An automatic chemical solution formulating device combines and mixes stored solids and liquids into user specified formulations and dispenses those formulations into containers. Chemical solids are stored in cartridges of material separated into predetermined dosages (for example in reeled blister packs), avoiding the need for weighing during formulation. Elements include user interface, computer-controlled automated loading and unloading port for reagent-containing cartridges, cartridge conveyor system, reader for identifying cartridges, blister-pack strip drive system, punching mechanism to release reagents, portioning chamber to mix solvent with solids or liquids with optional portioning, accommodating formulation delivery port, position sensors, liquid flow measuring devices, liquid and gas pumps and valves, and label printer. The combination of these elements allows high-speed formulation and dispensing of user-specified formulations.

A micropump for exchanging liquid between a supply region and a working region is provided. An enclosed gas region is located above the working region. The micropump includes a capillary pipette having a closed pipette tip on a first end, an open pipette inlet disposed opposite the first end, and a pipette section enclosing the working region and disposed in a direction of the open pipette inlet from the closed pipette tip. The micropump further includes a liquid-permeable filter covering the open pipette inlet and connected to the supply region. The micropump additionally includes a capillary structure extending through the gas region between the closed pipette tip and the liquid-permeable filter.

A device for wetting biological material with at least one liquid, comprising at least one retaining device and at least suction device, wherein the retaining device serves to receive a specimen slide in a support plane, wherein the specimen slide carries the biological material, and wherein the suction device serves to suction off liquid from the retaining device, wherein a front side of the suction device does not extend parallel to the support plane. Furthermore, a retaining device for a device for wetting biological material with at least one liquid and a method for wetting biological material with at least one liquid are disclosed.

A dispenser for viscous products, including: a container for a product, a sealing cap designed to be screwed onto the container, a pipette, and a piston capable of causing a suction of the product into the pipette, the dispenser being arranged such that, when the cap is screwed onto the container, the unscrewing of the cap in the direction of opening of the dispenser causes, by itself, a movement of the piston producing the suction.

There is provided a bellows type dispensing tip, a bellows type dispensing apparatus, and a method of bellows type dispensing processing that performs highly precise dispensing processing despite having a simple structure. The apparatus comprises; two or more bellows type dispensing tips having; an accommodating section that is capable of accommodating a liquid or gas in the interior thereof surrounded by a wall face, and that has a deformable deforming wall face in a portion of the wall face, and an opening section communicated with the accommodating section, through which the liquid to be suctioned/discharged can flow in and flow out due to expansion and contraction of the interior caused by deformation of the deforming wall face; and a dispensing head that supports the bellows type dispensing tips, and that performs suction/discharge of the liquid into or from the bellows type dispensing tip, by deforming the deforming wall face.

System configured to conduct designated reactions for biological or chemical analysis. The system includes a liquid-exchange assembly comprising an assay reservoir for holding a first liquid, a receiving cavity for holding a second liquid that is immiscible with respect to the first liquid, and an exchange port fluidically connecting the assay reservoir and the receiving cavity. The system also includes a pressure activator that is operably coupled to the assay reservoir of the liquid-exchange assembly. The pressure activator is configured to repeatedly exchange the first and second liquids by (a) flowing a designated volume of the first liquid through the exchange port into the receiving cavity and (b) flowing a designated volume of the second liquid through the exchange port into the assay reservoir. The system also includes a fluidic system that is in flow communication with the liquid-exchange assembly.

A device for handling a particle suspension, in particular a cell suspension, which includes at least one channel for flowing the particle suspension, a pumping unit configured to move a driving fluid and control element for controlling the pumping unit. Also, a method for handling a particle suspension, which includes flowing the particle suspension in or out of at least one channel using a driving fluid for driving the particle suspension in the channel.

The present invention provides a rotary evaporator capable of accurately quantifying concentrated liquid and/or distillate. A distillation flask is improved into a structure having a liquid discharge opening formed at the bottom, and/or a spherical collecting flask is improved into a structure having a liquid release opening formed at the bottom. Concentrated liquid and/or distillate can be discharged without dismounting the distillation flask and/or the collecting flask. In addition, fine metering scale tubes and quantitative capacity increase units are disposed at the liquid discharge opening and/or the liquid release opening, there is a valve on the top and another valve on the bottom of each tube, so that the constant subtle changes of the amount of concentrated liquid and/or distillate can be observed, and an accurate amount of concentrated liquid and/or distillate can be discharged.

A reaction processor includes: a reaction processing vessel placing portion for placing a reaction processing vessel provided with a channel into which a sample is introduced; a temperature control system, which controls the temperature of the channel in order to heat the sample inside the channel; and a liquid feeding system, which controls the pressure inside the channel of the reaction processing vessel in order to move the sample inside the channel. The liquid feeding system maintains the pressure inside the channel to be higher than the atmospheric pressure in the surrounding of the reaction processing vessel, more preferably 1 atm or higher, during a reaction process of the sample.

An adjustable volume sampling system is disclosed for aseptically retrieving a sample volume of a fluid from an origination container. The system includes a sampling container. A cap is removably attached to the sampling container so as to close off the open top. The cap includes two ports. A first tube is attached to one of the ports. An elongated diptube extends through port into the sampling container and an upper end of the diptube is located inside a portion of the first tube. The diptube can be raised and lowered relative to the sampling container by pinching an stretching the first tube. Syringes are provided for expelling excess material from the sampling container.
