Abstract
Bubble-free injection of solution into a glass cell is necessary for appropriate crystal growth and in situ observation under the microgravity environment. The injection experiments under microgravity environment were performed with the parabolic flight using MU aircraft. The optimum requirements of inside coating patterns and the injecting speeds were found. In this paper, we discuss the influence of laminar-turbulent flow of injecting condition and the air-water interfacial shape of injecting into the glass cell on successful bubble-free injection.
