By a one-time sample suction and a detection with the same background, All the detection test paper strips (6) which are sealed and fixed in the device can carry out the parallel combined detection with various tumor markers at one time within a plurality of minutes by using the naked eye, so as to lead the detection of a plurality of indexes of tumor markers to become more simple, safe and rapid; furthermore, a cross interference can be avoided, and the waste after the detection is still sealed in the detection tube, which is more conductive to the environmentally protective treatment of the waste.

The invention relates to a pipette-tip container (1) comprising a container (3) and a cover (4), which covers the container in its closed position (3) receiving opening (12). The cover (4) has a standardized mounting surface and is designed as an adapter element for the receiving shell (3). A positioning device (25) with a plurality of positioning elements (26) is arranged on the cover (4). The housing (3) is supported by its base (7) on the cover (4), wherein the housing (3) is fixed relative to the cover (4) by means of the positioning element (26). The mounting surfaces are positioned relative to each other in a positioning position for automated sample processing. Furthermore, the invention also relates to a method for providing such a pipette tip container (1).

The present invention relates to a vacuum loader assembly wherein the assembly is comprised of a frame, a first and second tube, a flexible tube, a motor, and a sweeper assembly. The frame is adapted to be positioned over an opening of the container. The first tube is mounted to the frame and is in fluid communication with a vacuum source. The second tube is rotatably mounted to the first tube and is also in fluid communication with the first tube and the sweeper assembly is mounted to the second tube. The flexible tube extends from the second tube such that, when the frame of the present invention is placed over a container, the second tube, flexible tube, and sweeper assembly are lowered into the container and rotated by the motor such that, when the vacuum source is activated, the flexible tube suctions out the contents of the container.

A method for automatically distributing circulating cooling water to the side filter, the water outlet of the circulating water cooling structure [1] is connected with a water turbine pump [3], the water outlet of the water turbine pump [3] is connected to the inlet of the side filter, and the water turbine pump [3] The draft pipe is connected to the suction pool [5] or the cold water channel, and the circulating water cooling structure [1] supplies water to the water turbine pump [3], and the potential energy generated by the head of the circulating water drives the water turbine pump to pump the cooled circulating water Distribution side filter [6]. The side filter does not consume system energy and uses water energy. The side filter is not troubled by the pressure of the inlet water; the side filter filters the cooling water without affecting the temperature of the circulating water. The side filter has a large amount of water, which can better control the water quality and improve cooling. Effect.

The invention discloses a method for micro-measurement of breast milk. The method for micro-measurement of breast milk in the present invention uses the measurement principle of the instrument as follows: the qualitative and quantitative analysis of the substance is carried out by utilizing the absorption phenomenon of light of different wavelengths by the substance, which conforms to the Lambert-ratio Ear law, including the following steps, 1) Calibration of the instrument; 2) Sample centrifugation: Put the breast milk sample in a centrifuge tube for later use. Do not stand it upside down or shake it when taking it out, so as not to make the sample turbid. The disposable needle tube is inserted into the centrifuge tube from the wall of the centrifuge tube to suck out the clarified breast milk supernatant in the middle of the centrifuge tube and inject it into the test tube for later use; 3) Sample detection; method, the amount of breast milk used is small, the waste of breast milk is reduced, and the detection method is simple and convenient.

This invention relates to a container emptying apparatus including a frame, a first and second tube, a suction tube, a motor, and a sweeper. The frame is adapted to be positioned over an opening of the container. The first tube is mounted on the frame and is in fluid communication with a vacuum source. The second tube is rotatably connected to the first tube and is also in fluid communication with the first tube. The sweeper assembly is connected to the second tube. The suction tube extends from the second tube such that, when the frame of this invention is placed over a container, the second tube, the suction flexible tube, and the associated sweeper assembly are lowered into the container and rotated by the motor such that, when the vacuum source is activated, the suction tube suctions the contents from the container.

The invention discloses an anti-blocking suction tube, which comprises a suction tube body, the side wall of the suction tube body is provided with opposite installation holes, and a cut-off for preventing the passage of obstructions is provided in the installation holes for sliding fit. The dirt plug, the dirt intercepting plug includes at least two plug bodies, the plug bodies are provided with dirt intercepting holes and the plug bodies can be inserted into the suction pipe through the installation holes alternately, the anti-blocking suction pipe of the present invention can effectively avoid The suction tube is blocked by bone debris and muscle tissue, reducing operation time and risk.

The invention discloses a ceramic fiber pipe pumping filtration molding system and method. The system includes: a rotatable first roller and second roller; a rotation driving mechanism that drives therollers and is in fixed connection with a first gear, which is in engaged transmission with gear rings outside the rollers, wherein the rollers are both coaxially equipped with dies having holes on the walls internally, and the die consists of two half pipes that can be buckled together and has one opening end and one closed end; and an automatically detachable first end cover and second end cover arranged at the left and right ends of the rollers, as well as a guide plate spirally sleeved between the rollers and the tubular dies. The two rollers in the system share the two detachable end covers, so that ceramic pipe processing in the two rollers can be carried out alternately, thus improving the overall efficiency. In addition, the disposed guide plate makes the thickness of the manufactured ceramic pipe more uniform.
