Water is circulated from an external circulating water bath (not included) through an internal passage in the cell holder which keeps the temperature of the sample uniform.
The four-position cell holder accommodates four square, 10 mm pathlength cells or four microcells with four adapters, P/N L2250139. When you occasionally work with limited volume samples, use the Microcell Adapter for the 5 mm pathlength microcells, which require a minimum volume of only 600 microliters. Includes six stirrer fleas, P/N 04978499.
