Acid-Resistant CentriVap Pro Vacuum Concentrators are designed to rapidly concentrate multiple small samples using centrifugal force, vacuum and heat. Components in the vapor path are constructed of corrosion-resistant materials to support concentration of samples containing chemicals such as 0.1 to 1% TFA, hydrochloric acid, acetic acid, hydrobromic acid, ammonium hydroxide and sodium hydroxide. A touch screen interface and integrated software allow for real-time control and display of run parameters, data collection and storage, program development, and diagnostics. As many as 312 samples may be processed at once when utilizing double-stacked rotor arrangement. Sample sizes range from a few microliters up to 50 milliliters. CentriVap Pro Concentrators are also available as one component of CentriVap Pro Concentration Systems.
