The invention relates to a tissue processor (100) for automatically processing histological tissue specimens, the tissue processor (100) comprising a plurality of containers (1, 2, 3, 4, 5, 6, 7) each being provided for a respective histological process for processing at least one tissue carrier, a robotic arm (9) for handling a tissue carrier between the containers (1, 2, 3, 4, 5, 6, 7) for being processed in each of the containers (1, 2, 3, 4, 5, 6, 7), and a control unit for controlling the histological process in each of the containers (1, 2, 3, 4, 5, 6, 7) and for controlling the robotic arm (9), wherein the control unit is configured such that the robotic arm (9) handles a tissue carrier between the containers (1, 2, 3, 4, 5, 6, 7) while the histological process in each of the containers (1, 2, 3, 4, 5, 6, 7) continues in an uninterrupted fashion, so that the execution of the process for each tissue carrier is independent from the loading order and/or process duration of other tissue carriers being processed in the containers (1, 2, 3, 4, 5, 6, 7).

An apparatus for a sterile transfer of a material incudes a second safety device which locks an actuation mechanism in a closed position and unlocks the actuation mechanism when a container flange is correctly connected to a port flange, a third safety device which locks the container flange connected to the port flange when the actuation mechanism leaves the closed position, and a fourth safety device which blocks a return of the actuation mechanism from the open position to the closed position when the port door is open. The second, third and/or fourth safety device comprises two magnetic elements with at least one closed wall being arranged between the two magnetic elements. The two magnetic elements are configured to mutually attract or to mutually repel through the at least one closed wall either in a lock position or in an unlock position of the second, third and/or fourth safety device.

An observation sample covering implement is provided with an ultra-thin film for covering an observation sample, and a main body portion including a holding portion having opening portion formed therein, characterized in that: the ultra-thin film is formed to be larger than the opening portion; and the ultra-thin film is held onto the holding portion by being stuck by physical adsorption to at least an upper surface and a portion of a side surface of the holding portion in such a way as to close the opening portion.

A microfluidic channel and a preparation method and an operation method thereof. The microfluidic channel includes: a channel structure, including a channel for a liquid sample to flow through and a channel wall surrounding the channel. The channel wall includes an electrolyte layer made of an electrolyte material; and a control electrode layer, at a side of the electrolyte layer away from the channel. The control electrode layer overlaps with the electrolyte layer with respect to the channel.

A sample preparation module accepts a sample including a target analyte. The sample preparation module processes the sample through several reaction chambers and a solid phase column. Different reagents are present in the reaction chambers. The eluted analyte is then transferred to the amplification module, where it is further processed and amplified for optical analysis.

The present application relates to a biochemical reaction test tube and a use method thereof, and a gene amplification kit. The biochemical reaction test tube includes a tube portion and a cover portion. The tube portion includes: a tube body including a first chamber and a second chamber, where a bottom of the second chamber is spaced apart from a bottom of the first chamber; and a limit unit provided at an outer side of the tube body. The first chamber and the second chamber are provided at different heights and used to hold different reaction components and solutions. Only one of the first chamber and the second chamber is heated to complete a biochemical reaction. When the test tube is vertically flipped at 180° and shaken, the solutions in the first chamber and the second chamber are mixed to further achieve a reaction, which eliminates harmful results.

An arrangement includes: a holding device including holding elements; and contain-ers, each of the containers including a container wall which at least partially surrounds a container interior. The container wall has an exterior surface which faces away from the container interior. Each of the containers is detachably held by at least one of the holding elements by contact of the at least one holding element to the exterior surface of the container wall of the respective container. Directly after the arrangement has been subjected to a transport simulation, a number of particles of a particle size of at least 5 μm on the exterior surfaces of the containers does not exceed 2.7 particles per cm.sup.2 of a sum of surface areas of the exterior surfaces of all the containers, the transport simulation consisting of a rotational flat drop test and a random vibration test which are conducted in that order.

A heating structure includes a first cover plate, a second cover plate, a conductive portion; and two first driving electrodes. The conductive portion is connected to the first cover plate and the second cover plate. The first cover plate, the conductive portion, and the second cover plate cooperatively define a channel for carrying a microbead. The channel includes a flow path. The two first driving electrodes are electrically connected to the conductive portion to energize the conductive portion. When the conductive portion is energized, a driving force is generated to drive the microbead away from a sidewall of the conductive portion to the flow path. A nucleic acid detection kit with the detection chip, and a nucleic acid detection device with the nucleic acid detection kit are also disclosed.

A safety cabinet that includes an opening portion in a front surface of a work space and a front shutter, and supplies purified air into the work space from above. The front shutter slides in an upward and downward direction to close a part or an entirety of the opening portion. The front shutter includes a small window shutter that slides in a lateral direction.

A cartridge comprising a cartridge body and a capture medium holder disposed within the body, the capture medium holder comprising a platform configured to receive a capture medium, the capture medium holder being configured to move relative to the cartridge body between a sample collection position in which the platform is aligned with a sample inlet of the cartridge body and an inspection position in which the platform is aligned with an inspection window of the cartridge body.
