The Labconco CentriVap benchtop vacuum concentrator is the perfect unit for small samples, allowing you to collect as small as a few microliters of your sample. The concentrator uses gentle centrifugal force, heat, and vacuum to quickly evaporate solvents from up to 148 samples. Easily change out the rotor to process samples from a few microliters up to 25 mL; order separately. The microprocessor controls heat and a speed of 1725 rpm to provide reliable results. The 300 W heater achieves a temperature from ambient to 100?C. Models with optional heat boost feature an additional heater for faster evaporation. Control time and temperature using the easy-to-use keyboard. Store up to nine programs to quickly run different types of samples. Convenient quick-start buttons let you initiate programs with a single push of a button. In addition, you can alter the temperature and the time parameters even while a program is in process. Models with a glass lid let you easily view samples and offer protection against etching caused by solvents. Order vacuum pump and sample containers separately. Quickly process multiple samples to recover as small as a few microliters! Recover as small as a few microliters of your sample Create up to nine stored programs that can be altered while in progress Accommodates a variety of rotors to process up to 148 samples Automatic vacuum bleed valve releases vacuum when rotor stops to prevent loss of sample
