Abstract
A Langmuir-Blodgett (LB) film forming apparatus has a packing unit for orientating and packing a sample which is a composition for forming a monomolecular film developed on a subphase stored in a first tank, a sampling unit for sampling the orientated and packed monomolecular film on a substrate, and an outer casing enclosing the packing unit and sampling unit. The packing unit has a second tank in which a circulating solution is stored and the first tank is disposed in the solution. A temperature of the circulating solution in the second tank is controlled by a first controller and a temperature of atmosphere enclosed by the casing is controlled by a second controller. The first and second controllers are synchronously operated. The substrate is disposed above the subphase in a vertical attitude. The sampling unit includes a pressure detector for detecting a pressure of the packed monomolecular film and the packing unit includes a barrier driving means which is operatively connected to the pressure detector so that the movement of the barrier stops when a detected pressure reaches a predetermined value.
