Provided herein are an optical test platform and corresponding method of manufacturing the same. The test platform may include a shell defining a cavity for receiving a sample tube, a first aperture, and a second aperture. The first aperture and the second aperture of the shell may each be configured to optically couple the cavity with an exterior of the shell. The test platform may further include a first window and a second window embedded in the shell. The first window may seal a first aperture and the second window may seal a second aperture. The first window and second window may each permit the optical coupling of the cavity with the exterior of the shell. The first window and the second window may be optically coupled via the cavity, and the shell may prohibit optical coupling between the first window and the second window through the shell.

Optical test platform

Instruments, systems, and methods for measuring optical density of microbiological samples are provided. In particular, optical density instruments providing improved safety, efficiency, comfort, and convenience are provided. Such optical density instruments include a handheld portion and a base station. The optical density instruments may be used in systems and methods for measuring optical density of biological samples.

Apparatuses and associated methods of manufacturing are described that provide a tip resistant optical testing instrument configured to rest on a surface. The optical testing instrument includes a shell defining a cavity for receiving a sample tube. The shell includes a bottom shell surface, wherein the bottom shell surface defines at least one support element, wherein the at least one support element is configured to engage the surface to support the optical testing instrument in a testing position, and a translational surface configured to engage the surface to support the optical testing instrument in an angled position. In an instance in which the optical testing instrument tilts from the testing position to the angled position, the translational surface is configured to engage the surface contacting the translational surface to prevent the optical testing instrument from tipping further and allow the optical testing instrument to return to the testing position.

An incubation station has a carousel for receiving a plurality of test sample cards. An even temperature and air flow distribution inside the carousel and incubation of the cards over time at the proper temperature was found to be critically dependent upon air flow characteristics within the incubation station. To optimize air flow, the carousel was given an open rear side that is exposed to an air distribution table having a cover plate placed adjacent to the rear surface of the carousel. The cover plate has a plurality of elongate slots positioned in a symmetrical ring-shaped pattern in registry with the carousel. The elongate slots are positioned at an angle relative to the slots in the carousel such that each carousel slot receives air from more than one slot. An extra fan was also added to the system to increase the flow of air into the air table. Scallop features on the carousel walls also promote even distribution of air flow over the cards. The carousel may be divided into a plurality of carousel segments to increase ease of removal and insertion of the carousel into the incubation station and manufacturability of the carousel.
