A device (1) and method for media filtration with a preparation container (2). A chamber (5) containing a dissolvable medium (29) is situated between the container inflow and outflow, and has a filter (22). A mixing arm (6, 7), connected to the inflow, protrudes into the medium in the chamber with at least one mixing nozzle (19, 20), disposed at the free end (17, 18) of the mixing arm for generating a directed jet of solvent. The preparation container has bottom (10) and top (8) parts bracketing the chamber. The filter is a sterile, has on the filtrate side facing the outflow, a circumferential outer edge (23) resting on a circumferential rest edge (37) of the bottom part of the preparation container and is connected fixedly thereto. A sterilised filtrate space (39) is formed between the filtrate side (38) of the filter and the outflow situated in the bottom part.

Devices and methods manually open glass ampules within the devices. One device may include a holder having at least one deformable side wall, a supporting element, and at least one strainer/filter arranged below the holder so that the content of the opened glass ampule may flows therethrough. A first lever of the device may pivot around a first axis and a free end of the first lever may be pressed against the deformable side wall of the holder. A second lever of the device may pivot around a second axis that may divide the second lever into a short lever arm and a long lever arm. The short lever arm may be pressed against the first lever and a glass ampule may be broken open by pressure of the free end of the first lever.

This invention relates to a particle extractor assembly 10, 100 which is used to extract and collect dust and/or other airborne pollutants from a workface. The assembly 100 is mobile as is mounted to a base 12 which includes a first platform 12.1 and a second pivotal platform 12.2 which is articulated to the first platform 12.1 and is configured to be pivotally displaced relative to the first platform between a lowered position and a discharge position in which it is inclined with respect to the first platform 12.1. The assembly also includes a vacuum pump 150 powered by an electrical motor 160, a particle filter 200 to filter out particles upstream of the vacuum pump and a drum arrangement which includes a collector drum 170 configured to rotate about an axis to mix its contents to form a slurry and it discharge the contents when in the discharge position.

A fecal grinder assembly includes a container defining an open interior volume and a plurality of container teeth extending from a bottom wall of the container and within the open interior volume, a grinder slidably positioned within the open interior volume of the container, the grinder including a base and a key extending from the base in a first direction and a plurality of grinder teeth extending from the base in a second direction opposite the first direction, and a collection member including a filter portion and a collection body extending from the filter portion, a keyway extends through the filter and the body for receiving the key of the grinder when the collection member is positioned on the grinder and within the open interior volume of the container.

Disclosed are devices and methods for synthesizing products. The disclosed devices and methods may be used to synthesize products, e.g., pharmaceutical or therapeutic compounds (i.e., drugs), ceramics, catalysts, biological polymers (i.e., proteins, enzymes), cells, tissues, or combinations thereof. The devices and methods may be operated in a microgravity environment.

A combination crystallizer washer filter dryer device and methods of using the device for producing washed and dried product of a reaction are disclosed. The device consolidates the functions of a crystallizer with the filtering, washing, and drying steps to a single vessel, eliminating the need for an additional crystallizer separate from the filter washer dryer device, the transfer of a reaction product or crystallized product from a crystallizer to a subsequent vessel for completing the filtering, washing, and drying process of the solid phase of the slurry.

A powder rotary fluidization device and a method thereof are provided. The powder rotary fluidization device includes a support device, the support device is provided with an installing plate, the installing plate is provided with a power device and a fluidization device, and the power device is in transmission connection with the fluidization device. After a position of the fluidization device on the installing plate is adjusted through the support device, the power device is started to drive the fluidization device to rotate, and meanwhile gases are introduced into the fluidization device to process powder. and therefore the problem of poor processing effect on fine powder with high viscosity is solved through the rotatable fluidization device.

A volatiles consuming eductor system for coated scrap metal furnaces with separate delacquering and melt chambers. Motive gas is forced through an inlet into a mixing chamber in a direction opposite a suction port, creating a Venturi that draws gases from the delaquering chamber through the mixing chamber. The motive gas and the drawn gases mix and are forced through a discharge port, ignited, and injected into the melt chamber to help heat the melt chamber. A computer monitors process conditions and controls a regulator that adjusts the motive gas flow in response to those conditions.

A dissolution system includes a dissolution line and a bypass line. The dissolution line fluidly couples a biocontainer, a pump, a cartridge, an upstream filter, and a downstream filter in a circulation loop. The bypass line is in fluid communication with the dissolution line at an upstream junction and a downstream junction such that the bypass line is in parallel relationship with the cartridge. A flow control system is configured to control the flow of fluid through the cartridge such that the flow of fluid through at least one of the dissolution line and the bypass line is selectively controlled based upon a pressure in the dissolution line downstream of the cartridge between the cartridge and the biocontainer.

The present invention provides a liquid dispensing apparatus, for use with a first container where a first liquid is contained, comprising: (a) a second container where a second liquid is contained, said second container is provided with a container outlet for dispensing said second liquid; and (b) a utility potion, comprising: an outlet, for dispensing liquid; a first inlet, collaboratively operating with a pressure valve for intaking said first liquid enabling a first passageway; and a second inlet, operatively working with said container outlet, enabling a second passageway for controllably intaking said second liquid from said second container to said second inlet.
