These chemistry vacuum systems and chemistry pumping units are available in a full range of volume flow rates and ultimate vacuum options. For every vacuum range the most appropriate vacuum pump is used as base. Complete vacuum systems and pumping units offer the advantage of a ready for operation assembly and an optimal configuration with useful accessories.

• Particularly efficient are the vacuum systems and pumping units for simultaneous handling of 2 autonomous vacuum processes. Effective non-return valves protect against reciprocal impact.
• High pump performance even in parallel operation.
• Compact design, space-saving and high flexibility.
• Plain surfaces for easy cleaning.
• High user comfort by well proven configurations.
• High vapour tolerance for water and solvents.
• Low noise level.
• Reasonable ultimate vacuum even with open gas ballast valve.
• VACUU·SELECT controls all common vacuum processes in chemistry labs.
• Predefined applications for quick, save time and guarantee reproducible results.
