Biotech DEGASi Preparative Stand Alone Degasser 2-channel 5.3ml Systec AF, 15 ml/min per channel


Our Preparative Stand Alone Vacuum Degasser Systems are specifically designed for HPLC and other fluidic systems. The DEGASi PREP series is designed for flowrates from 15-50ml/min per channel. The system removes dissolved gases from the mobile phases to reduce retention time shifts and improve baseline stability, as the pump will work much more reliable. Removing dissolved gasses eliminates bubbles before they occur and removes oxygen which can interfere with UV detection methods. The system is available with 2 channels.
