摘要:
A method for collecting and delivering biological samples to a destination, such as an analyzer are provided herein. In one example, a plurality of samples, each including particles, is obtained from respective wells of a sample source having a plurality of wells. The plurality of samples are introduced into a fluid flow stream contained within a conduit having an inner diameter and in communication with a destination. An inner surface of the conduit is coated with a hydrogel barrier substance, such as poly-HEMA. The fluid flow stream is guided through the conduit to a destination. In one example, the destination may be a flow cytometer. Methods of preparing a poly-HEMA solution and coating the inner surface of a conduit with poly-HEMA are also provided.

A controlled environment enclosure comprises a robotic arm manipulation system used to protect and unprotect a fluid path and a swab within the controlled environment enclosure. The apparatus allows the fluid path to be protected against dangerous decontamination vapors and chemicals before the controlled environment enclosure is decontaminated. The apparatus allows the fluid path to be unprotected without the use of gloves or other means that degrade the integrity of the controlled environment enclosure when decontamination is completed. The apparatus and method allow for the protecting, unprotecting and decontaminating sequences to be automated. In some embodiments the fluid path comprises a fill needle that can removably and aseptically be sealed with a disposable monolithic injection moulded polymeric fill needle sheath. The apparatus and method further allow for the use of a swab disposed in a swab holder that is aseptically and removably sealable to a swab cap to protect the swab against decontamination vapors.

An injector capable of preventing contaminants from being mixed in a chemical liquid when sucking and discharging the chemical liquid and a chemical liquid preparation apparatus having the injector. The injector (1) comprises an injector body (11) having a cylinder (2) capable of reserving the chemical liquid, a piston (3) held in the cylinder (2), a ball screw (4) formed at the end part of the piston (3), and a drive motor (5) as a drive means for rotating the ball screw (4) and a duct (6) surrounding the injector body (11). The duct (6) comprises at tip part (6b) formed so that the cross sectional area of the inner peripheral surface thereof can be gradually reduced toward the tip side of the cylinder (2). A plurality of holes (6a, 6c) circumferentially tilted relative to the axial direction of the piston (3) are formed in the wall of the duct (6). An axial fan (7) as a suction means for sucking the contaminants is installed in the duct (6), and when the axial fan (7) is driven, an upward air flow occurs in the duct (6) and dust in the air present in the duct (6), abrasion powder of steel balls (4c) produced from the ball screw (4), and contaminants such as spattered lubricating oil are sucked to the upper part of the duct (6).

Disclosed are a liquid cover slip for protecting tissue slices and improving resolution, a composition for making the liquid cover slip, a slide structure having the cover slip and its manufacturing method. The slide structure includes a support layer, a tissue slice seated on an upper center of the support layer, and a liquid cover slip formed to surround an exposed surface of the tissue slice completely and made of a polyvinyl pyrrolidone polymer having a molecular weight of 10,000 to 360,000 as a main component. Thus, optical resolution is improved to enable micro observation of a tissue slice and precise selection of a micro region. In addition, the tissue slice keeps a non-aqueous state to be isolated from the air, so macromolecules in the tissue slice are not destructed or denatured.

A method for determining not to reuse a previously used and cleaned reaction cuvette in an analyzer when an assay scheduled to be performed may be adversely affected by contaminants remaining in the cleaned reaction cuvette. If determined not to reuse a previously used and cleaned reaction cuvette, the previously used and cleaned reaction cuvette is replaced with an unused new reaction cuvette.

The present invention relates to a cartridge for receiving a sample, comprising a housing, a lid capable of hermetically closing the housing and a tampered-proof system, coupled to the cartridge, to indicate to a user whether the lid has been removed from the housing, thereby allowing the user to determine if the sample has been potentially contaminated. The present invention also relates to an apparatus for storing samples, the apparatus comprising a housing, a sample receiving means provided inside the housing a sample handling device for automatically inserting and removing the samples from the sample receiving means and a user interface coupled to a control unit for controlling the sample handling device. The present invention also relates to an apparatus for automatically sampling a sample.

This device is directed at filling multiple receptacles (51) without losing integrity of the system. It is also directed at receiving a sealed container of receptacles opened or stopper/closed, opening an access into the sealed container, retrieving receptacles (51), filling those receptacles (51), stoppering the receptacles after filling and ejecting the receptacles, either directly into the outside environment or into a closable sack or container, in the latter case while maintaining the integrity of the environment within the device and, if desirable, the sack or closed container.
