A method for preparing a filtered beverage includes filtering a raw beverage using a cross-flow ultrafiltration device to produce a solids fraction and a liquid fraction; heating the solids fraction to a temperature of 60° C. or greater to produce a pasteurized solids fraction; microfiltering the liquid fraction through a microfilter having a size cut-off of 1 μm or smaller to produce a microfiltered liquid fraction; and combining the pasteurized solids fraction and the microfiltered liquid fraction to result in the filtered beverage.

The present application provides methods and systems for viral clearance for purifying an antibody from a sample comprising one or more impurities including viral particles. The method is conducted in a system which includes a hydrophobic interaction chromatography (HIC) column and a virus retentive filtration (VRF) system. The HIC column and the VRF system are connected inline in a continuous processing system, and the VRF system comprises at least two filter trains in parallel.

The present disclosure sucks air in hospital room using a compressor to maintain an inner portion of the hospital room in a negative pressure state, and creates a high-temperature and humid environment by a water spray, the compressor, and a sterilization chamber to kill bacteria or viruses. In addition, the compressor uses power generated by a turbine, and is configured so that heat of air coming out of the compressor is recovered to a suction side of the compressor, such that efficiency of a system may be secured. Further, some of clean air generated while passing through the sterilization chamber may be directly supplied again to the hospital room through a bypass means.

A filter unit for a mixing apparatus includes a hydrophilic filter and a hydrophobic vent filter. The hydrophilic filter is configured to receive a fluid including a liquid and gas. The hydrophilic filter is further configured to sterilize the liquid. The hydrophobic vent filter is configured to receive the gas from the hydrophilic filter. The hydrophobic vent filter further includes a vent and a membrane configured to separate an interior of the filter unit from an exterior of the filter unit, the gas being vented from the filter unit by flowing across the membrane and out of the vent. In some embodiments, the filter unit further includes a defoaming device configured to receive gas, foam comprised the liquid containing trapped gas, and some of the liquid from the hydrophilic filter and is further configured to release at least some of the gas from the foam.

A sterilization process challenge device configured to test the efficacy of a sterilization process includes a tubular body for containing at least one sterilization indicator and a filter assembly including at least one filter member. The only flow path into the interior of the tubular body containing at least one sterilization indicator is provided through the filter assembly to control and restrict flow of a gaseous sterilization medium from an external environment.

The invention relates to a personal, reusable straw and a case comprising a holder for the straw, where the case comprises elements to flush, wash, clean, sanitize, and/or dry the straw in the holder. A pump may pump fluid from a fluid reservoir to lead fluid into and/or around the straw. A fan may blow air to the straw for drying the outside and/or inside of the straw. A heating element may dry the straw. A UV or other light source may provide light which is directed to sanitize the outer and inner surfaces of the straw. A controller in the case may control these elements. The controller may include a wireless transceiver for communication with a mobile application to enable a user to control the elements manually and/or via a program.

The multifunctional respiratory mask according to the invention for separating fine dust, pollen and/or viruses from breathing air has a shielding device that forms an outer and/or inner air chamber in the face region of a wearer and shields it from the environment against fine dust, pollen and/or viruses. In addition, a forehead bracket is provided having a housing arranged in the region of the forehead of the wearer and having two holding brackets, each formed laterally thereon, in the manner of eyeglass temples. A connecting line connects the housing with the air chamber closest to the face of the wearer, wherein at least one blower integrated into an air duct, a power supply, and a textile filter element are arranged in the housing. In addition, a metal plate filter element is arranged in the air duct, which forms a filter unit with the textile filter element, wherein the metal plate filter element and the textile filter element are arranged to be individually exchangeable in the housing and the power supply applies a voltage to the metal plate filter element by means of a switch or disconnects it therefrom and/or, when switched on, heats it to a temperature of at least 60° C.

A multiple-bore solute cartridge carrier 10) for use in a sterile fluid delivery system. The carrier includes a rotary housing (12) adapted for connection to the sterile fluid delivery system. The rotary housing has one or more bores (30) configured to receive a solute cartridge. The rotary housing, when connected to the sterile fluid delivery system, is selectively rotatable to facilitate creation of a desired sterile solution when sterile water from the fluid delivery system is flowed through the solute cartridge.

The invention relates to a membrane which can be used for cultivating adherent or suspension cells, in particular adherent cells, wherein said membrane allows for the adhesion and proliferation of the cells due to the irradiation of the wet or dry membrane with gamma- or beta-rays or an electron beam in a dose of from 12.5 to 175 kGy in the presence of oxygen. The resulting membrane may be used without any pre-treatment with surface-modifying substances. The invention further relates to a method for preparing said irradiated membrane which can be used for the cultivation of cells, in particular adherent cells, and to methods of using such a membrane for the cultivation of cells, in particular adherent cells.

One aspect of the present disclosure can include a system for dispensing purified and sterilized fluid and/or solution. The delivery system can include a fluid reservoir, a sterilization and/or purification mechanism, a solution production mechanism, a dispensing mechanism, and a controller. The system can dispense the purified and sterilized fluid and/or solution on-demand.
