SPECTROPHOTOMETER

Double Monochromator UV-Visible Spectrophotometer

The Series Spectrophotometer incorporates dual monochromator technology making it well suited to even themost demanding of applications in all areas of UV-Visible Spectroscopy including: Pharmaceutical; Material Science; Metrological Verification; Biotechnology; Food Safety; Research.

The optical design of both the T110+  and  T112+ offer extremely low stray light characteristics (≤0.00004%TNaI,220 nm) which allows for an extensive photometricrange (-8.0 – 8.0Abs).

Measurements at deep ultra-violetwavelengths can also be achieved with use of Nitrogenpurged optics. 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:

  • Both 60mm and 150mm Integrating Sphere for Diffuse reflectance measurements.
  • Absolute, and Specula reflectance measurements accessories.
  • Polarizing Optics.
  • Thermostatic Cell Holders for temperature control.
  • Various long and short pathlength cell holders.
  • Automated cell changers for both sample and reference beams.
  • Tablet dissolution accessory for pharmaceutical quality control
