The chamber is shown in Fig. 5, A. For centrifuging in tubes the rotor 3 shown in Fig. 1 is most con- venient. This rotor can be made of solid steel rod 1% inch diameter, turned to shape, with two crossed grooves to hold centrifuge tubes milled in the upper surface. A cover of duraluminum fits over the grooves and is held in place by a machine screw. For low speeds the tubes can be made of thick-walled Pyrex tubing, but for high speed they are best made of duraluminum or aluminum, which are light and do not easily corrode. Holes are bored in square duraluminum rod Mic. M, FIG. 4.

Only ordinary precautions are necessary to make tubes of the same weight, since the rotor assumes its own position of equi- librium when revolving and a considerable amount of unbalance does not interfere with the stability of the rotor, provided the supporting 3 Constructed by Mr. P.
