Disclosed is a solid-liquid separation method including: sucking a suspension containing particles, through an opening formed at a leading end of a suction nozzle, into the suction nozzle; allowing at least a part of the particles contained in the sucked suspension, to sediment to be clogged in the suction nozzle; and ejecting a liquid inside the suction nozzle, through the opening of the suction nozzle clogged with the particles.

Aspects of the present disclosure relate to methods and devices for automatically transferring samples and/or reagents from sample vessels and/or reagent vessels into at least one receiving vessel In one example embodiment, a pipetting device is disclosed including a pipettor that is movable along a first direction and has at least one first pipetting needle that is movable along an arm of the pipettor along a second direction, substantially normal to the first direction. The pipetting needle is lowerable along a third direction into the individual vessels. In some specific embodiments, the arm of the movable pipettor has at least one second pipetting needle which, regardless of the current position of the first pipetting needle, is movable past the first pipetting needle and is lowerable into the individual vessels.

The present invention relates to a method and a system (400) for filling a closed container (200) with a fixative solution. The system comprises a container (200) comprising a container body (230) for receiving a biological specimen, a lid (220) for selectively closing the container body (230) and a port (100) forming a unidirectional barrier in a direction from the inside (IC) to the outside (OC) of the closed container (200). The system further comprises a dispensing apparatus (500) having a filling nozzle (300) for dispensing the fixative solution. The filling nozzle (300) is relatively moveable with respect to the container (200) between a retracted position and a filling position to fill the container (200) with the fixative solution.

A support that comprises a plate having a first side and a second side opposed to the first side. The plate has a sample section including bottle-receiving members defined in the first side and configured for holding the bottles in a fixed position relative to the plate, and first conduit-receiving openings extending from the first side to the second side for receiving conduits extending from the bottles. The plate has a manifold section including second conduit-receiving openings extending from the first side to the second side for receiving the conduits. The plate has a channel section including channels defined in the second side and extending between the first conduit-receiving openings and the second conduit-receiving openings for receiving the conduits therein. The support may be used for example on a shaker. A method for retaining bottles and conduits connected to the bottles is also discussed.

Devices for magnetic 3d culture are described including magnetic lids/bases for single Petri plates, adjustable height cap for same, as well similar devices for multi-magnet culture plates. A pen-like device for sterilely lifting and moving cells is also described, and this magnetic pipettor can also exist in multi-well magnetic pipettor formats.

A material for manipulating liquid volumes includes a porous substrate having first and second surfaces; and a liquid-manipulating pattern disposed on the first surface, the pattern having a first reservoir connected to a target point via a first wedge-shaped transport element to enable liquid transport from the target point to the first reservoir regardless of gravity, wherein the first surface is one of hydrophobic or superhydrophobic, and wherein the first wedge-shaped transport element is one of superhydrophilic when the first surface is hydrophobic, superhydrophilic when the first surface is superhydrophobic, and hydrophilic when the first surface is superhydrophobic. The pattern can include a second reservoir connected to the target point via a second wedge-shaped transport element to enable liquid transport from the target point to the second reservoir regardless of gravity.

An automatic analysis device that avoids carryover and prevents deterioration of analysis performance without controlling reaction cell position is provided with: a reaction cell in which a sample and a reagent are mixed and allowed to react; a light source that radiates light onto the mixed liquid of the sample and the reagent; a detector that detects the light radiated from the light source; and a cleaning mechanism that cleans the reaction cell. The cleaning mechanism includes an intake nozzle that draws in liquid from the reaction cell and a discharge nozzle that discharges the liquid into the reaction cell; the intake nozzle and the discharge nozzle can move vertically; and the intake nozzle is cleaned by lowering the intake nozzle into the reaction cell, in which a cleaning liquid or cleaning water have been accumulated, without drawing in the cleaning liquid or the cleaning water.

The present invention relates to a biological material extraction apparatus. According to the present invention, a tube in which a solution for use in extracting a biological material is contained is rotated to directly mix the solution, and cells where stirring is being conducted in each step are sealed to fundamentally block stirring-induced pollution between cells, thereby improving an extraction efficiency.
