Pluggable Female Coupling

Each of our polarimetry cells is individually tested with respect to its pathlength. The actual pathlength of each cell is engraved on the cell to the nearest 0.001 cm (i.e. to the nearest 0.01 mm), together with the serial number of the cell. Cells are designed for easy lling and emptying. They are jacketed for thermostatting with constant temperature water, except for one owcell. Their residual cell rotation is almost zero and may be neglected in most measurements.
