Magnetic Stirring Tank

Magnetic Stirring Tank | Aseptic, Sealed, Leak-Free Magnetic-Coupled Batching and Mixing Equipment

💡The magnetic stirring tank features a magnetic coupling drive with no mechanical seals. It has a mirror-finished 316L stainless steel tank body, ensuring zero leakage and making it suitable for stirring and mixing in aseptic pharmaceutical applications as well as with flammable, explosive, and toxic materials. It supports CIP cleaning and SIP in-place sterilization.

I. Product Introduction

Magnetic stirrer tanks use a magnetic coupling to transmit power from the motor to the stirrer blade inside the tank; with no mechanical seals, they completely eliminate the risk of leakage. They are particularly suitable for stirring and mixing sterile, high-purity, flammable, explosive, or toxic materials.

II. How It Works

The outer magnet is connected to the motor, and the inner magnet is connected to the stirring shaft; the two are completely separated by a stainless steel isolation sleeve. The motor drives the outer magnet to rotate; the magnetic field penetrates the isolation sleeve to drive the inner magnet to rotate in sync, thereby driving the stirring paddle. The entire process involves no dynamic seals, ensuring zero contact between the material inside the tank and the outside environment.

III. Main Structural Components

✅ Stainless steel tank (SUS316L, mirror-polished)

Made of pharmaceutical-grade 316L stainless steel with a mirror-polished interior surface, it has no hard-to-reach areas and is easy to clean, meeting GMP clean production standards.

✅ Magnetic Coupler (Inner Magnet + Outer Magnet + Isolation Sleeve)

Magnetic steel-isolated, sealed drive system blocks any pathways for material leakage, ensuring a fully sealed operating environment.

✅ Agitators (paddle-type, turbine-type, anchor-type)

A variety of impeller types are available to accommodate materials of different viscosities, delivering excellent mixing and dispersion results.

✅ Jacket/Coil (optional)

Hot and cold media are fed into the tank to achieve precise temperature control of the material inside.

✅ Motors and Variable Frequency Drives

Inverter-based stepless speed control allows for flexible adjustment of the mixing speed according to process requirements.

✅ Temperature and pressure sensors

Collect operating parameters online in real time and monitor the tank environment in real time.

✅ CIP Cleaning Ball

360° spray online cleaning, suitable for automated cleanroom processes.

IV. Core Advantages

✅ Zero leakage: No mechanical seals, making it suitable for sterile, high-pressure, toxic, and flammable processes.

By eliminating the dynamic seal design, we prevent leaks at their source, making it suitable for the production of high-risk media.

✅ Low maintenance: No seal wear; no need to replace mechanical seals.

Reduce the frequency of replacement for wear-prone parts, thereby significantly lowering long-term maintenance and operating costs.

✅ High cleanliness: The isolation sleeve is smooth with no dead corners, making it easy to perform CIP/SIP.

The entire unit can be cleaned and sterilized in situ, in compliance with GMP standards for the production of sterile pharmaceuticals.

✅ Low noise: Magnetic drive eliminates contact friction, ensuring smooth operation.

With its non-contact magnetic drive, the unit produces minimal vibration and low noise.

✅ Explosion-proof option available: Equipped with an explosion-proof motor for use in the preparation of solvents such as alcohol.

The explosion-proof configuration is suitable for batching workshops handling flammable and explosive organic solvents.

V. Typical Use Cases

✅ Aseptic pharmaceutical manufacturing: Preparation of solutions for injectables and lyophilized powders for injection.

Sterile solutions are prepared in a closed system to prevent external contamination.

✅ Biologics: A combination of vaccines and blood products.

Fully enclosed mixing and blending of highly active biological solutions.

✅ Fine Chemicals: Formulation of catalysts and additives (to prevent leakage and contamination).

Production involving the mixing of toxic and irritating chemical raw materials in a sealed environment.

✅ Lithium-ion battery materials: Mixing of electrolytes and slurries.

The flammable and explosive electrolyte for lithium-ion batteries is prepared in a sealed environment.

✅ Fragrances and flavorings: A mixture of volatile components.

Highly volatile flavorings are mixed in a fully sealed system to minimize raw material loss.

VI. Optional Configurations

✅ Double-layer magnetic coupler (higher torque)

High-torque design, suitable for mixing high-viscosity, heavy materials.

✅ Online SIP Sterilization System

Fully automated in-place steam sterilization that meets aseptic production requirements.

✅ Automatic RPM Control

PLC-controlled speed regulation automatically adjusts the rotational speed based on the process curve.

✅ Bottom magnetic stirring (suitable for small vessels)

Bottom-drive design; no shaft protrudes into the tank, ensuring a clean surface with no hard-to-reach areas.

✅ Explosion-proof motor (ExdIIBT4)

Explosion-proof system configuration, designed specifically for Class A explosion-proof workshops.
