Temperature
Thermoelectric temperature control maintains the sample to a precision of ±0.02 °C within a range of
-40.00 °C to +85.00 °C. Depending on the humidity and ambient temperature (with dry gas purge) the
CUV-TLC-50F will operate down to about -10 °C without the formation of frost on the optical
components. Below this temperature, the CUV-TLC-50F requires additional insulation. We recommend
that the sample holder be carefully wrapped in bubble wrap or similar packing materials. Such materials
are inexpensive and function well. Very low temperature operation (down to -40 °C) requires the use of
precooled circulating water of a temperature within about 25 degrees of the target temperature. It will also
operate safely between 80 °C and 85 °C, although such high temperatures may adversely effect the
lifetime of the thermoelectric device. Temperatures of the sample holder are reproducible within
±0.03 °C. Reproducibility represents the temperature range, expressed as ± one standard deviation, over
which the temperature of the cuvette holder may vary from hour-to-hour or day-to-day as measured by a
NIST-traceable thermometer. Calibration data is provided with each sample holder. For experiments in
which knowledge of the exact sample temperature is critical, independent verification is required.
