Question

The disk centrifuge is the type of centrifuge used most often for bio separations due to its
A.continuous operation
B. lesser cost
C. higher speed
D. ease in operation

Answer 1

hey

the answer is C ..higher speed

Answer 2

Answer:

The disk centrifuge is used most often because of its lesser cost.

Option B

Explanation:

It separates particles by size with the help of centrifugal sedimentation in a liquid medium. It is stabilized by a slight density gradient.  

The sedimentation is clear within the rotating disc.

When the particles reach the outer edge of the disc. They either block or scatter the beam of light that passes through the disc.  

The change in the intensity of light is continuously recorded.

It is converted by the software into a particle size distribution.

Advantages:

• Highly sensitive.

• Much faster analysis.
• Continuous centrifugation.
• Measurement accuracy.
• Automatic density gradient for accurate filling of the centrifuge chamber.
• It is often used because it is of lesser cost.

Hence, the disk centrifuge is the most used centrifuge used for particles separation as it is lesser cost.
