A bypass flow monitoring chamber that may be retrofit onto the main chamber of an incubation chamber, for continuous collection of environmental samples. This allows for the measurement and correction of the environmental conditions within the chamber, and the return of the sample to the main chamber. Utilizing this sampling method, the separable bypass flow monitoring chamber may be isolated from the main chamber by a set of valves during a period of high-heat decontamination of the incubator therein protecting the sensors and contents of this separable chamber, as well as allowing the use of less expensive and lower temperature rated incubator sensors.

A microfluidic device for amplifying a nucleic acid includes a cartridge and a control part. The cartridge includes a tank part and a plurality of first chambers. The control part is configured to control execution of a thermal cycle, count a number of repetitions of the thermal cycle for each of the first chambers and store a count value, acquire a fluorescence intensity of each of the first chambers for each thermal cycle, and reset the count value of a defective chamber of which the fluorescence intensity is not within a predetermined range, discharge the solution from the defective chamber, and fill the defective chamber with a new solution from the tank part.

Geranyl pyrophosphate (GPP) is a key intermediate molecule in the bioproduction of thousands of natural products. Currently, natural products are either cultivated from plants, synthesized via complex chemical synthesis strategies, or through cell-based factories also known as biofoundries. However, in order to replicate the process in a cell free environment, numerous enzymes and cofactors must be utilized making this approach costly and unviable. In order to make this process viable, a new approach was needed that uses fewer enzymes and cofactors. As described herein, the present invention demonstrates that it is possible to create GPP from glycerol through a short and concise biosynthetic pathway outside of the cell.

An incubator for cell and tissue culture under controlled atmospheric conditions has a primary air flow control device that forms a primary, preferably laminar flow, air veil across an opening that allows access to the cells or tissue cultures disposed within the incubator. Preferably, most if not all of the air in the primary (laminar flow) air veil is recirculated, and a secondary air flow control device is used that forms a secondary, preferably laminar flow, air veil between the primary (laminar flow) air veil and a user of the incubator.

An aid device, for manually emptying contents of a tube, including: a housing, a clamp, coupled to the housing and configured to secure a position of the tube in relation to the housing, wherein the tube includes a plunger configured to slide within the tube between an inlet end of the tube and an outlet end of the tube, a pusher configured to abut the plunger, and a lever pivotally coupled to the pusher by a first rotational axis such that the lever is continuously rotatable between an open configuration and a closed configuration about the first rotational axis, thereby facilitating a continuous movement of the pusher from the open configuration to the closed configuration, wherein the clamp is configured to secure the position of the tube such that the plunger of the tube is positioned between the outlet end of the tube and the pusher.

An automatic analysis device includes a probe that performs a dispensing operation including a suction process and a discharge process with respect to liquid; a syringe that generates a pressure change for dispensing liquid at the probe; a flow path that connects the probe and the syringe with each other; a pressure sensor that measures the pressure change in the flow path at the time of liquid dispensing; a storage portion that stores a pressure change of time-series when reference fluid is discharged as a reference discharge pressure waveform; and a determination portion that determines whether or not there is an abnormality in the suction process of the sample from a relationship between a value of difference or a ratio between the reference discharge pressure waveform and the pressure waveform of a determination target at the time of discharge of liquid and normal range.

Reusable network of spatially-multiplexed microfluidic channels each including an inlet, an outlet, and a cuvette in-between. Individual channels may operationally share a main or common output channel defining the network output and optionally leading to a disposable storage volume. Alternatively, multiple channels are structured to individually lead to the storage volume. An individual cuvette is dimensioned to substantially prevent the formation of air-bubbles during the fluid sample flow through the cuvette and, therefore, to be fully filled and fully emptied. The overall channel network is configured to spatially lock the fluidic sample by pressing such sample with a second fluid against a closed to substantially immobilize it to prevent drifting due to the change in ambient conditions during the measurement. Thereafter, the fluidic sample is flushed through the now-opened valve with continually-applied pressure of the second fluid. System and method for photometric measurements of multiple fluid samples employing such network of channels.

A liquid delivery device that includes a channel having an inner section lower than 9 mm.sup.2 and inner volume lower than 50 mL, a gas mass flowmeter connected to the inlet of the channel, and a pressure control unit suitable to control pressure inside the channel by flowing gas through the gas flowmeter.

A fluid delivery device includes at least one area onto which at least one support element having at least one well may be placed in a defined position. The fluid delivery device further includes at least one pipetting device having a connector configured to releasably connect the at least one pipetting device with a disposable tip and with a fluid displacement element which enables aspiration and ejection of a defined volume of liquid to or from the disposable tip. The at least one pipetting element is movable in a vertical and preferably in at least one horizontal direction. The fluid delivery device also includes a blowing element that has at least one aperture coupled to a source of pressurized gas and is movable in a vertical and preferably at least one horizontal direction. A system includes such a fluid delivery device and the at least one support element.
