The FlexiTemp™ Sampling Accessory is a new analytical tool for advanced temperature studies in the infrared spectral region. The easily accessible and relatively large sampling chamber is compatible with a variety of sample holders for liquids and solids enabling temperature studies and applications for biotechnology, material and coating performance and polymer industries. The FlexiTemp Sampling Accessory is available in Peltier (heating and cooling) and Resistance (heating) versions. The Peltier version for heating and cooling avoids the inconvenience and risks associated with liquid cooled accessories.
