Abstract
A syringe is depressurized to suck a slight amount of air into the tip portion of a probe of a probe assembly, forming an air layer. Then, the syringe is depressurized again to suck into the probe assembly a sample to be discharged into a reaction container. Accordingly, the target sample to be discharged, the air layer and extruding water are placed into the probe assembly in the named order from the tip portion of the probe.
Claims5
A sample distributing method comprising the steps of:
- mounting a probe having an open tip portion on a mounting member;
- sucking a predetermined sample into said probe through said open tip portion thereof;
- discharging said sample from said probe through said open tip portion thereof to a discharging position;
- detaching said probe from said mounting member;
- and
- introducing, before said sucking step, an effective amount of a pressure transmission liquid into said probe and retaining said pressure transmission liquid in said probe so that a quantity of air is removed from an interior portion of said probe, and wherein:
- said sucking step comprises sucking each of a plurality of different samples, each having a different known viscosity, separately into said probe;
- said sucking step and said discharging steps are respectively controlled by applying different pressures to said pressure transmission liquid, based on the viscosity of each of said plurality of different samples;
- and
- said discharging step comprises separately discharging each of said plurality of different samples from said probe.
