III. Technical Specifications:
The size of the toxicology fish rack is no more than 160cm in length, 70cm in width, and 230cm in height (excluding the control box and drying box, including the size of the adjusting feet); it is made of 316L square tubes with a thickness of more than 1.5mm, which can withstand the weight of the fish tank without deforming; it has three layers of experimental layers, with the bottom being the water distribution and adjustment box, ensuring the maximum utilization of space and facilitating observation and maintenance.
2. The wastewater discharge pipe material is 316L; the inner wall is smooth and shiny, with excellent chemical resistance and not prone to corrosion. It is food-grade and can withstand high temperatures.
3. According to national standards, prepare standard dilution water for the toxicological exposure experiment. This water is used for the preparation of the original water for the experiment. At the same time, adjust the parameters required by the standard to meet the survival conditions of zebrafish; also adjust the pH, conductivity, and dissolved oxygen in the water to meet the survival conditions of zebrafish; the adjustment area is equipped with four salt water tanks and a water quality adjustment tank. Each tank has a volume of no less than 1000 milliliters and is used for preparing the standard water solution.
4. Each layer of the fish tank can be independently set for the dosage ratio. It is equipped with a spiral liquid-injection function to mix the water for breeding and the medication. The dosage amount can be set through the operation interface. The medication bottle can be sealed to prevent cross-contamination; a high-precision pump is provided to meet the requirements of automatic medication. Each row of fish tanks is independently controlled, and the dosage accuracy is ≤ 1%.

5. Equipped with a water bath box, which heats each row of fish tanks without affecting the observation; each row of water bath boxes has inlet and outlet water ports, and the water inflow and outflow are controlled manually. It can be used for adding water and draining water from the water bath boxes after the experiment.
6. After the experiment is completed, the fish tank can automatically drain the water into the wastewater bucket. The waste liquid bucket is transferred without polluting the environment. When the water level reaches the maximum, the drainage stops automatically and an alarm is triggered.
7. Intelligent lighting system, allowing for customizable lighting duration. It can be manually adjusted to change the light intensity according to the actual environment. When turning on or off the lighting, it simulates sunrise and sunset, with a smooth transition of brightness fading in and out.
8. Equipped with a bait storage box. Through the operation interface, the time for adding bait and the feeding amount can be automatically set. When the bait runs out, the interface will give a prompt alarm.
9. Oxygen supply pump: Flow rate of 2.5 liters per minute or more, with one air tube;
10. The drug injection port can be connected to the automatic drug injection pipeline, or it can be easily disassembled to meet the requirements of manual drug addition.
11. The lighting can be adjusted. To avoid interference between the lights, there are also blackout curtains installed.

12. The equipment is equipped with step-like footrests, made of specially designed anti-slip materials, which can meet the needs of different height experimental operations and prevent operators from slipping.
13. At the bottom of the equipment, there are four foam wheels. The height can be adjusted by the knob. These wheels support the base in contact with the ground, providing stable support. When not in contact, the wheel contact area makes it convenient for the equipment to move at any time.
14. The weak current system is made of fire-resistant materials;
15. Meets safety electricity usage requirements and is equipped with an electric leakage circuit breaker;
16. Control Box: Splash-proof control box; Equipped with mechanical switches: electronic switches: photoperiodic lamps, aeration pumps;
17. Industrial-grade panel: Displays system information, online water quality parameters, and 24-hour water quality parameter recorder; The toxicology fish rack is equipped with a human-machine interface. Laboratory personnel can adjust parameters such as raw water preparation, temperature, light, pH, conductivity, dissolved oxygen, and dosage through the human-machine interface.
18. The system includes a set of dissolved oxygen monitor, industrial electrodes, with dissolved oxygen range: 0.00 - 20.00 mg/L ± 0.2% FS; it also includes a set of salinity monitor, industrial electrodes, with salinity range: 1 - 500 ± 1 ppm; pH (acidity and alkalinity) is accurate to two decimal places (e.g. 7.00); temperature is accurate to one decimal place, with an error of ±2℃; conductivity EC: 0 - 2000 us; 3.19 pH, conductivity, dissolved oxygen, and salinity can be set for high and low warning ranges.
