Standard Operating Procedure for Yingtai Centrifugal Concentrator: Seven Steps To Master Correct Usage!

Standard Operating Procedure for Yingtai Centrifugal Concentrator: Seven Steps to Master Correct Usage!  

1. Power-On Preparation  

   - Check if the cold trap is completely defrosted and wipe it clean with a soft cloth.  

   - Inspect the chamber to ensure it is clean and dry.  

   - Verify that the vacuum oil level is between MAX-MIN and that the oil is clear and transparent.  

2. Pre-Cool the Cold Trap  

   - Turn on the cold trap power (if equipped) and pre-cool for at least 10-15 minutes to reach the working temperature.  

3. Parameter Setting  

   - Set the temperature parameters.  

   - Set the run time.  

   - Adjust vacuum control (based on solvent type).  

4. Sample Loading  

   - Place the sample tubes evenly on the rotor to ensure symmetrical balance.  

   - Do not exceed half of the tube’s capacity.  

5. Start Operation  

   - Close the lid and press the "Run" button to start.  

   - The vacuum pump will activate once the rotor reaches operating speed.  

6. Run Monitoring  

   - Avoid over-drying (DNA may become difficult to re-dissolve if dried completely). It is recommended to stop when the sample is slightly moist.  

7. Ending the Operation  

   - After the run, wait until the rotor comes to a complete stop before opening the lid and removing the samples.  

   - Clean the instrument surface and wipe away any water or frost on the cold trap.  

Special Notes:  

   - Never open the lid while the rotor is spinning.  

   - Do not concentrate large volumes of organic solvent samples (pre-treat with rotary evaporation first).  

   - Do not tilt the device during operation.  

As a high-efficiency concentration tool in modern laboratories, selecting the right model and operating it correctly is crucial. Whether for high-throughput research demanding maximum efficiency or cost-effective teaching experiments, there is always a centrifugal concentrator suited to your lab’s needs.
