Introduction
The sucrose preference test is commonly used to assess depression, addiction in rodents. A hallmark of depressive-like states is anhedonia, and compared with normal animals, model animals typically show a significantly reduced preference for sucrose solution. The system uses micro-current detection to accurately record the animals' drinking episodes and drinking duration.
The system supports multi-channel testing, with each host capable of connecting up to 4 home cages simultaneously, allowing testing of up to 4 animals at the same time.

Features
Automatic detection: The entire experimental process is automated, and data are recorded automatically, eliminating subjective errors associated with manual observation and counting, as well as disturbances to the animals that could introduce experimental variability.
High-temperature sterilization compatible: The cage are made of PSU (polysulfone) material, which withstands repeated autoclaving at temperatures up to 160 °C and remains distortion‑free for up to 200 sterilization cycles. This prevents cross‑contamination between different batches of animals and ensures animal safety.
Detailed results: The system records comprehensive data for each drinking bout, including the type of fluid consumed, start time, end time, and duration. Built‑in statistical functions automatically calculate the total number of drinking episodes and total drinking time for each of the two water bottles.

Application Fields
The sucrose preference test is primarily used for evaluating behaviors related to depression and addiction, in neuroscience, pharmacology, and toxicology research – for example, studies on the neural mechanisms of depression, screening of antidepressant drugs, and research on drug addiction.Specifications:
