For precious samples and essential oils with large optical rotations, cells with only 0.02ml volumes and 10mm optical path lengths are available. Continuous Sampling Capability Access through gasketing in the top of the sample trough easily allows connection to a process stream. Readings can be downloaded via RS232 to a computer at fixed intervals or when prompted by an operator or a computer. Custom cells with special ferrels and fittings are available to allow connection to process streams. All Rudolph Research Analytical jacketed cells are available with quick release fittings which allow cells to be easily removed from the sample chamber.
Tubing is held in place by rubber gasketing on top of the trough and the door.
Temperature control is obtained through the use of an external water bath and a jacketed cell. Rapid Operation Rapid Operation is achieved by using a flow through polarimeter sample cell as seen in Figure 3. Once the sample cell is filled, each successive sample poured into the funnel will displace the previous sample through the drain tube. This method eliminates opening and closing the sample chamber door and interchanging sample cells. Measurements can be made about as rapidly as successive samples can be poured.
