A reaction vessel capable of measuring a light amount from a reaction liquid without degrading a function of maintaining the reaction vessel at a predetermined temperature is provided. A reaction vessel including a cylindrical shape centered on a first axis, in which an overall length in a first axis direction is longer than an overall length in a second axis direction and an overall length in a third axis direction, the second axis being perpendicular to the first axis and the third axis being perpendicular to the first axis and the second axis. The reaction vessel includes: an opening part which dispenses a liquid at a portion on one end side in the first axis direction; a first flat surface and a second flat surface which is substantially parallel to the first flat surface.

The present invention is a system and method for improving extraction of analytes from a solution by disposing a plurality of polydimethylsiloxane(PDMS) particles in a thin layer on an inner wall of an extraction vial, by increasing a surface area and volume of particles disposed to extract analytes from the solution and thereby increasing extraction capacity and speed for gas chromatography-mass spectrometry (GC-MS) analysis.

A system and associated method for concentrating and separating components of different densities from fluid containing cells using a centrifuge includes a container defining a cavity for receiving the fluid. The container has a top, a sidewall extending from the top, and a bottom disposed opposite the top and in sealing engagement with the sidewall. An insert is slidably disposed in the cavity of the container and defines a lumen through the insert. The lumen, which includes a hole and a funnel-shaped upper portion in fluid communication with the hole, forms an open fluid path between opposite ends of the insert. The insert has a density such that upon centrifugation a selected component of the fluid resides within the lumen. A container port is disposed in the top of the container to transfer the fluid into the container and to withdraw a fluid component other than the selected component from the container. The system includes a manifold that includes a manifold port, a vent to vent the container, and a connector to couple to the container port. A cannula is receivable in the manifold port and extendable through the container port into the container and into the lumen of the insert to withdraw the selected component from the lumen.

A method and a system for rapidly predicting the frying and bubbling tendency of edible oil, the method comprising: heating the edible oil, and immersing a polar component content detection probe into the oil to measure the initial polar component content of the edible oil; a frying state: removing the detection probe, placing frying food into the edible oil and frying same, extracting the frying food after frying, and observing the highest value of the frying oil bubble height and recording same as an initial bubble height; an air introduction state: immersing the detection probe into the edible oil and introducing air into the edible oil, and continuing to introduce air and heat until detecting that the polar component content of the oil has reached 10%; repeating the frying state; and formula fitting. The present method does not require actual frying, as the frying and bubbling tendency of the oil can be predicted with a 60 g sample, saving raw materials and implementing a comprehensive evaluation of the bubbling properties; the system equipment is simple, and is suitable for industrial practical operations.
