Schematic diagram of the acrylic swim channel with the quartz crystal (yellow) held in place with rubber gasket (red). The measurement sequence starts with buffer introduced into the swim cell (a). The semen sample is introduced at the opposite end of the swim channel to the quartz crystal (b). The sperm swim down the swim channel (c) and attached to the quartz crystal causing a frequency change (d).
