Abstract
THE form of pipette shown in Fig. 1 is useful for drawing up and delivering minute quantities of liquid. It can also be used for manipulating microscopic organisms, and in this respect seems to have some advantages over the one commonly used in biological class-work. The U-shape, by bringing the bulb near to the nozzle, gives a steadier grip, especially if the front part of the tube be enlarged. The U-shape also makes it possible to have an air-hole (A) for regulating the action of the bulb with the finger-tip. If the hole be well placed, it can be closed and opened with a minimum of jar. Pipettes of this form with the nozzle made of thermometer glass can be obtained from Messrs. Reynolds and Branson, Ltd., Leeds.
