The Turret 6 is a 6-position cuvette changer for absorbance or fluorescence measurements. A secondary housing around the turret permits gas purging around the cuvettes and makes it ideal for use in circular dichroism spectrometers. A fiber optic version provides lenses and fiber optic connections, permitting its use as the core of a high-throughput spectrometer.
The CD 250, with its cuvette-driven architecture, is ideal for a variety of forms of spectroscopy: UV/Vis, fluorescence, and circular dichroism. The CD 250uses an exchangeable cuvette carriage, and can therefore accommodate a wide variety of cuvette styles, films, plates and other samples. It is thus ideal for circular dichroism measurements that often depend on the use of cylindrical, square or rectangular cells of various path lengths.
The qpod is a compact sample compartment with a temperature-controlled cuvette holder in the center. Four optical ports surround the cuvette holder and may be configured as needed with optics for many kinds of measurements. Use it for absorbance, fluorescence, or Raman spectroscopy, with or without the use of optical fibers.
The FLASH 300 is a stand-alone temperature-controlled cuvette holder that is generally mounted on an optical breadboard, surrounded by optical components. It has vertical and horizontal position adjustments. The normal temperature range of the FLASH 300 is -40 °C to +105 °C. An extended temperature option permits work from below -40 °C all the way up to +150 °C. An optional windowed jacket is available for work at low temperatures, isolating the cuvette from the environment.
The PAS 1010 is a complete system for pulsed-laser photoacoustics, without the laser. The core of the system is a FLASH 300 cuvette holder outfitted for use with an ultrasonic transducer, with the temperature stability and precision required for this form of spectroscopy. The PAS 1010 provides optics, energy probes, a fast diode trigger, cuvette holder, transducer, preamp, data acquisition hardware and a digitizing oscilloscope.
