The present invention discloses a sealed fluid transfer device and a sealed fluid transfer method. The device includes a first container puncture apparatus, a second container puncture apparatus and a fluid transfer apparatus, wherein the fluid transfer apparatus includes a first container puncture adapter, a second container puncture adapter and a pressure supply unit; the first container puncture adapter includes a sealing element fixed seat, a guided outer casing, a pipeline fixed seat, a first fluid pipeline and a second fluid pipeline; when the sealing element fixed seat is connected with the first container puncture apparatus, a first sealing element is firstly tightly connected with a second sealing element, the first fluid pipeline and the second fluid pipeline respectively pass through the two sealing elements and then communicate with the first container; after being firstly used, the first fluid pipeline and the second fluid pipeline are always in no contact with the exterior; the fluid in the second container and the fluid in the first container are transported in an internal manner so as not to be in contact with the outside air, thereby avoiding the direct contact of the hazardous fluids with the air or the human body.

Concentrated liquid flavorings and methods of preparing flavored beverages using the concentrated liquid flavorings are described herein. The concentrated liquid flavorings are shelf stable for prolonged storage times at ambient temperatures. Shelf stability is provided, at least in part, by acidic pH and/or reduced water activity. By one approach, the concentrated liquid flavorings are intended to provide flavor to a beverage, such as coffee, tea, milk, or other savory beverage. The concentrated liquid flavorings may be provided in a convenient portable and dosable format that can be easily used by a consumer to provide the desired flavor and amount of flavor to a beverage.

The present invention presents an automatic compounding machine for food and medicine and relates to the technical field of food and medicine preparation. An automatic compounding machine for food and medicine, including a hatch, the hatch is provided with an automatic powder dropping module for feeding special powder, an automatic water filling module for feeding water, and a bottle holder for supporting a mixing bottle; the bottle holder is provided with a first drive motor, and the drive shaft of the first drive motor is provided with a first mounting plate, and the first mounting plate is provided with two magnetic blocks at intervals. The present invention can be used for mixing and stirring the contents of solid food, tablets or capsules with special powders and pure water into a liquid suspension, thus facilitating the taking of solid food or drugs, and the accurate dosing division of drugs, saving time and effort with high preparation efficiency.

Provided are an ultra fine bubble production apparatus and production method capable of collecting ultra fine bubbles efficiently. To this end, a cooler unit is controlled so that a temperature of a liquid in a collector unit can be lower than a temperature of a liquid containing ultra fine bubbles generated in an ultra fine bubble generation unit.

A multi-level port vessel includes a vessel body defining an interior volume. The vessel body has a front wall, a rear wall, two side walls, a bottom, and a top. The top is open and adapted to be covered by a removable lid. A vertically oriented mixing wheel is disposed within the interior volume. The vertically oriented mixing wheel has a substantially horizontal rotation axis when the vessel body is disposed on a substantially horizontal surface. A plurality of ports is disposed in one of the rear wall, the front wall, or the side walls. At least one port in the plurality of ports is located at an elevation that is at least partially encompassed by a projection of the perimeter of the vertically oriented mixing wheel.

Disclosed herein are apparatuses and methods for conducting multiple simultaneous micro-volume chemical and biochemical reactions in an array format. In one embodiment, the format comprises an array of microholes in a substrate. Besides serving as an ordered array of sample chambers allowing the performance of multiple parallel reactions, the arrays can be used for reagent storage and transfer, library display, reagent synthesis, assembly of multiple identical reactions, dilution and desalting. Use of the arrays facilitates optical analysis of reactions, and allows optical analysis to be conducted in real time. Included within the invention are kits comprising a microhole apparatus and a reaction component of the method(s) to be carried out in the apparatus.

The present invention relates to a method for producing and delivering a gas mixture having a selected composition of a first gas and at least one second gas, comprising the following steps: (a) providing a main gas flow comprising the first gas in a main conduit, (b) separating the main gas flow into a first plurality of secondary gas flows, (c) guiding each secondary gas flow through a secondary conduit, (d) adding at least one second gas to at least one of the first plurality of secondary gas flows in the respective secondary conduit through a delivering conduit, said delivering conduit protruding into the secondary conduit, and (e) combining the first plurality of secondary gas flows to the gas mixture. With the technical teaching of the present invention a dynamic gas bottle filling is possible wherein the second gas components may have a concentration form some ppb to percent.

One or more embodiments relate to systems and methods for mixing of two or more fluids using a multi-chamber manifold. One or more embodiments relate to optimal mixing.

Cartridges for the isolation of a biological sample and downstream biological assays on the sample are provided, as are methods for using such cartridges. In one embodiment, a nucleic acid sample is isolated from a biological sample and the nucleic acid sample is amplified, for example by the polymerase chain reaction. The cartridges provided herein can also be used for the isolation of non-nucleic acid samples, for example proteins, and to perform downstream reactions on the proteins, for example, binding assays. Instruments for carrying out the downstream biological assays and for detecting the results of the assays are also provided.
