A biological fluids concentration device, including a tube-in-tube assembly, is disclosed. The tube-in-tube assembly receives biologic fluids and may then be placed in the bucket of a centrifuge and spun to separate out the components of the biological fluid by their various densities. For example, whole blood may be centrifuged in the tube-in-tube assembly for separating into plasma, red blood cell component, and a buffy coat. A piston slideably and sealingly engages an inner tube of the tube-in-tube assembly, the inner tube fitting within an outer tube. A lid is designed to engage the top of the outer tube, which lid has an opening therein for receipt of a plunger. The plunger is adapted to move up and down with respect to the lid and the tubes, so as to sealingly, in a down position, and unsealingly, in an open position, engage the top of the inner tube of the tube-in-tube assembly.

This container storing a washing solution for a blood analyzer includes a container body made of thermoplastic resin resistant against a chlorine-based washing solution and provided with an opening on an upper portion, a chlorine-based washing solution stored in the container body, and a multilayer film covering the opening. The multilayer film includes a seal layer heat-sealed to the container body thereby blocking the opening and a gas barrier layer arranged on the outer side of the seal layer.

[Problem to be solved] A sample storage tube having the seal function to the tube body is provided by integral molding and the airtightness is secured in the sample storage tube.

[Solution] The sample storage tube 100 comprise a first molded portion 210 and a second molded portion 220 by the integral molding. The first molded portion 210 is molded as the base figure of the tube body. The second molded portion 220 includes at least the opening edge portion which contacts the lid 300 and closes the opening. The first molded portion 210 is molded by the first material such as polypropylene, the second molded portion 220 is molded by the second material such as TPE which is suitable for the seal object to secure the airtightness between the opening and the lid 300. This second molded portion providing the seal function is molded onto the opening edge of the tube body by the integral molding. The second molded portion 220 can be molded as a consecutive object from the bottom portion to the opening edge of the tube body.

A specimen collection, storage, transport, and testing device can include an outer vessel containing an internal cup having an openable drain having a brim raised above the bottom floor of the cup. Once opened the drain allows a portion of liquid specimen to flow from the cup into a lower chamber of the vessel containing a number of chromatographic assay strips. A lid sealing the vessel can include a downwardly projecting guide tube having first barrier sealing a bottom aperture. An oblong initiator can axially engage the guide tube, break the first barrier and open the drain to initiate the test while retaining a pool of liquid specimen in the cup for subsequent confirmatory testing.

The present disclosure provides an anti-pollution consumable and a method for Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) molecular diagnosis using the same, belonging to the technical field of nucleic acid detection and molecular diagnostics. The anti-pollution consumable includes an outer reaction tube, a sleeve and an inner reaction tube, where the inner reaction tube includes a second hollow cylindrical upper body and a second-type conical lower body sequentially from top to bottom; a top end of the second hollow cylindrical upper body is externally connected with a fixing ring perpendicular to the second hollow cylindrical upper body; a number of drain holes are provided at a bottom of the second-type conical lower body; the drain hole has a diameter of 0.01-0.8 mm; the drain hole is used for hydrophobic treatment; and the inner reaction tube is fixed inside the outer reaction tube through the sleeve.

An instrument system for acid digestion is disclosed. The instrument includes a heating block, a reaction vessel formed of a polymer that is resistant to acid and other chemical attack at temperatures above 150° C. and that has a structure (thickness, etc.) sufficient to withstand pressures above atmospheric, a metal sleeve surrounding the polymeric reaction vessel, and an opening in the block that has a cross-section corresponding to the cross-section of the metal sleeve.

There is provided a biological specimen separation instrument with which a biological specimen can be stably separated into a predetermined component. The biological specimen separation instrument includes an accommodation instrument (1) for accommodating a collected biological specimen, a filter (128) for filtering a predetermined component in the collected biological specimen, and a holding instrument (100) for accommodating the predetermined component filtered by the filter (128), where the holding instrument (100) is configured to be inserted into the accommodation instrument (1), in which the filter (128) is provided on a tip side of the holding instrument (100) in a direction of insertion into the accommodation instrument (1), a sealing member (130) is provided in an outer circumference on the tip side of the holding instrument (100) in the direction of insertion to allow movement in the accommodation instrument (1), in a state of being liquid-tightly brought into contact with an interior wall of the accommodation instrument (1), and the sealing member (130) has a Shore A hardness of 20 or more and 90 or less and has a residual siloxane concentration of 1 wt % or less.

The microfluidic device of the present invention includes a plate having a first main surface that has an opening area in which a plurality of openings for injecting fluid are formed, a second main surface being the opposite side of the first main surface, and an outer side surface communicating the first main surface and the second main surface; and a reservoir that has an opening with a bottom and is capable of storing liquid, the opening standing above the first main surface outside the opening area.
