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 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.
