Many applications within the field of life sciences need vacuum.
Experienced users know that the efficiency of a vacuum concentrator or vacuum oven depends very strongly on selecting the appropriate vacuum system. Modern vacuum systems are capable of achieving efficient, user friendly, economic and environmental friendly generation of vacuum. Oil-free, chemically resistant diaphragm pumps have been well proven here.
The Vacuubrand three stage chemistry diaphragm pump MD 4C achieves a final vacuum of 2 mbar. Even at 10 mbar the MD 4C still achieves more than 60 per cent of its full pumping speed for the duration of the process. The pump is also available as a complete system with vacuum regulation and solvent recovery. Synchro versions offer the possibility for simultaneous operation of two separate vacuum systems and thus are not only particularly space saving, but also reduce the costs.
Applications demanding precise and simple vacuum regulation can be optimised with the new VARIO pumping units from Vacuubrand. Precise single-point vacuum control without the need for programming and with automatic adjustment of the vacuum, which reduce process times by over 30 per cent, have clear advantages.
Also for frequent vacuum aspiration of liquids in biochemistry, biology and medicine a pollution free and user-friendly diaphragm pump system can be used. The BioChem VacuuCenter BVC 21 from Vacuubrand consists of an efficient diaphragm pump, an autoclavable collection bottle and a versatile hand control for a professional, comfortable operation using an automatic vacuum switch to avoid the need for foot pedal operation.
