Abstract
In a pre-processing system, a state in which a sample dispensing probe 20a and a syringe pump 81 communicate with each other through a channel 91 and a state in which the sample dispensing probe 20a and a culture tank 301 communicate with each other through the channels 91, 93, and 94 can be switched by operation of the three-way valves 82 and 83. For this reason, the liquid sample in the culture tank 301 can be automatically discharged from the sample dispensing probe 20a without requiring the user to directly sample the liquid sample. As a result, in the pre-processing system, the user's manual sampling work can be omitted, and the user's work can be simplified.
Claims5
1-6. (canceled)
A pre-processing system for performing pre-processing for a liquid sample from a liquid sample storage unit, the pre-processing system comprising:
- a sample setting unit in which a sample container is installed;
- a probe configured to suck a liquid sample from an inside of a sample container installed in the sample setting unit and discharge the liquid sample to a dispensing position;
- a pump driven when the probe sucks and discharges a liquid sample;
- a switching unit configured to switch to a state in which the probe communicates with the pump or a state in which the probe communicates with the liquid sample storage unit;
- and
- a cleaning solution storage unit configured to store a cleaning solution, wherein
- the switching unit switches to a state in which the probe communicates with the pump, a state in which the probe communicates with the liquid sample storage unit, or a state in which the probe communicates with the cleaning solution storage unit, and
- the liquid sample storage unit is a culture medium storage unit provided in a cell culture apparatus,
- the pre-processing system further comprising a tube pump provided in a channel between the switching unit and the culture medium storage unit, and is configured to be driven when a liquid sample in the culture medium storage unit is sent out to the probe.
