A sample container cap (or “cap”) is configured to be used with a sample container for collecting fluids. The cap has a body and a shutter connected to the body. The cap has a (1) first, open position in which at least one body opening and at least one shutter opening are not aligned and the cap is configured so that fluid cannot readily pass therethrough, (2) second, open position in which the at least one body opening and the at least one shutter opening are aligned and the cap is configured so that fluid can pass therethrough, and (3) third, closed and locked position, in which the at least one shutter opening and the at least one body opening are not aligned and fluid cannot readily pass through the cap, and the cap is configured to not be moved to an open position.

The presently disclosed subject matter provides devices and methods for sample extraction from a swab during biological sample processing. In particular embodiments, the devices and methods are configured for use in conjunction with microfluidic devices for sample processing.

A specimen container holding apparatus is disclosed. The apparatus is configured to hold a container for receiving liquids from a bronchoscope. The apparatus includes a needle guide with a first and a second opening configured to receive a needle of the bronchoscope. The first and second opening may be disposed on a removable tip of the needle guide. The removable tip may be detachably connected to a removable tip connection point. The apparatus may further include a slide holder configured to hold a slide.

A specimen collection container is provided, the specimen collection container being capable of suppressing a change in a mixing ratio of a specimen collected to a liquid contained even when a long period of time has elapsed after manufacturing. A specimen collection container according to the present invention is a specimen collection container into which a specimen is collected, the specimen collection container including: a container main body having an opening; a plug attached to the opening; a barrier film disposed on an outer surface of the container main body; and a liquid contained in the container main body, the barrier film having a water vapor transmission rate at 40° C. and 90% RH of 0.8 g/(m.sup.2.Math.day) or less.

Provided herein is an integrated sampling and testing device, comprising a sampling device that comprises a syringe and specimen collector, and a testing device that comprises a cap, cylindrical container, and adaptor configured for sampling or testing.

A container cap liner that that facilitates the storage of gases and various volatile organic compounds (VOCs). More particularly, the container cap liner reduces the loss of gases and various volatile compounds thereby providing for relatively longer storage periods with relatively more accurate analytical analysis.

An exemplary blood sampling device can be provided that can collect a small amount of blood and prevent blood leakage. The exemplary blood sampling device can comprise a pipette tip-shaped blood sampler having an internal space for aspirating and holding blood by the capillary action and having openings at the top and bottom, a cylindrical container capable of accommodating the blood sampler and a cap piston-shaped sealing cap for sealing the container, wherein a receiving part is provided at the bottom of the container and a locking part and a screw part are provided on the upper outer side of the container, and a mandrel extending from the inner upper surface of the sealing cap is provided and a projection and a screw part are provided on the inner side surface of the sealing cap.

The present disclosure provides approaches for reducing tobacco-specific nitrosamines (TSNAs) in tobacco. Some of these approaches include genetically engineering tobacco plants to increase one or more antioxidants, increase oxygen radicle absorbance capacity (ORAC), or reduce nitrite. Also provided are methods and compositions for producing modified tobacco plants and tobacco products therefrom comprising reduced TSNAs.

A receptacle is designed for a chamber for an active substance. The receptacle includes two main elements. A first element is a transverse wall with a first main side facing an interior of the chamber, and a peripheral wall formed with the first main side of the transverse wall. A second element includes a bottom wall and a sheath extending from the bottom wall. The peripheral wall and the sheath surround one another and are in contact with each other so that the chamber is formed between the bottom wall, the transverse wall, the peripheral wall and/or the sheath. At least one ventilation groove is provided between the peripheral wall and the sheath form a ventilation channel connecting the chamber with the outside atmosphere.

A system for preparing a thrombin serum that can include a containment device, a cage received within the containment device, a cap attachable to the containment device, an inlet port configured to introduce a non-anti-coagulated autologous blood fluid into the containment device, and an outlet port. An activator, such as glass beads, can be present within the containment device.
