Headplate on SSS vessel with sealing membrane Vibrating Agitator
Rotating agitators use either a mechanical seal or a magnetic coupling. Mechanical seals are subjected to catastrophic failure, are difficult to keep sterile and are hard to clean. Typical vessel-mounted magnetic couplings are also hard to clean. Additionally are baffles required to avoid Vortex-formation which are generating shear-force, which has to be avoid with use of sensitive products.
Vibrating mixers are driven by vibrating motor above the vessel. The vibrating shaft transmits its force to a perforated mixing plate fixed at the shaft end. As the plate vibrates up and down, liquid jets are formed by the conical perforations in the mixing plate. The result is a gentle and effective mixing (Bernoulli effect). The vibrating shaft is perfectly sealed with a simple teflon-silicone membrane. Vibrating mixers are suitable for being used under pressure or vacuum or at atmospheric pressure for:
● Mixing of low viscosity fluids
● Suspension of solids liquids
Emulsification of immiscible
© Your Benefits
● Absolute sterility assurance
● Autoclavable in place if the actuator is removed
● Easily validated to ensure cGMP compliance
● No rotating seals
● Low investment cost in comparison with the current systems
● New measurement and control electronics ensure constant vibration
● Can be used for tanks from 20 to 10,000 litres
● Low shear stress transmitted to the fluid in comparison with the commonly used stirrers
