External pressure type micro kit

External pressure type micro kit
Enables easy generation of monodisperse emulsion.
Ultra-small membrane emulsification device using SPG

System flow
System flow


This device is an emulsifying system in which the outside of tube-shaped SPG membrane (having 10mm effective length) is filled with dispersed phase liquid, and the inside, with continuous phase liquid; then pressure (external pressure) is given from outside to inside of SPG membrane by use of nitrogen gas while stirring the continuous phase liquid with a rotator. This external pressure system is basically the same as that of the mini kit, wherein the emulsifying pressure can be increased up to 500kPa at maximum. Therefore, for SPG membrane used in this system, the diameter of pore can be selected from a wide range down to sub micron including the working range (2 to 3㎛ or more) of internal pressure type micro kit.
