auditing. Parameters such as wavelength accuracy, wavelength reproducibility, bandpass, baseline flatness, baseline stability and noise level can be all validated and the audit report printed.<\/p>

Stand alone or PC Operation
<\/strong>The Halo DB-20 is fully equipped and capable of executing all functions in standalone mode. Simply connect a standard laser printer for direct printouts of data and graphs.\u00a0 For more advanced control, analyses and reporting, the simple slide of a switch places the Halo DB-20 under the direct control of the optional UV Detective software.<\/p>

On-Board Data Storage
<\/strong>Up to 20 operating programs and up to 10 sets of measurement data can be stored in the flash memory of the Halo DB-20. Programs can easily be recalled, edited and deleted.\u00a0 In standalone mode, data (in text format) can be downloaded directly to an external memory stick via the USB port and transferred for further processing to any computer loaded with commercial spreadsheets (such as Microsoft Excel)<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
