Standard operating procedure for centrifugal concentrator: seven steps to master correct usage!
Standard operating procedure for centrifugal concentrator: seven steps to master correct usage!
1. Start-up preparation
· Check whether the cold trap is completely defrosted and wipe it clean with a soft cloth
· Check whether the cavity is clean and keep the cavity dry· Check whether the vacuum oil level is between max-min and whether the oil is clear and transparent
2. Precool the cold trap
Turn on the cold trap power (if configured), precool for at least 10-15 minutes, so that the temperature of the cold trap reaches the working temperature
3. Parameter setting
· Set temperature parameters
· Set running time
· Set vacuum control (adjust according to solvent type)
4. Sample loading
· Balance the sample tube on the rotor to ensure symmetrical balance
· The sample volume does not exceed half of the tube volume
5. Start Run
· Close the cover and press the "Run" button to start
· After the rotor reaches the operating speed, the vacuum pump starts
6. Run monitoring
Avoid over-drying (DNA is difficult to re-dissolve after drying), it is recommended to stop when the concentration is slightly moist
7. End the operation
· After the operation, wait for the rotor to stop completely before opening the cover and taking out the sample
· Clean the surface of the instrument and wipe off the water and frost on the surface of the cold trap
Special attention:
· It is strictly forbidden to open the cover when the rotor is rotating
· It is forbidden to concentrate a large amount of organic solvent samples (must be pre-treated with rotary evaporation first)
· The equipment cannot be tilted when the machine is running
Centrifugal concentrator: As an efficient concentrator in modern laboratories, it is crucial to choose the right model and operate it correctly.
Whether it is a high-throughput research that pursues extreme efficiency or a teaching experiment that focuses on economy and practicality,
there is always a centrifugal concentrator that suits your laboratory needs.
