    Abstract: To prevent a pulsating flow in a column used for the liquid chromatograph, a flat liquid transferring chamber (6) provided in pressure vessels (1a, 1b) is partitioned by diaphragms (2a, 2b) on both flat sides thereof, and sealed compression chambers (5a, 5b) filled with a compressible substance are disposed facing the diaphragms.

    Abstract: In a detection apparatus, a linearly polarized light beam polarized in a polarizer (62) is converted by being transmitted through a Pockels cell (60), driven by an alternative voltage, into an alternative linearly polarized light beam and a circularly polarized light beam, which is transmitted through a sample solution flowing through a flow cell (68). The transmitted light beam is separated into two polarized light components, and an intensity thereof is measured to obtain a signal proportional to an angle of rotation by the sample solution. A signal corresponding to an angle of rotation caused by an optical rotary power of the sample solution is obtained by subtracting the signal obtained during irradiation of the circularly polarized light from the signal obtained during irradiation of the linearly polarized light. The sample solution (18) is infused into an optical path of the flow cell (68) under a condition where mean velocity is 0.5 to 5 m/sec.

    Abstract: A culture device to apply uniform stress to cells is proposed. A culture device is formed in a rectangular box shape from a deformable material, comprising a bottom membrane and side walls upstanding from the entire periphery of said bottom membrane, wherein an engaging member is formed in opposing side walls on a line extended from a peripheral edge of said bottom membrane. By providing the latching member in the culture membrane so as to latch the cells to the latching member, the slippage between the bottom membrane and sample cells is forestalled upon the extension of the culture membrane.
