The disclosure includes a system comprising a first chamber having pressurized gas, a compressor connected to the first chamber (which may be a bladder), and a second chamber connected to the first chamber. The second chamber includes contents. The system also includes an exit from the second chamber. The pressurized gas from the first chamber travels into the second chamber to force the contents out of the exit of the second chamber. The compressor increases the pressure of the gas in the first chamber.

A system, method and process for disinfection of internal surfaces in aseptic tanks and pipelines by flooding with sanitizing fog in facilities designed to store liquids in general, the system having an external equipment with means to generate sanitizing fog, controlling means of gases flow rate, in-line detectors and draining means of gases inside the tank, input means of fog carrying means comprising inert gases. A disinfection process includes introduction of a sanitizing fog with droplets having a maximum size of 10 m, and 5 m in some embodiments, simultaneously with removal of gases enclosed inside the tanks and pipelines, maintaining a positive pressure inside the tanks and pipelines. The method providing reduction of oxygen concentration inside the tanks in two steps, the first step having reduction to near 10% and the second a reduction to a value below 1%, filling the tank with a sanitizing fog during the second step.

A device for unstopping a stopped specimen vessel that contains a liquid specimen such as blood is equipped with a mechanism which sucks and captures particles floating around the opening of the specimen vessel and prevents contamination of the specimen. The unstopping device grips a vessel and the stopper of the opening of the vessel, and removes the stopper from the opening of the vessel by changing the relative distance between the vessel-gripping mechanism and the unstopping mechanism. The unstopping device is equipped with: suction holes for sucking therethrough the gas which is present around the opening and contains liquid or solid particles; a pipeline which is connected to the suction holes and through which the sucked gas and particles are led downstream; a suction device connected to the pipeline; and a spirally flexed pipeline part disposed between the pipeline and the suction device.

A mounting head cleaning device is provided with a cleaning fluid supply device which supplies a cleaning fluid which is formed of positive pressure air or an oil mist to an air passage, and a control device which controls operations of a lifting and lowering mechanism and operations of a rotation mechanism, such that a nozzle shaft is lifted and lowered, and the nozzle shaft is rotated around an axial line in synchronization with a lifting and lowering operation of the nozzle shaft in a cleaning process which uses the cleaning fluid supply device.

A system comprising a first body arranged to hold liquid products and a second body arranged to hold liquid products, wherein a first end of the second body is adjacent to the first body. Sterile air is provided into the first end of the product in order to avoid heating of a product present in the first body.

The HVAC cleaning system comprises an HVAC system and a cleaning structure. The cleaning structure forms a fluidic connection with the HVAC system. The HVAC system controls a flow of air into and out of a chamber. The HVAC system controls the temperature of the air in the chamber. The cleaning structure injects a disinfection solution as a spray into the air flow controlled by the HVAC system. The disinfection solution cleans the ductwork of the HVAC system.

Provided is an apparatus for treating a substrate. The apparatus includes an exhaust unit for exhausting gas in a treatment space of a liquid treatment chamber. The exhaust unit includes: an exhaust pipe connected to the liquid treatment chamber and having an exhaust passage through which gas exhausted from the treatment space flows; a cleaning solution supply unit provided in the exhaust pipe and supplying a cleaning solution to the gas flowing through the exhaust passage; and a cleaning solution outlet pipe connected to the exhaust pipe and through which the cleaning solution supplied to the exhaust passage is discharged.

Methods and apparatus are provided for washing pipette tips, including the inside and outside of the pipette tip. Pipette wash devices comprise a main body comprising a wash chamber, a liquid channel, a gas channel, and a nozzle cavity, and a nozzle for providing a washing mist is positioned in the nozzle cavity and fluidically connected with the liquid channel and the gas channel. Methods of washing a pipette tip include inserting a pipette tip in a wash chamber; spraying a mist on an outside surface of the pipette tip; and blowing pressurized air or inert gas on the outside surface of the pipette tip, thereby washing and drying the pipette. Methods of washing a pipette tip also include passing one or more series of liquid slugs separated by gaseous gaps through the inside of the pipette tip.

A cleaning system (100) for preventing the build-up of fats, oils and/or greases in extraction and ventilation ducts. The cleaning system comprises: a pressurised gas source (102), a fluid supply tank (104) for containing a cleaning fluid, the fluid supply tank comprising a tank gas inlet (110) fluidly connected to the pressurised gas source and a tank fluid outlet (112), a nozzle (106), wherein the nozzle comprises a nozzle gas inlet (114), a nozzle fluid inlet (116) and a nozzle outlet (118), and wherein the pressurised gas source (102) is fluidly connected to the nozzle gas inlet (114) and the fluid supply tank outlet (112) is fluidly connected to the nozzle fluid inlet (116), and a controller (108), the controller configured to control flow of gas from the pressurised gas source to the fluid supply tank gas inlet, and to the nozzle gas inlet. A method of installation of the cleaning system (100) for extraction and ventilation ducts comprising: providing the cleaning system (100), and locating the nozzle (106) in a duct of the extraction and ventilation ducts. A method of preventing the build-up of fats, oils or grease on an internal surface of a ventilation or extraction duct, the method comprising: providing the cleaning system (100) and operating the cleaning system, via the controller (108) to expel the cleaning fluid from the nozzle outlet (118) into the ventilation or extraction duct.
