    Abstract: A mechanism for collecting a trace of a biological sample to be used for a biological sample analysis, and for preparing a diluted solution of the sample. A container for specimen preparation includes: a biological sample collecting device; and a container for sample dilution. The biological sample collecting device includes: a capillary tube having openings formed at both ends thereof; and a support member for supporting the capillary tube. The container for sample dilution includes: an opening; and a swirl flow generating member formed on an inner wall of the container for sample dilution. The capillary tube of the biological sample collecting device is arranged inside the container for sample dilution by the support member.

    Abstract: A gradient liquid feed device allows reduction in size of a high performance liquid chromatography type sample analyzer. The gradient liquid feed device includes a plurality of carrier liquid reservoir tanks configured to store carrier liquids of mutually different compositions, a plurality of single plunger pumps capable of drawing and discharging the carrier liquid from the plurality of carrier liquid reservoir tanks, a mixer configured to mix the carrier liquids discharged from the plurality of liquid feed pumps and feed the mixed carrier liquid, and a pulse damper in communication with the mixer and configured to absorb pulsation that may occur during liquid feeding. The single plunger pumps have a function for variably setting a length of stroke for drawing and discharging the carrier liquid and a function for variably setting a ratio between the carrier liquid drawing time and the carrier liquid discharge time.
