III.Functional characteristics analysis
1.Interchangeable design of angle rotor and horizontal rotor
Technical principle:
Angle rotor:The centrifuge tube is fixed at an inclination of 30°-45°.When rotating at high speed,the sample settles along the rotor axis,which is suitable for high-speed and short-time separation(such as DNA extraction,protein precipitation).
Horizontal rotor:The centrifuge tube is suspended in a horizontal position.When rotating,the sample settles in the vertical direction,which is suitable for low-speed and long-time separation(such as cell culture supernatant clarification,blood cell separation).
Advantages:
One machine for multiple uses:By changing the rotor to adapt to different sample types and processing requirements,the equipment procurement cost is reduced.
Flexible operation:The rotor can be replaced in just 30 seconds without the need for tools.
