Інструкція з експлуатації

1. Попереднє охолодження: Turn on the freeze dryer. Allow the collector coil to reach its operating temperature of -50°C (-58°F). This may take approximately 30-60 minutes. Monitor the temperature on the display.
2. SampПідготовка: Підготуйте свій samples for lyophilization. Samples should be pre-frozen and placed in appropriate freeze-drying flasks or trays.
3. Завантаження Samples: Once the collector is at temperature, carefully place the pre-frozen samples into the drying accessories connected to the unit. Ensure the acrylic lid is securely seated.
4. Initiating Vacuum: Turn on the vacuum pump. The display will show the vacuum level. The system will begin to pull a vacuum, and the freeze-drying process will commence.
5. Моніторинг: Continuously monitor the collector temperature and vacuum level throughout the drying cycle. The vacuum level should stabilize at a low pressure (e.g., 0.132 mBar as shown in the image).
6. Завершення: The drying process is complete when all moisture has been removed from the samples. This can be determined by observing the samples or by monitoring the vacuum level (a stable, low vacuum indicates drying is complete).
7. Breaking Vacuum: Before removing samples, turn off the vacuum pump. Slowly introduce air into the system to break the vacuum. Do not open the system abruptly.
8. Sample Removal: Carefully remove the dried sampлес.
