Biotech DEGASi Prep+ Stand Alone, Preparative Degasser, 4-channel 20ml Systec AF, 100 ml/min per channel


Degasi Prep+ 4 channels uses a revolutionary new technology that makes it possible to degass organic solutions with higher flows in a cost effective manner. That means you can get increased capacity at a lower price. Degasi Prep+ is a perfect choice for efficient degassing of many types of liquids at high flow rates, up to 75-100 mL /min per chamber. Not to be used with hexane, heptane and iso-octane. The system removes dissolved gases from the mobile phases to reduce retention time shifts and improve baseline stability. Removing dissolved gasses eliminates bubbles before they occur and removes oxygen which can interfere with UV detection methods. The system is available with 1,2 and 4 channel systems.
