UV-VIS Spectrophotometer with Double Beam Double Monochromator UV1000

UV-VIS Spectrophotometer with Double Beam Double Monochromator UV1000

The UV1000 Spectrophotometer incorporates dual monochromator technology making it well suited to even the most demanding of applications in all areas of UV-Visible Spectroscopy including :

• Pharmaceutical * Material Science

• Metrological Verification * Biotechnology

• Food Safety - Research

Wireless instrument control and data acquisition can be achieved from a Tablet PC using Wi-Fi technology allowing the analyst to move freely around the laboratory whilst also keeping track of sample measurements.

The optical design of UV1000 offer extremely low stray light characteristics (0.0001%T NaI, 220 nm) which allows for an extensive photometric range (-6.0 – 6.0Abs). Measurements at deep ultra-violet wavelengths can also be

The instrument can be optically configured to suit the needs of the sample by means of a continually adjustable slit for precise control of spectral resolution and beam size adjustment by means of an attenuating wheel. Precise wavelength accuracy is ensured by the integrated Mercury Emissions Lamp used for automatic correction of spectral deviation. A whole host of specialised accessories are available to suit the specific requirement of the sample, these include
