Abstract
The utility model discloses a steady temperature device, in particular discloses a steady temperature device used for a fish toxicity experiment, which comprises a cabinet body and an experimental fish tank arranged in the cabinet body. The utility model is characterized in that the lower-middle part of the inside of the cabinet body is in parallel provided with a support plate. The experimental fish tank is arranged on the surface of the support plate, and though holes are evenly arranged on the support plate. A thermostat is arranged in the cabinet body, the material of the cabinet body is transparent poly, and the peripheries of the cabinet body are fixed with a ribbed slab. The utility model makes the fish toxicity experiment carry on in the closed cabinet body, reduces temperature regulating area greatly, saves the cost, is convenient for control, and has an exact experimental environment.
Description
(1) technical field
The utility model relates to a kind of thermostat, particularly a kind of thermostat that is used for the toxicity in fish experiment.
(2) background technology
The biological monitoring of water quality is the important supplement of physics and chemistry monitoring, can reflect the comprehensive pollution situation of water body and the joint toxicity of pollutant to a certain extent, has physics and chemistry and monitors irreplaceable advantage.Obtained more application at biological monitoring Mesichthyes toxicity test, its main contents are: the tested fish class is put into the water body of the known or unknown poisonous substance of variable concentrations, and various reactions and the survival condition of fish observed in record.The toxicity in fish experiment mainly comprises fish acute toxicity experiment, subacute toxicity test and chronic toxicity test.The fish acute toxicity experiment can be measured the middle and high concentration pollutant and (be generally 72 hours at short notice, be no more than 120 hours after the prolongation) to acute toxicity effect that fish produced, determine MLC (median lethal concertration) (LC50) whereby, and be used for estimating the toxicity size and the character of pollutant.Low concentration pollutant was in a long time to the influences of fish during fish subacute toxicity test and chronic toxicity test then were mainly used to measure.In order to guarantee the stability of experimental result, be convenient to contrast, toxicity in fish requirement of experiment (about 25 degrees centigrade) is at a certain temperature carried out, and the large-scale experiment chamber generally is that the room by constant temperature reaches this condition.Investment, operating cost height except that the research institution of higher level, are generally used less between constant-temperature house.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, and a kind of small investment, the thermostat that is used for the toxicity in fish experiment that operating cost is low are provided.
The utility model is achieved by the following technical solution:
A kind of thermostat that is used for toxicity in fish experiment comprises the experiment fish jar of cabinet and Qi Nei, and its special character is: the middle and lower part in the described cabinet is provided with back up pad side by side, and the experiment fish jar is positioned at the back up pad surface, evenly has through hole on the back up pad; Thermostat is installed in the cabinet.
The thermostat that is used for the toxicity in fish experiment of the present utility model, the situation in the observation experiment fish jar for convenience: the material of described cabinet is a transparent organic glass.
The thermostat that is used for the toxicity in fish experiment of the present utility model is fixed with fastening floor around the described cabinet.Can further reinforce cabinet like this, improve the bearing capacity and the serviceable life of cabinet.
The utility model carries out the toxicity in fish experiment in the cabinet of a sealing, reduced the temperature adjustment area greatly, provide cost savings, and convenience is controlled, experimental situation is accurate.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1 cabinet, 2 experiment fish jars, 3 back up pads, 4 through holes, 5 thermostats, 6 fastening floors.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises the cabinet 1 of transparent organic glass and the experiment fish jar 2 of Qi Nei, and the middle and lower part in the cabinet 1 is provided with back up pad 3 side by side, and experiment fish jar 2 is positioned at back up pad 3 surfaces, evenly has through hole 4 on the back up pad 3; Thermostat 5 is installed in the cabinet 1; Be fixed with fastening floor 6 around the cabinet 1.
This product in use, at first water-filling in the cabinet 1 makes water level reach experiment fish jar 2 height 2/3 place, the water temperature of regulating in the cabinets 1 with thermostat 5 makes it keep a steady state value then, and then makes the water temperatures in the experiment fish jar 2 also can keep a steady state value.Back up pad 3 in the utility model is used for holding up experiment fish jar 2, is located at the certain altitude of waterline; Through hole 4 on the back up pad 3 is convenient to the circulation of water, and the coolant-temperature gage in the cabinet 1 is kept evenly and a comparatively stable steady state value.
Claims (3)
1. one kind is used for the thermostat that toxicity in fish is tested, comprise cabinet (1) and the experiment fish jar (2) in it, it is characterized in that: the middle and lower part in the described cabinet (1) is provided with back up pad (3) side by side, experiment fish jar (2) is positioned at back up pad (3) surface, evenly has through hole (4) on the back up pad (3); Thermostat (5) is installed in the cabinet (1).
2. the thermostat that is used for the toxicity in fish experiment according to claim 1, it is characterized in that: the material of described cabinet (1) is a transparent organic glass.
