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.

Optical density instrument and systems and methods using the same

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.
