Solvent evaporation rates in the closed capillary vapor diffusion method of protein crystal growth

The rate of transport of water vapor from the evaporator end to the condenser end through the intervening air space in closed protein crystal growth capillaries of the Plaas-Link design has been analyzed both theoretically and experimentally. The theory is based upon the assumptions that (1) the concentration of the precipitating agent exceeds that of all other solutes and (2) the process determining the rate of approach to equilibrium is the...
