Eppendorf Vacufuge Concentrator 0 Rotors Rotor 72 x 0.5 Ml 8 x 31 mm Microcentrifuge Tubes stackable. 5ml rotors which can be stacked for 96 x 1.5ml or 144 x 0.5mL microcentrifuge tubes. The Eppendorf Vacufuge Concentrator is a space-saving centrifuge which eliminates sample loss during evaporation. The Eppendorf Vacufuge 022822080 works by creating a vacuum by simply drawing the lid down allowing agar or other liquids to dry. As the concentrator draws the liquid across a membrane a vacuum is created and the lid is sealed. An agar weighted down ensures constant centering of the agar without loss of DNA or RNA sample due to evaporation. The centrifuge rotor has a weighted and sealed center which prevents bursting of the rotors due to bumping or alcohol build-up. Following evaporation the lid is released and the centrifuge is allowed to run without pumping. Following use the Eppendorf Vacufuge 022822080 clear lid which allows sample viewing and seals the chamber without the use of grease.
