qpod 2e/ABSKIT (discontinued)

qpod 2e Absorbance Kit: temperature-controlled sample compartment with internal temperature controller and lenses for absorbance
Product Overview

The qpod 2e/ABS kit combines the qpod sample compartment with a pair of collimating lenses, an optimal system for using fiber optics to measure the absorbance of a temperature-controlled solution. The qpod 2e is a roughly square box about 120 mm on a side and 90 mm high. In the center is a temperature-controlled tower with optical ports on each of four sides and slit holders to control optical access. Each of the four sides of the qpod has a mounting ring for optical components, thermally stable and precisely aligned with the tower. Attach fiber optic cables to the lens systems and screw them in place on opposite sides of the qpod. Illuminate through one cable and a collimated beam about 5 mm in diameter will pass through the cuvette and focus onto the collection fiber. A dry gas purge of the compartment enables easy use at low temperatures down to -30 °C. The standard qpod readily achieves a high temperature of +110 °C. Operate the qpod 2e on a lab bench or build it into your own full spectroscopy system. The qpod is frequently used with fiber optic options available with commercial spectrophotometers. For computer control, use program Q-Blue, provided at no charge, or write your own program utilizing simple text commands for control.
