Equipment and Materials

Cooling samples of high‐temperature liquids. Sampling coolers (Fig. 1), designed for power stations, and those marine and industrial installations in which it is necessary to draw samples of liquids from vessels under conditions of high pressure and temperature, have been developed by Caird & Rayner Ltd., 777 Commercial Road, Limehouse, London, E.14.
