A process is disclosed for reducing loss of hydrogen in solution to the fractionation section of a hydroprocessing unit. The hot liquid stream is stripped with an inert gas in a hot flash stripper to urge hydrogen into the hot flash vapor stream. Substantial conservation of hydrogen gas is achieved.

Disclosed are apparatuses, systems, and methods for performing electroporation.

According to an embodiment, a sample processing apparatus includes a detection section configured to detect pose information regarding a sample container which is configured to house a sample; and a raising section which turns the sample container in a predetermined direction based on the pose information regarding the sample container to raise the sample container.

Methods and apparatus to mitigate bubble formation in a liquid are disclosed. An example apparatus disclosed herein includes a bottom wall, a first baffle cantilevered from the bottom wall, and a second baffle cantilevered from the bottom wall. The first baffle is spaced apart from the second baffle, and the first baffle and the second baffle are positioned radially relative to an axis of rotation of the apparatus.

Blood collection apparatus includes a blood collection container and a mix detection unit operatively coupled to the blood collection container. The mix detection unit includes a device to produce a data signal indicative of the extent to which the blood collection container is moved in a manner to promote mixing of blood collected into the container and an anti-coagulant also present in the container. A method described herein provides for filling a blood collection container with blood, inverting the blood collection container by hand to mix the blood with an anti-coagulant, and viewing or listening to an indication generated by a mix detection device attached to the blood collection container, wherein the indication provides information about the appropriate amount of mixing for the blood.

The present invention relates to a biological sample preservation tube with an identification code, wherein an information element which records the sample information is fused integrally with the bottom wall and/or side walls during molding the preservation tube, the preservation tube is suitable for the preservation of a biological sample at low temperature and can ensure the effectiveness and stability at low temperature; and at the same time also relates to a method for manufacturing the biological sample preservation tube, wherein the preservation tube is molded by a one-step process, without an additional secondary processes for manufacturing the identification code, the method improves the production efficiency, reduces the production cost, employs multi-point symmetrical feeding, and has good quality and stability of the product, so that the method is of great significance as it opens up a new idea for developing and producing the similar product in the industry, especially the small-sized preservation tube with an identification code.

A tube for chemical, biological or biotechnological matter is provided, wherein the tube has a positioning element, the positioning element shaped for engagement in a corresponding structure provided in a carrier.

A sample ampoule for calorimetric measurements includes a vial, a lid and a sealing member. The vial, lid and sealing member are adapted to form a hermetically sealed sample ampoule. The vial has a first contact surface and the lid has a second contact surface, the first and second contact surfaces are in contact with each other in a sealed position of the ampoule, and the vial and lid are formed out of materials with different strength.

A stool container is provided with a lid body (2) having a lid part (2a) for sealing a container and a stool collection rod (2b) for collecting stool, a cylindrical container body (3) that has a liquid reservoir (3b) formed at the distal end thereof via a filter holding part (3a) and has an open proximal end, and an inner plug 4 that is inserted from the proximal end of the container body (3) in to the container body (3). The distal end of the inner plug (4) has a bottom surface (4a) that is orthogonal to the longitudinal direction and, in the center of the bottom surface (4a), a scraping part (4b) through which the stool collection rod (2b) can be inserted. A stool collection rod guide part is formed that comprises a plurality of sloping ribs (4c) disposed radially around the scraping part (4b).

An in-vial microextraction (IVME) device is a vial with at least a portion of the inner surface having a sol-gel coating that absorbs at least one target analyte. The sol-gel coating is a metal oxide comprising coating that is formed from a tri- and/or tetra-functional metal comprising precursor that condenses to form a gel network. The IVME device can be used to prepare a sample by the contacting of the IVME device with a solution or suspension. An analytical method is enabled where the absorbed analyte from the IVME device is subsequently desorbed with a solvent or solution or thermally desorbed and analyzed using GC-MS or LC-MS or other analytical instrument for separation and detection.
