In the world of laboratory agitation, not all mixing tasks are created equal. While vortex mixers and orbital shakers excel at small volumes and delicate cultures, certain applications demand the sheer torque and consistent power of an Overhead Stirrer. Since 2012, Labnique has provided researchers, educators and professionals with robust instruments designed to handle the most demanding mixing challenges.
Our collection is curated by a Ph.D.-level scientist to ensure that whether you are working with viscous polymers or large-volume buffers, your agitation is uniform, repeatable, and safe.
Why Choose an Overhead Stirrer?
Overhead stirrers are the workhorses of the lab, offering several advantages over traditional magnetic stirrers:
- High Viscosity Handling: Designed to maintain constant speed even as the resistance of your sample changes.
- Large Volume Capacity: Capable of mixing liters of solution that would overwhelm a standard stirrer.
- Precise Control: Digital interfaces allow for exact RPM settings, crucial for sensitive chemical syntheses.
Featured Solutions: The Labnique Overhead Collection
1. For High-Volume & Industrial Mixing: The 20L Digital Overhead Stirrer
SKU: OHS-20T
Best For: Large scale buffer prep, pilot plant production, and high-viscosity polymers.
If your workflow involves volumes up to 20 Liters, the OHS-20T is the definitive choice. It features an enhanced 200W motor designed to push through the resistance of thick emulsions without stalling.
- Speed: 100–1500 RPM
- Stand: Includes heavy-duty stand for maximum stability.
- Key Advantage: The integrated timing function allows for standardized, unattended mixing protocols.

2. For R&D and Benchtop Versatility: The 5L Digital Overhead Stirrer
Best For: Small batch formulations, educational labs, and daily reagent preparation.
The OHS-5 offers the same professional precision as our larger models but in a footprint optimized for the standard lab bench. It is perfect for researchers who need more torque than a magnetic stirrer can provide but are working with volumes under 5 Liters.
- Speed: 100–1500 RPM
- Stand: Includes a compact stand and platform.
- Key Advantage: High-torque performance in a space-saving design, featuring a corrosion-resistant stainless steel shaft.

Key Applications
- Chemical Synthesis: Ensuring uniform heat distribution and reagent contact in large flasks.
- Cosmetic & Food Science: Homogenizing thick creams, lotions, or food dispersions.
- Wastewater Testing: Facilitating flocculation and sedimentation studies.
- Polymer Research: Mixing high-molecular-weight solutions that require high torque.
Essential Features to Look For
When shopping for an overhead stirrer, consider these Labnique-standard features:
- Brushless DC Motors: For quiet, maintenance-free operation and long service life.
- Safety Protection: Overload and over-temperature protection to prevent motor damage during long runs.
- Through-Shaft Design: Allows for easy adjustment of the stirring impeller height without moving the entire motor.
Final Notes
