The utility model discloses a kind of visual fraction recovery auxiliary with temperature control, including workbench, the top of workbench is equipped with 96-hole collection plate, for fraction collection. Among them, the bottom of workbench is provided with temperature control area, this part can carry out temperature protection to sample collection container, prevent sample from because temperature anomaly and the case of property change. Among them, it further includes connecting line, connecting line and temperature control area electrically connected. Among them, the bottom of workbench is equipped with locking device, ensure that sample collection container is firmly fixed on workbench. Among them, 96-hole collection plate is provided with color indicating lamp in each hole, and color indicating lamp and connecting line are electrically connected. In the above scheme, the utility model fraction position indication function can effectively reduce the case of "wrong use, wrong take, wrong mix" when post-processing after sample fraction collection, thereby improve work efficiency, reduce the waste of manpower, time, resource etc. of repeated work.

The utility model relates to the technical field of bottle caps, in particular to an antibacterial plastic bottle cap which comprises a bottle cap body, limiting blocks are symmetrically and fixedly connected to the two sides of the upper end of the bottle cap body, a plurality of anti-skid grooves are formed in the outer surface of the bottle cap body in an array mode, and a sealing ring is fixedly connected to the interior of the lower end of the bottle cap body. A sealing plug is fixedly connected to the top in the bottle cap body, and a plurality of limiting rings are fixedly connected to the outer side of the sealing plug in an array mode. According to the bottle cap, the sealing performance of a bottle opening can be guaranteed when the bottle cap is plugged in through the arranged sealing ring, and meanwhile the bottle cap is directly plugged in the bottle opening through the arranged sealing plug and the arranged limiting rings to improve the overall sealing performance; meanwhile, a good acting point can be found through limiting of the limiting block when the wine bottle is opened, and the wine bottle is opened easily, so that the storage problem of red wine is effectively solved.

The invention discloses a chestnut freshness locking method based on moisture migration and application thereof, and belongs to the technical field of chestnut processing. The freshness locking method for the Chinese chestnuts comprises the step of sequentially performing quick-freezing stepped treatment on the Chinese chestnuts at 4 DEG C, 18 DEG C below zero, 45 DEG C below zero and 80 DEG C below zero in different time periods. The quick-freezing stepped treatment time at 4 DEG C,-18 DEG C,-45 DEG C and-80 DEG C is 15 minutes, 15 minutes, 15 minutes and 30 minutes respectively. Before the quick-freezing treatment, the Chinese chestnuts are subjected to curing treatment. The curing treatment comprises steaming treatment and boiling treatment. According to the freshness locking method for the Chinese chestnuts, the distribution state of free water in the Chinese chestnuts is reserved to the maximum extent on the basis of water distribution and migration in different treatment processes, and the good soft and glutinous taste of the Chinese chestnuts can be kept whether the Chinese chestnuts are directly eaten after being unfrozen or eaten after being baked again. According to the Chinese chestnut freshness locking method based on moisture migration, theoretical basis and technical support are provided for freezing and freshness preservation of Chinese chestnuts.

The utility model belongs to the technical field of sewage toxicity exposure and detection, and particularly relates to an adjustable wastewater in-situ biological toxicity exposure and detection zoning device which comprises a detection shell, a partition plate which is detachable from the detection shell is arranged in the detection shell, and the interior of the detection shell is divided into a detection area and a biological chronic toxicity exposure area through the partition plate. An equipment storage box is arranged above one side of the detection shell, an aerator and a heating rod device are symmetrically placed in the storage box, and the aerator and the heating rod device penetrate through wire holes formed in the storage box through wires respectively to be connected with an external power source; the aeration machine conveys oxygen to the bottoms of the concentration detection areas and the biological chronic toxicity exposure areas through hoses, and a heating rod device of the aeration machine transmits a heat source to the corresponding detection areas or the biological chronic toxicity exposure areas through small holes in the bottom of the storage box; according to the utility model, simultaneous exposure of acute toxicity and chronic toxicity of wastewater organisms can be realized, and acute toxicity data and chronic toxicity biological samples can be obtained.
