Abstract:
A reagent vessel (100) for an analytical instrument is disclosed. The reagent vessel (100) is configured to store a liquid reagent. The reagent vessel (100) comprises a cover (102) and a lower part (104).The lower part (104) comprises a bottom wall (106), a front wall (108), a rear wall (110), two opposing side walls (112)and at least one connection wall (116). The cover (102), the bottom wall (106), the front wall (108), the rear wall (110) and the two opposing side walls (112) define at least one internal volume (114) for storing at least one liquid reagent. The two opposing side walls (112) are at least partially connected to one another by means of the at least one connection wall (116) located within the at least one internal volume (114).The connection wall (116) is spaced apart from the bottom wall (106).The connection wall (116) and at least the two opposing side walls (112) are injection-molded and monolithically formed. Further, an apparatus (148) and a method for manufacturing a lower part (104) of a reagent vessel (100) are disclosed.
Abstract:
Provided herein are apparatuses, systems, kits and methods for sterilely delivering fluid to an elongated swab. In particular, provided herein are apparatuses configured to sterilely deliver a desired fluid to a swab contained within a swab housing. Apparatuses for delivering fluid to an elongated swab contained within an elongated swab housing are provided. The apparatus comprises a hollow main body having therein a chamber containing a fluid, a hollow applicator body positioned beneath the hollow main body, the hollow applicator body having therein a puncturing element, and an open channel positioned beneath the hollow applicator body, wherein the open channel is configured to connect with an elongated swab housing containing an elongated swab. Puncturing of the chamber results in flow of the fluid through the interior of the hollow main body, through the hollow applicator body, and through the open channel and out the open channel.

The reagent manager housing is for housing reagent bottles. The high-speed reagent bottle spinning device is disposed within the reagent manager housing for spinning at least one of the reagent bottles. The processor is in electronic communication with the high-speed reagent bottle spinning device. The memory is in electronic communication with the processor. The memory includes programming code for execution by the processor. The programming code is configured to spin the high-speed reagent bottle spinning device to spin the at least one reagent bottle to remove microparticles from a bottom surface of a septum of the at least one reagent bottle.
Abstract:
Provided herein, are droplet mixture compositions and systems and methods for forming mixtures of droplets. The system may comprise two or more droplet generation units. Each unit may include at least one first input well, a second input well, and an output well connected to the first and second input wells by channels that form a droplet generator. The combined droplet populations can be mixed, heated, and collected for multiple uses, such as for use as calibration standards for instrument testing and analysis.
