The present application provides a child-resistant liquid dispensing closure apparatus, which includes a plunger and pipet, and preferably a dosage measuring system that is integrated that appears as the plunger is withdrawn from the pipet. The closure may be used for a bottle containing a liquid for oral administration of solutions, syrups, suspensions, elixirs, tinctures, concentrates, and the like.

A container for the heating of samples and a system comprising such a container and provides a container for processing samples, wherein the container is made of a material comprising electrically conductive particles.

Embodiments can provide a test tube vacuum retainer system, comprising an outer body comprising a midline plate; one or more side walls, a bottom wall, and a top plate comprising an access hole; a test tube holder comprising a sealant ring; a base; and a vacuum tube comprising an external outlet; wherein the test tube holder is secured within the outer body to the base, which in turn is secured to the midline plate; wherein the vacuum tube is connected to the test tube holder at a first end, and the external outlet is configured to be connected to a vacuum pump configured to apply a vacuum force to the test tube holder when a test tube is inserted into the access hole and placed onto the test tube holder.

Vial assemblies comprising a tubular body and a flexible bottom or flexible liner are described herein, wherein the flexible bottom or liner is configured to compress at least partially upon the application of force. Methods for storing and removing frozen samples from such vial assemblies are also described herein.

A cover for a fluid container having an essentially plane cover plate for closing at least one opening of at least one fluid container and at least two ports, and each port has a through channel extending through the entire thickness of the cover plate and a fluid impermeable first membrane is arranged over the entire cross section of the through channel of the first port and an at least gas permeable second membrane is arranged over the entire cross section of the through channel of the second port is disclosed.

Reagent devices including a liquid container and a reagent insert are provided. Aspects of the reagent insert include a first dried reagent composition and a second dried reagent composition distinctly positioned on one or more surfaces of a solid support. Also provided are methods of making and using the reagent device or reagent insert, as well as systems and kits including the same.

An apparatus for storing blood plasma separated after fractionation from whole blood within a wrapped hematocrit (capillary) tube. The apparatus is large enough to receive and display a standard laboratory identification label. The apparatus stores plasma from a hematocrit tube that does not include thixotropic gel. The apparatus housing has an intended upright orientation, a central axis, a top end, a bottom end, and side walls defining an internal cavity. A wall with an upper surface and a lower surface divides the internal cavity into an upper cavity and a lower cavity. A reservoir is formed in the upper cavity. A removable cap seals the reservoir. The cap is movable between open and closed positions. A channel within the lower cavity extends axially from the bottom of the housing to the wall. The channel receives and supports the wrapped hematocrit tube while plasma is expelled therefrom and into the reservoir.

The present invention features the application of a simple, inductively-coupled measurement system into the cap of standard laboratory sample tubes, thus enabling continuous, wireless ionic sensing of a bevy of samples. The system may be powered by a compact Class E amplifier using inductive coupling via a designed resonance frequency of 1 MHz. Other frequencies can be used, such as the popular near-field communication (NFC) frequency of 13.66 MHz. Signals are transmitted back via load modulation at frequencies a fraction of the power carrier frequency, thus allowing for extraction of the signal frequency. Results clearly show that modulation frequency tracks closely with open circuit potential, and the system features good sensitivity and linearity. This system holds promise for a host of applications.

An apparatus for temperature-controlling and thawing a temperature-controlled material which is arranged in at least one rigid container, including an openable housing containing a storage chamber for receiving the at least one container, and including a heating device containing a flat heating element which is operatively connected to the at least one container. A storage mat for receiving the at least one container is arranged between the flat heating element and the at least one container.

An article of manufacture for a reusable specimen transport tube rack cap that secures specimen collection swabs inside of transport tubes is disclosed. The reusable specimen transport tube rack cap includes a top surface connecting a plurality of specimen tube caps in a row, a bottom surface having a circular inner wall and a circular outer wall creating a specimen retention ridges defining a cap for each specimen tube, and access hole through each reusable specimen transport tube rack cap between the inner wall and the outer wall for providing access for a pipette into a specimen tube.
