Abstract:
A supernatant liquid collector with a balance weight forming function comprising: a first syringe in which a liquid to be separated into a primary supernatant liquid and a primary sediment liquid by sedimentation is accumulated; a second syringe in which a liquid with a specific gravity equal to that of the primary supernatant liquid is accumulated; a first treatment container which receives the primary supernatant liquid discharged from the first syringe; a first balance container which receives the liquid discharged from the second syringe; and a pushing member which pushes plungers of the first and second syringes at the same time,the pushing member pushes the plunger of the first syringe and thereby discharges the primer supernatant liquid in the first syringe into the first treatment container while pushing the plunger of the second syringe and thereby discharges the liquid in the same amount as the primary supernatant liquid discharged into the first treatment container from the second syringe into the first balance container.
