Excerpt from Chemistry for Photographers The construction of. A burette will readily be seen from the figure (fig. The instrument can be purchased with a_ glass tap, or with a glass jet, a piece of india-rubber tubing and a pinchcock, the latter being quite as convenient and much cheaper. For photographic purposes, burettes for the different developing solutions should be suspended round the sink as shown in the Sketch (fig. Being fed from stock bottles on a shelf above, when large quantities of material are used. It is well to have an opal glass plate at the back of the fixed burette, and to read the level of the bottom of the black curve at the top of the liquid when measuring. A float with a line engraved on it is sometimes used for reading, and has the advantage of keeping the solution from the air as well as or better than a Stopper. The construction of a pipette will be seen from the last part of figure 1. It is filled by drawing up the liquid with the mouth: the finger is then placed rapidly on the top, and the liquid is allowed to run down to the mark. The pipette with its contents is then transferred bodily to the vessel into which it is required to run the liquid.
