A range of centrifugal vacuum concentrators that has the capacity or capability in eradicating the organic solvents and water from the different formats of samples involves vials, tubes and microplates is known to be miVac centrifugal concentrator from the Genevac. It is also utilized for freezing the dry samples that are normally aqueous. The systems of the miVac are suitable to be utilized with the various types of solvents from the volatile organic kinds through to the water and various solvents of the medium boiling point. The choice of medium or high vacuum pump and a dedicated system of DNA with a pump that is built in are provided. The rotors are picked based on the type of sample formats in the utilization. And can incorporate deep as well as shallow well microplates, tubes, and glass vials. The rotors chosen can be simply replaceable. While utilizing the high vacuum pump, the specimens might be freeze dried using the accessory kit of freeze drying, either in the pre-frozen f
