Sterile viscous liquids Ophtalmic gels Cosmetics Hyaluronic acids

Magnetic Coupled Top-Driven Stirrers find application whenever the process doesn't allow for bottom-driven units to be used :

a) In some sterile production applications, large vessels with their respective large bottom drain valve clusters are used. Such equipment cannot be combined with bottom-driven magnetic agitators.

b) Many processes need strong agitation forces for viscous liquids. These are obtained with a strong energy input into the system, where physically limited classic magnetic drives fail.
MCS1 meets both above mentioned challenges and adds safety in process sterility by eliminating the use of the delicate rotating mechanical seal. Homogeneous API concentration prior drain is reached, even for high viscosities. In extreme cases, Rütten sterile vessels with heated double jacket may further boost the process efficiency. Rütten guarantees a rotation speed precision of > 99%, ensuring perfectly mastered process conditions. The stator body is completely closed, facilitating CIP/SIP cleaning procedures.
