Plate

Abstract

To provide a plate with which, although the plate has a plurality of microchannels or a microchannel in which a plurality of branch channels are formed, when a sample flowing through a microchannel is observed by a microscope, it is possible to easily identify the position of the microchannel or the branch channel under observation without reducing the magnification of the microscope. A plate having a microchannel therein includes an identification mark for identifying a position of the microchannel in a plane direction of the plate. When the microchannel includes a plurality of mutually independent microchannels, the identification mark is preferably formed for each microchannel. When the microchannel includes a source channel communicating with an injection port through which a sample is injected and a plurality of branch channels communicating with the source channel, the identification mark is preferably formed for each of the source channel and the branch channels.
