The design of a microgravity payload: the solution growth facility

Solution growth facility is a multiuser experimental equipment capable of automatically growing large single crystals from solutions; SGF accommodates an experiment for the measurement of SORET coefficient of some liquids which is the ratio of the thermal diffusion coefficient and the isothermal diffusion coefficient. SGF configuration employs four reactors filled with various solutions; three of them are operated in an isothermal temperature mode and the fourth reactor is designed for the study of separation of liquids with a temperature gradient. The facility incorporates data handling and control electronics based on the Z80 microprocessor
