  • Patent number: 11740019
    Abstract: Provided is a loading tray assembly for housing a lyophilization container and a related system and method. The loading tray assembly includes a chassis including a contact void configured to facilitate direct contact between the attached lyophilization container and a lyophilizer shelf. The method includes securing a multi-part lyophilization container including a peelable seal on a lyophilization loading tray assembly, inputting a liquid into a non-breathable section of the lyophilization container, loading the tray assembly into a lyophilizer, freezing the liquid, applying heat energy and a vacuum, the vacuum causing an opening of the peelable seal and occluding the lyophilization container to isolate the frozen liquid.

  • Publication number: 20210302452
    Abstract: A system is provided to automatically monitor and control the operation of a microfluidic device using machine learning technology. The system receives images of a channel of a microfluidic device collected by a camera during operation of the microfluidic device. Upon receiving an image, the system applies a classifier to the image to classify the operation of the microfluidic device as normal, in which no adjustment to the operation is needed, or as abnormal, in which an adjustment to the operation is needed. When an image is classified as normal, the system may make no adjustment to the microfluidic device. If, however, an image is classified as abnormal, the system may output an indication that the operation is abnormal, output an indication of a needed adjustment, or control the microfluidic device to make the needed adjustment.
