Ensure secure power transmission and airtight seal integrity for your mixing applications with professional laboratory stirrer heads. This specialized range features high-performance Bohlender magnetic stirrer heads for vacuum-tight operations and IKA keyless chucks for rapid tool changes. As a critical component category within our stirring, shaking, and mixing and overhead stirrers ecosystems, these heads connect your stirring drive to the sample with precision and safety.
Why Choose Professional Laboratory Stirrer Heads?
Our curated collection of magnetic and mechanical stirrer heads is designed for high-torque laboratory environments:
- Vacuum-Tight Magnetic Coupling: We stock Bohlender SG-Magnetic Stirrer Heads in various NS joint sizes (19/26 to 45/40) for gas-tight stirring under vacuum or pressure.
- Rapid Tool Interchanges: Utilize IKA Keyless Chucks (R 60 and R 60.1) with clamping ranges from 0.5 mm to 10 mm for quick, manual installation of stirring shafts.
- Vibration-Damping Couplings: Select Buddeberg FK 1 Flexible Couplings to compensate for slight misalignments between the stirrer motor and the shaft, reducing mechanical stress.
- Advanced Material Compatibility: Choose Bohlender P-MRK magnetic stirrer heads, engineered to provide high-torque transmission for medium to high-viscosity media.
LabFriend supplies laboratory stirrer heads from world-class leaders in stirring and coupling technology:
- Bohlender: The specialist in high-performance fluoropolymer labware, providing industry-standard magnetic stirrer heads for airtight applications.

- Chemical Sorbents: Maintain a clean workstation during assembly and liquid transfer with Brady Spill Kits.
Unsure if your vacuum setup requires a Bohlender NS 29/32 magnetic head or the flexibility of an IKA R 60 keyless chuck? Our team provides local technical support to help you find the correct stirrer head solution with fast shipping and competitive pricing.
Frequently Asked Questions
1. What is the benefit of a magnetic stirrer head over a standard chuck?
Magnetic stirrer heads, like the Bohlender SG series, allow for completely gas-tight and vacuum-tight stirring by using magnetic coupling to transfer motion through a sealed joint.
2. How do I choose the correct NS joint size for my stirrer head?
The NS joint size (e.g., 29/32 or 45/40) must match the ground glass joint of your reaction vessel to ensure a secure, airtight fit.
3. What does a flexible coupling like the Buddeberg FK 1 do?
A flexible coupling acts as a buffer between the stirrer motor and the shaft, absorbing vibrations and compensating for small alignment errors that could otherwise damage the motor or break the glass vessel.
4. Are IKA keyless chucks compatible with all stirring shafts?
IKA keyless chucks are designed for a specific clamping range (e.g., 0.5 to 10 mm); as long as your stirring shaft diameter falls within that range, it can be securely fastened without tools.
