Achieve optimal axial, radial, or high-shear flow with professional laboratory stirrers. This specialized range features high-performance tools from IKA, including Propeller Stirrers (R 1342, R 1345), Paddle Stirrers (R 1376), and Dissolver Stirrers (R 1303) for intensive mixing. As a critical category within our stirring, shaking, and mixing and overhead stirrers ecosystems, these stirring shafts and rotors are engineered to handle diverse viscosities and vessel geometries.
Why Choose Professional Laboratory Stirrers?
Our curated collection of stirring tools is designed for mechanical efficiency and chemical resistance:
- Axial Flow Propellers: We stock IKA 4-Bladed Propeller Stirrers (R 1342 and R 1345) for drawing material from the top to the bottom with minimal shearing.
- High-Shear Dissolvers: Utilize IKA Dissolver Stirrers (R 1303) for radial flow and high turbulence, ideal for breaking down particles and intensive mixing at medium to high speeds.
- Tangential Flow Paddles: Select IKA Paddle Stirrers (R 1376) for gentle mixing at low speeds across the entire vessel diameter.
- Specialized Stirring Rotors: Choose Bohlender Crescent Shaped PTFE Rotors or Heidolph inoJET systems for specific chemical compatibility or specialized flow requirements.
LabFriend supplies laboratory stirrers from world-class leaders in fluid mixing technology:
- IKA: The industry standard for stirring tools, offering a comprehensive range of propeller, paddle, and dissolver shafts for the Eurostar series.
- Heidolph: Specialist in premium mixing, providing the innovative inoJET stirring system for high-viscosity applications.
- Bohlender: Expert in fluoropolymer labware, offering PTFE-coated stirrer rotors for maximum chemical inertness.

Selecting the correct stirring geometry is vital for process efficiency; to further enhance your laboratory's mixing and safety, we recommend exploring these related categories:
- Overhead Stirring Instruments: Power your stirring tools with high-torque IKA Eurostar digital drives.
- Laboratory Stirrer Heads: Ensure secure attachment with IKA Keyless Chucks or Bohlender Magnetic Heads.
- Waste Bins: Safely dispose of used chemical consumables and contaminated tools in B. Braun Medibox containers.
- Chemical Sorbents: Manage accidental spills during liquid transfer with Brady Spill Kits.
Unsure if your high-viscosity sample requires an IKA Dissolver R 1303 or a Heidolph inoJET system? Our team provides local technical support to help you find the correct stirring tool with fast shipping and competitive pricing.
Frequently Asked Questions
1. When should I use a propeller stirrer like the R 1342?
Propeller stirrers are best for axial flow, drawing material from top to bottom; they are ideal for low to medium viscosity samples that require rapid homogenization with low shear.
2. What is the benefit of a dissolver stirrer?
Dissolver stirrers (e.g., IKA R 1303) create high radial flow and turbulence, which is necessary for intensive mixing, dispersing particles, and breaking up agglomerates.
3. Why choose a PTFE-coated stirrer rotor?
PTFE rotors from Bohlender are highly recommended when stirring aggressive chemicals or high-purity media where stainless steel might corrode or introduce contaminants.
4. Are these stirring tools compatible with any overhead stirrer?
Most of these tools feature standard shaft diameters (e.g., 8 mm or 10 mm) compatible with keyless chucks; however, you should always verify the chuck capacity of your specific drive unit.
