Concentration &Lyophilization both are available with the liquid samples
When you want to concentrate & freeze dry with small quantity of liquid samples quickly , you can put the samples in the micro tubes as liquid.

The Operon Speed vacuum centrifugal concentrator (SVQ) is designed for preparation with a high speedy and maximum recovery of DNA, RNA , Protein , Peptides , Amino-acids , Enzymes , for analysis by IR , UV and Electrophoresis.
The Gravitational force prevents bumping , foaming and sputtering of the solution so that virtually 99% of the samples concentrated and recovered .
Rotor is driven magnetically.
Motor is located in the lower section and transmit the power through a magnetic coupling.
