Good news! Winning supplier: Guangzhou MingSheng Testing Equipment Co., Ltd. Congratulations to our company on laying a solid foundation in the medical device field with the walk-in environmental test chamber. The walk-in constant temperature and humidity test room and the series of high/low temperature test chambers and high temperature test chambers serve medical device centers such as the Shandong Medical Testing Center, the Medical Device Research Center of South China University of Technology, and the Zhejiang Institute for Medical Device Inspection and Research.
The Shenzhen Medical Device Testing Center is a government statutory professional institution that carries out quality supervision and inspection of drugs and scientific research in accordance with the law. Its inspection scope covers six major categories — drugs, medical devices, health foods, cosmetics, pharmaceutical packaging materials, and clean rooms — with over a thousand inspectable items. It is a laboratory authorized by the state to conduct registration testing of traditional Chinese medicines for the Hong Kong and Macao regions. Located in the Shenzhen High-tech Park, the new drug testing building has a total floor area of 15,000 m² and houses physicochemical, instrument, electronic and light-protected laboratories. The animal experiment and
microbiology/cell testing clean laboratories feature display and control of temperature, humidity, exhaust and pressure differential, adopting the currently advanced BA and VAV two-level automatic control technology, with advanced facilities and laboratory environments. The center has four functional departments including quality assurance, informatization and equipment support, and seven professional technical departments covering drugs, health foods and cosmetics, analytical testing research, medical devices, and pharmaceutical packaging materials.
Main performance indicators of the walk-in environmental test chamber:
1. Temperature range: (-40~+100)°C;
2. Temperature fluctuation: ≤±0.5°C;
3. Temperature uniformity: ≤2.0°C;
4. Temperature deviation: ≤±2.0°C;
5. Humidity range: 20% to 98% within ambient temperature range (15~85)°C
6. Humidity fluctuation: ≤±3%RH
7. Humidity deviation: ≤±3%RH (when humidity >75%RH); ≤±5%RH (when humidity ≤75%RH)
8. Temperature change rate:
Heating rate: (-40~+100)°C, average rate over the whole range 1.0 K/min; (no heat load)
Cooling rate: (+100~-40)°C, average rate over the whole range 1.0 K/min; (no heat load)
9. The compressor's cooling capacity output during the test shall be continuously adjustable, equipped with cold-end PID automatic regulation technology (i.e., during constant-rate cooling and low-temperature soaking, the cooling output is adjusted by cold-end PID to reach temperature balance, with the electric heaters not working, saving operating energy to the maximum extent); electronic pressure sensors shall be installed at the compressor suction and discharge ports to read the high-pressure and low-pressure values in real time.
