Nowadays, low-temperature test chambers are increasingly used across various industries—not just for research and experiments but also for testing many everyday products. Today, we’ll share some important precautions. Only by using the equipment correctly can accurate results be obtained, and only by handling it with care can it serve us better.

1. Sample Placement Can Directly Affect Test Results
Many experienced users know that these chambers rely on air circulation, making sample placement crucial. The number of samples also matters—avoid overloading the chamber. Ideally, samples should occupy no more than one-third of the chamber’s space and be placed in the center. Proper positioning ensures smooth airflow and prevents interference with the test results.

2. Distinguish Sample Types to Avoid Adverse Outcomes
When testing samples, be aware that flammable, explosive, or corrosive substances must not be used. Additionally, if testing liquid samples (e.g., water), ensure they are securely contained to prevent spills.

3. Key Precautions for Using Low-Temperature Test Chambers
Immediately stop use if the equipment comes into contact with water to avoid electric leakage, electric shock, or even fire hazards.
After use, avoid wiping the chamber with wet cloths, alcohol, or organic solvents—only use a dry cloth for cleaning.
Do not open the chamber door during testing unless absolutely necessary, as this can affect temperature stability.
Ensure proper ventilation around the chamber and inspect immediately if unusual noises occur.
Regularly calibrate the instrument to maintain accuracy and proper functionality.
Always follow standard operating procedures in the lab to prevent equipment damage and, more importantly, personal injury.
By using and maintaining low-temperature test chambers correctly, we can prevent accidents and extend the equipment’s lifespan. Stay vigilant and operate responsibly!
