1. A container cleaning device which cleans a container for holding a sample, comprising:
an extended discharge member which comprises a body having a hollow tubular discharge flow path which connects to an aperture at an end of a bottom portion of the body, wherein the extended discharge member is insertable into a container having a substantially hemispherical shaped inner bottom, wherein:
the extended discharge member is shaped to guide liquid which flows along the extended discharge member to the aperture,the bottom portion of the extended discharge member is also substantially hemispherical shaped to enable the extended discharge member to be inserted close to the substantially hemispherical shaped inner bottom of the container,a plurality of engraved channels are radially extended out from the aperture, which extend upward along the bottom portion of the extended discharge member to help guide the liquid which flows down along the extended discharge member to the aperture; and a cleaning nozzle disposed adjacent to an upper portion of the extended discharge member to dispense a cleaning liquid into the container, wherein the dispensed cleaning liquid is guided to flow down along the extended discharge member to the aperture through the plurality of engraved channels.
