Sample contamination is suppressed by strengthening the air barrier of a work opening portion. A safety cabinet includes: a work room; a front surface door covering a part of a front opening portion of the work room; and a work opening portion on a lower side of the front surface door allowing a worker to work with his or her hand in. An intake port suctions air in the work room and outside air through the work opening portion on a front surface side of a workbench in a lower portion of the work room. A straightening plate drawing an air flow and a linear light source are provided on the work room side of the front surface door and above a front portion of the work room.

Provided herein are methods for processing and/or detecting a sample. A method can comprise providing a barrier between a first region and a second region, wherein the first region comprises the sample, wherein the barrier maintains the first region at a first atmosphere that is different than a second atmosphere of the second region, wherein a portion of the barrier comprises a fluid in coherent motion; and using a detector at least partially contained in the first region to detect one or more signals from the sample while the first region is maintained at the first atmosphere that is different than the second atmosphere of the second region. The portion of the barrier comprising fluid may have a pressure lower than the first atmosphere, the second atmosphere, or both.

A thermo-gravimetric analysis system includes a chamber having an interior; and a sample crucible connected to and inside of the chamber, the sample crucible configured to hold a sample material. The system further includes a reference crucible connected to and inside of the chamber; and a metal organic framework (MOF) crucible connected to and inside of the chamber, separate from the sample crucible, the MOF crucible including an MOF material.

The present invention relates to a device adapted to facilitate transport of a biopsy sample from a sterile extraction site to laboratory-type equipment by which the biopsy sample is processed, while maintaining the biopsy sample wetted and sterile and automatically transferring the biopsy sample from the device to the laboratory-type equipment.

Clean chamber technology for 3D printers and bioprinters is described. An airtight chamber or enclosure is provided so that positive pressure can be created inside the chamber. Unfiltered air is sucked in from outside into the chamber through a high efficiency filter such as a HEPA filter, using an electrically powered fan or blower, filtering out at least about 99% of particles and contaminants. The filtered air is then pushed into a 3D printing area inside the chamber and out through vents within the frame of the chamber. The technology provides a clean environment for 3D bioprinting of human tissue models and organs and 3D cell culturing without requiring clean room facilities.

The invention provides a system for preventing fluid exchange between the interior and exterior of containment enclosures such as process-, hazard-, and research-enclosure systems generally, gloveboxes, containment systems, isolation systems, confinement systems, cleanrooms, negative air systems, and positive air system areas while simultaneously providing material transfer into and out of the enclosures. The invention also provides a method for transporting material into or out of a containment structure.

A door device for connecting a container having a container flange with a plurality of radial flanges distributed around its circumference to an isolation chamber includes a door reversibly movable from a closed position, in which it closes a passage opening of the door device, to an open position, in which it uncovers the passage opening, and an interface of a closure, in particular a first bayonet closure for fastening a lid attached to the container. The device further includes a frame having axial grooves for receiving the radial flanges of the container and a cover reversibly movable from an insertion position in which it releases the axial grooves for insertion and withdrawal of the radial flanges to a locking position in which it locks the axial grooves against withdrawal of the radial flanges to lock the container to the door device.
