To provide an automatic analyzer in which a reaction container can be smoothly inserted into a hole of an incubator. An automatic analyzer 100 analyzing a sample includes: an incubator 105 having a hole 202 into which a reaction container 114 containing a mixture of the sample and a reagent is to be inserted; and a transfer unit 109 configured to transfer an unused reaction container 114 to the incubator 105 and insert the reaction container 114 into the hole 202. A lubricating member 203 having a self-lubricating property is provided at an inlet port of the hole 202.

A control method for an automatic analyzer that can improve robustness, throughput, and measurement accuracy. The automatic analyzer includes a sample loop connected between two sample ports of a plurality of sample ports of a switch valve. The method includes the steps of: adjusting a drive parameter of the syringe corresponding to a viscosity of the sample acquired in advance; switching the switch valve to a first state in which the sipper and the syringe contact with each other without through the sample loop; driving the syringe based on the drive parameter to draw and introduce the sample through the sipper; switching the switch valve to a second state in which the syringe and the sample loop conduct with each other; and driving the syringe based on the drive parameter to introduce the sample into the sample loop.

An object of the present invention is to provide an automatic analyzer capable of efficiently performing stiffing by a discharge operation. In the automatic analyzer according to the present invention, by lifting the probe while discharging a specimen or a reagent alter the probe starts to discharge the specimen to a vessel, as a height of a liquid level of the liquid in the vessel, which is discharged from the probe, is gradually raised, a distance between the liquid level in the vessel and a tip end of the probe is gradually increased.

Example automated storage modules for analyzer liquids are described herein. An example apparatus includes a refrigerated storage module having a plurality of shelves (to store a plurality of carriers) and a loading bay having an array of slots to receive one or more of the carriers. The loading bay is accessible by a user for manual loading or unloading of the carriers. The example apparatus includes a first carrier transporter coupled to the storage module to transfer the carriers between the shelves and a first transfer location and a second carrier transporter movable along a track connecting the storage module to an automated diagnostic analyzer. The second carrier transporter is to transfer a first carrier between the first transfer location and a slot in the loading bay and a second carrier between the first transfer location and a second transfer location accessible by the automated diagnostic analyzer.

A method for preparing for preparing a solution comprising a plurality of particles in a vial is disclosed. The method includes agitating the vial at a first predetermined mixing speed. The method also includes dispersing, into the vial, during the agitating, a first volume of buffer solution at a first predetermined dispensing rate to suspend the plurality of particles in the solution, wherein particles of the plurality of particles comprise a unique identifying feature.

A piercer washing port is provided at a position on the trajectory of a piercer differing from the sampling position. The piercer washing port is cylindrically shaped and has an opening for inserting the piercer in the upper surface and a washing space for housing the piercer inserted from the opening. Air injection ports for injecting air and washing liquid expelling ports for expelling water serving as a washing liquid are provided on the inside wall surface of the piercer washing port. The air injection ports are provided at four locations equally spaced on the periphery along the inside wall surface of the washing space. The washing liquid expelling ports 44 are provided at four locations equally spaced on the periphery along the inside wall surface of the washing space at different positions than those of the air injection ports.
