Rod Type
For Standard Magnetic Mixing
Reference impeller:
Flat blade paddle
Rod-shaped designs generate a primarily radial flow pattern by pushing fluid outward from the center. This classical stirring motion is suitable for low-viscosity liquid mixing and simple dissolution or suspension tasks in routine laboratory settings.
Key Benefits:
-
Reliable Radial Flow: effective for general-purpose mixing
-
Material Flexibility: offered in amorphous (cost-effective) and crystallized (higher resistance) PEN for application-specific needs
-
Stable Performance: 30 mm and 40 mm sizes include pivot points to reduce decoupling
-
Standard Compatibility: fits most lab vessels and workflows
Applications:
-
Buffer and Reagent Preparation: dissolves powders and solutes uniformly
-
Aqueous Solutions: maintains suspension of particles in low-viscosity fluids
-
Routine Lab Work: ideal for standardized protocols requiring gentle agitation
-
Analytical Sample Prep: ensures homogeneity in test samples without shear damage

Innovation 2
Rod-Shaped Design:
The SCA series is capable of generating a stable radial flow field. During rotation, liquid is pushed horizontally outward from the center, guided upward along the vessel wall, and then returns to the bottom of the central region, forming a well‑defined mixing circulation. Strong magnetic coupling, combined with a specially designed pivot point, effectively stabilizes the stir bar and prevents decoupling, ensuring smooth, stable operation even at high speeds.

▲ Fluid flow pattern of FBP and SCA20
Inspired by the design of the FBP impeller, the SCA series stir bars were developed to address the common laboratory issue of decoupling while delivering efficient and stable mixing. Capable of generating a stable radial flow field, the SCA combines strong magnetic coupling, achieved with SmCo rare‑earth magnets that are four times stronger than standard magnets, with a specially designed positioning bump to ensure exceptional stability and prevent decoupling even at high rotational speeds. Available in sizes from 11 mm to 40 mm, with custom sizing options.
