Eppendorf Vacufuge Concentrator 0 Rotors Rotor 16 x 6.5 Ml 20 x 42 mm Or 10 Ml 20 x 55 mm Round-Bottom Tubes. With a vacuum release shortly after reaching equilibrium DNA and RNA remain in a "vacuum state" until they are dried to a "solidus" state. They can then be diluted in water a reducing agent or a proteinase-resistant organic solvent. To withstand the centrifugal force necessary for concentrating difficult or viscous liquids without a liquid-handling device the Vacufuge Concentrator was designed with a thicker brush and smaller rotor than most centrifuges. Because of this opening and closing the Vacufuge Concentrator is quick and easy. There is no need to thread tubes or manipulate the rotor shafts since they are friction fit. And since the Vacufuge Concentrator has a motorless drive there is no risk of overheating. Additionally a leak-proof center cone with two sealing rings and a hinged lid seals the vacuum line leaks very rarely. The Eppendorf Vacufuge Concentrator has a leak-proof center vacuum seal.
