All Glass CCD According to Craig

Several glass units, allowing mixing, settling and phase transfers (Figure 4) are arranged in batteries on a horizontal axis. Movement about this axis can be used to gently mix the phases, to put the glass units in position for settling of the phases and for decanting the upper phases, respectively. The times for each part of the CCD cycle as well as the number of transfers can be programmed. Standard types of such machines allow 50 transfers while more advanced machines may be used for up to 1000 transfers. The glass units can be obtained in various sizes but standard tubes have space for c. 2 mL (fixed amount) of lower phase and up to 5 mL of upper phase.
