Contamination detection systems, kits, and techniques are described for testing surfaces for the presence of hazardous contaminants, while minimizing user exposure to these contaminants. Even trace amounts of contaminants can be detected. A collection kit provides a swab that is simple to use, easy to hold and grip, allows the user to swab large areas of a surface, and keeps the user's hands away from the surface being tested. The kit also provides open and closed fluid transfer mechanism to transfer the collected fluid to a detection device while minimizing user exposure to hazardous contaminants in the collected fluid. Contamination detection kits can rapidly collect and detect hazardous drugs, including trace amounts of antineoplastic agents, in healthcare settings at the site of contamination.

An apparatus including a sensor configured to sense total pressure within an inner chamber of a housing, and to sense differential pressure between the inner chamber of the housing and work area outside of the housing; a computer processor configured to receive signals from the sensor based on the total pressure and the differential pressure; and wherein the computer processor controls the rate at which the flapper oscillates based on the total pressure signal from the sensor, to thereby control the direction of flow of air from the inner chamber of the housing through the plurality of openings of the blade, through the plurality of openings of the teeth, for optimum containment with ultra stable vortex inside the chamber ; and controls the rate at which exhaust damper modulates based on differential pressure signal to maintain constant face velocity at the apparatus user opening and out an exhaust opening of the housing.

A single disposable cartridge for performing a process on a particle, such as particle sorting, encapsulates all fluid contact surfaces in the cartridge for use with microfluidic particle processing technology. The cartridge interfaces with an operating system for effecting particle processing. The encapsulation of the fluid contact surfaces insures, improves or promotes operator isolation and/or product isolation. The cartridge may employ any suitable technique for processing particles.

In a laboratory hood system having a housing with an access window opening into an interior work chamber for performing laboratory processes, and an air circulation system for creating an air flow from the laboratory environment inwardly through the access window into the work chamber for preventing hazardous materials from escaping into the laboratory environment through the access window, one or more air intake control devices are disposed in a selected location or locations at the access window to overcome any tendency for air turbulence to occur. The air intake control device has an air flow channel extending from an air intake opening to the laboratory environment to an air discharge opening to the work chamber, with a constriction in the channel for causing a venturi-effect increase in air velocity while flowing through the channel to promote non-turbulent air flow entering the work chamber at the selected location or locations.

A waste disposal system for the disposal of consumables through a waste chute into a waste container includes a waste chute having a first opening and a second opening, wherein the first opening is situated outside the waste container and the second opening opens toward the waste container. The first opening and the second opening are arranged at a first distance from one another, wherein the waste chute includes a plurality of self-resetting lamellae for the partial or complete closure of the openings. The lamellae form at least two lamella annuli arranged at a second distance above one another, wherein at least one first lamella annulus closes the first opening and at least one second lamella annulus closes the second opening, and the second distance between the lamella annuli is at least one third, preferably at least half and particularly preferably at least three quarters of the first distance.

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.

A multi-sample container disposal module is provided with a discharging mechanism comprising a storage box, the storage box being internally provided with a storage space, wherein the storage space is divided into a first storage cavity and a second storage cavity via a partition plate in the storage space; a transition mechanism, two ends of which are respectively a receiving end and a discharging end, wherein the receiving end is provided with a receiving rack and the discharging end is provided with a rotating structure and a discharging plate, and a driving structure is arranged between the receiving rack and the rotating structure; and a printing mechanism located above the transition mechanism, wherein the printing mechanism comprises a laser head, and a position of an emission light source of the laser source corresponds to a position of the rotating structure up and down.

Methods, systems, and apparatuses are disclosed for a tamper-resistant collection and retention a chemical sample. In one embodiment, the tamper-resistant system comprises a container operable to collect and retain a chemical sample, a tamper-resistant mechanism operable to disengage at a first chemical sample to allow for a collection of a chemical sample, wherein the tamper-resistant mechanism is operable to record one or more of: a date, a time, and a location, of the chemical sample during the collection of the chemical sample, and wherein the tamper-resistant mechanism is further operable to re-engage and lock after the collection of the chemical sample to resist subsequent chemical samples after the first chemical sampling.
