Product Operate Guide


Equipment Start-Up and Operation:

1. Navigate to the "System Menu" → "Operation Screen" and switch the 'Compressor' to "On."

2. After pre-freezing, place the material inside the drying chamber. Then, in the "Operation Screen," switch 'Vacuum Pump' and 'Vacuum Gauge' to "On."

3. Fully open the inlet/exhaust valve and wait for the chamber and cold trap to return to atmospheric pressure before removing and sealing the material. During shutdown, first re-inflate, then turn off the vacuum pump to prevent oil backflow, which could contaminate the samples.

4. Click the "Defrost" button; the defrosting process takes 30 minutes. Allow all ice in the cold trap to melt. Keep the drain valve open during this process, and it's recommended to place a container below the drain valve to collect the defrost water.

These operational steps facilitate a smooth start-up and operation of the equipment, ensuring a seamless freeze-drying process.

FAQ


1. Why does the freeze dryer make noise during operation?

The freeze dryer involves mechanical components such as compressors and vacuum pumps during operation, which can generate some noise. This is a normal occurrence. Ensuring that the equipment is installed on a stable surface can help reduce noise transmission.


2. How should I maintain and clean the bell-jar tabletop freeze dryer?

Regular cleaning and maintenance of the freeze dryer are crucial. Cleaning should include components such as the freeze-drying chamber, cold trap, piping, and observation window. Use appropriate cleaning agents and methods following the manufacturer's maintenance guidelines. Periodically replace filters and gaskets to ensure equipment performance and hygiene.


3. What should I do if the vacuum level of the freeze dryer decreases?

If the vacuum level of the freeze dryer drops, first check for tight seals and connections. If no leaks are found, you may need to change the vacuum pump oil or inspect other components of the vacuum system. Regular maintenance of the vacuum system is recommended to ensure proper operation.


4. Why do my samples crystallize during the freeze-drying process?

Crystallization may occur if certain components in your samples precipitate during the freeze-drying process. To avoid this, you can adjust freeze-drying parameters such as cold trap temperature and sublimation rate to accommodate the specific requirements of different samples.


5. How do I choose the right bell-jar tabletop freeze dryer?

Selecting the appropriate freeze dryer involves considering factors such as sample type, capacity requirements, freeze-drying speed, operational complexity, and budget. Collaborate with the manufacturer or supplier to gain a detailed understanding of the specifications and performance of various models to choose the freeze dryer model that best suits your application.
