A flying leads assembly includes a flying lead having an inner layer which forms a liquid passage and an outer layer which acts as a sacrificial layer in use, thereby allowing integrity of the passage to be maintained for a long period of time. A further layer is provided intermediate the inner and outer layers which can be used to provide support to the assembly. The flying lead assembly, or a number of assemblies, are then located in a guide with lubricant material.

A pipette tip includes a body and projections. In the body, a flow passage in which liquid from the syringe flows and an ejection opening that ejects the liquid, which has flowed through the flow passage, to the outside are formed. The ejection opening is formed in a distal end portion. The projections are provided on the distal end portion and protrude from a region around the ejection opening in the ejection direction of liquid. The projections are partially disposed around the central axis of the body. Even in a case where a residual droplet adheres to the ejection opening, the residual droplet does not adhere to an injection opening of a sample container, because the projections guard a region around the residual droplet.

A display screen 100 of an operation panel displays: a function (130) that gives notification of the performance of a periodic inspection of a cooling system; and an operation button 131 for starting inspection of the cooling system. During an easy inspection, a compressor 9a of the cooling system 9 is activated when a rotor 5 is not installed, it is determined whether the temperature detected by a temperature sensor 12 falls to a prescribed temperature (e.g., ?3? C.) within a prescribed period of time (e.g., within 10 minutes) from activation, and the cooling system is determined to be normal if the detected temperature falls to the prescribed temperature and abnormal if not. The results of the determination are stored at a storage unit of the centrifuge, the timing 132 of the next inspection is displayed on the display screen 100, and it is possible to reference a past inspection history.

The present invention relates to a method, a kit and an apparatus for pretreatment of bacterial test. More specifically, the present invention relates to a method, a kit, and an apparatus for continuously performing separation of blood cells and bacteria from a sample containing impurities such as blood cells, destruction of blood cells, and collection of bacteria.
