OverviewThe LevMixer system is specifically designed to fulfill the needs of the bioprocess industry. This system is a mobile, flexible mixing system that allows efficient and reproducible single-use mixing of a wide range of volumes in a broad series of applications ranging from buffer preparation to final formulation. The LevMixer hardware has been engineered for use with Pall single-use systems (SUS) in cGMP certified cleanrooms.

The LevMixer system consists of an interchangeable superconducting drive unit and proprietary levitating impeller-based single-use mixing system fitted into either plastic tanks located on a trolley or stainless steel tanks. Once charged and coupled with the single-use system, the superconducting drive unit induces levitation and rotation of the impeller (Figure 1) resulting in effective mixing action inside a closed mixing system. Coupling of the impeller with the drive motor requires no dynamic seals or shaft penetration inside the single-use system. The drive motor is enclosed on a portable cart that can be easily disconnected from the single-use system and reconnected to another mixing system, allowing mixing in multiple single-use mixing systems of various sizes with a single drive unit.

The LevMixer system includes a real-time reading of the impeller speed and an process monitoring/alert capability. In case of any process disruption, the user is alerted. End users may access a detailed activity report during on-going applications to monitor the mixer either on site, or remotely from a different location.

Additionally, the mixer may either be controlled on site or remotely, based on user preference. When operating onsite, users will benefit from an easy-to-use touchscreen PLC that features access to the mixing recipe in use.

The LevMixer system utilizes disposable mixing biocontainers made from Allegro™ film. It is animal derived component free (ADCF) and complies fully with USP Class VI requirements.

Principle of OperationThe mixing technology of the LevMixer system is based on non-contact magnetic coupling between conventional permanent magnets in the impeller and superconducting material in the drive (Figure 3). Superconducting material has the ability to trap the magnetic field generated by the permanent magnets and “lock the magnetic field in memory” in an equilibrium position. The trapped magnetic field behaves like mechanical springs; if the magnet is moved up, down or sideways by outside forces (e.g., gravity or angular torque) it will tend to be pulled back to an equilibrium position. The peculiar nature of magnet- superconductor interaction ties the two bodies together resulting in a very stable magnetic coupling with finite equilibrium separation. This system is housed in a universal drive unit (Figure 4).
