The ZLNS-1 Laboratory Vacuum Centrifugal Concentrator is an economical solution designed for efficient DNA RNA and protein sample purification.
This compact unit features an integrated pump system, providing reliable performance for various laboratory applications.
The solvent is evaporated by a combination of centrifugal force, heating, and vacuum provided by a built-in vacuum pump, thereby achieving sample concentration.
Built-in vacuum pump system eliminates the need for external equipment
A vacuum pump is used to bring the system into a dry vacuum state, thereby lowering the boiling point of the solvent and accelerating its evaporation rate.
Suitable for concentration of protein, drugs, metabolites and enzymes. Used for solvent removal of DNA, RNA and nucleoside synthetic samples.
