Abstract: A sample assembly includes a vial, a vial insert, and a sealing arrangement. The vial insert could be any combination of a sample chamber, a matrix, or a swab breaker configured to be positioned within the vial. The sealing arrangement includes a coupling portion and a cap assembly. The coupling portion defines a mounting channel sized to receive a portion of the vial. The coupling portion is configured to slidably couple to the vial. The cap assembly includes a desiccant cap. The desiccant cap is configured to couple to the vial to selectively form a sterile barrier between the sealing arrangement and the vial.

Abstract: A sample kit includes a sealable container having a first region, a second region, and a third region. The first region is arranged to house at least one collection device. The second region is arranged to house at least one sample identification holders. The third region is configured to house a desiccant. The collection device is configured to obtain a sample, where the sample is configured to be positioned within the sample identification holder to define a completed sample. The sealable container includes a coating on at least one of an inner surface of the sealable container or an outer surface of the sealable container.

Abstract: Powdered starting material utilized for molding (e.g., rotational molding, injection molding, blow molding), extrusion, and the like can be preheated to reduce the time required to complete the processing of the material. After being preheated to a temperature below a melting temperature of the powder, the powder is transferred to a processing station. For example, in a rotational molding system, the preheated powder is transferred to a mold, where the preheated powder is melted and the mold is rotated such that the molten material adheres to the walls of the mold. After obtaining a desired distribution of the material over the walls of the mold, the temperature of the mold is decreased as rotation of the mold continues. When the article is sufficiently cooled, the article is removed from the mold.
