Christ Alpha 1-4 LSCbasic -55°C & Christ Alpha 2-4 LSCbasic -85°C Freeze Dryers

Alpha 1-4 LSCbasic and Alpha 2-4 LSCbasic benchtop freeze dryers are ideal for lyophilizing small to moderate sample volumes for routine lab work. Their compact and tabletop design maximises functionality while conserving benchtop space. The -85°C ice condenser on Alpha 2-4 LSCbasic unit is the perfect choice for samples with a low eutectic point. Both units are equipped with a 4L ice condenser capacity and the LSCbasic touchscreen controller for easy operation. There are multiple configurations to choose from, enabling you to customise the freeze dryer to fit your specific application.
