Solution separating apparatus.

摘要

The present invention relates to a solution separating apparatus having a container holding portion (21), a container pressurizing portion (22), an interface detecting portion (25), and a control unit. The interface detecting portion comprises a light emitting apparatus (121) disposed to one side and a light receiving apparatus (122) disposed to the other side of a parent bag (2a) held by the container holding portion sandwiched therebetween. The light emitting element comprises a plurality of light emitting elements disposed in a linear array, its length being positioned vertically, in order to allow the detection of the vertical displacement of the solution interface. In addition the present invention relates to a solution separating apparatus having a container holding portion, four tube clampers (36, 37, 38, 39) a container pressurizing portion, and a control unit. A weight measuring portion commonly consisting of two or more container holding portions (101, 102) can selectively measure the quantity of weight change of each container held by the container holding portion.
