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
