Stakpure RO 20 ED ready mini
The compact for H2O pure type ASTM II + DIN 285
RO ED ready mini is the system of choice when pure water is needed for the complete laboratory supply and space is limited. The system meets international water standards such as ASTM, ISO 3696, CLSI, DIN 285 and is economically maximised by the combination with the continuously self-regenerating electro-deionisation. In addition, the system holds 50 litres of pure water in a 50l storage tank with optional recirculation module for withdrawal. A frequency-controlled pressure and ring line pump can be used to supply downstream end devices and/or ring line systems. Mobile on castors, the system can be
integrated in a 90 cm laboratory base cabinet to save space. The RO ED ready mini system is predestined for the supply of autoclaves or dishwashers and ultrapure water systems in laboratory and medical technology.
