1 The Liquid-Liquid Trough is deeper than a standard trough as this allows for the two liquid phases. The value in the brackets corresponds to confinement of the lower phase (other value for the upper phase).
2 The Alternate-Layer Deposition Trough is made of two separated compartments for creation of two monolayers simultaneously.
3 All trough tops labeled with the same frame name can be placed on the same frame, for modularity.
4 Need extension part for the serial port connections
