Labtron Overhead Stirrer is specialized to agitate larger volume liquids. Their motors provide 50rpm to 6000rpm speed ensuring uniform mixing throughout process. They include various types of blades, optimized for different viscosities and fluid types. Their safety features include automatic shut-off in case of overload or malfunction. Our Overhead Stirrer is used for blending sauces in food industry, creams and lotion in cosmetics and dispersion of pigments.








The Overhead Stirrer LOSR-E12 integrates overload cut-off protection that automatically halts the motor during excessive torque or electrical stress. Our overhead stirrer prevents overheating during continuous operation by regulating internal temperature through controlled circuitry. This mechanism ensures safe stirring of viscous or reactive substances over long durations. Its stable base reduces the risk of tipping or vibration during high-speed use. The sealed housing keeps the motor components protected from dust or accidental spillage. Safety indicators on the display panel alert the user before critical thresholds are reached. Our overhead stirrer's brushless motor design minimizes internal friction, lowering the likelihood of mechanical wear. These combined features make it dependable for environments demanding extended, uninterrupted stirring operations.
The Overhead Stirrer LOSR-E12 comes with a self-locking chuck that prevents shaft slippage during viscous or high-resistance mixing. Our overhead stirrer delivers consistent torque using a brushless DC motor that maintains uniform rotation under varying loads. Its digital control system stabilizes speed even when resistance changes mid-process. The robust construction reduces mechanical flexing, ensuring the shaft remains centered during heavy-duty operation. Our overhead stirrer supports stirring of dense slurries, pastes, and polymer solutions without lagging performance. Adjustable clamps secure the vessel and shaft at fixed heights, reducing the impact of vibration. It enables reproducible results when working with high-viscosity materials over repeated cycles. The unit remains balanced throughout the torque range, reducing wear on coupling components.
The Overhead Stirrer LOSR-E12 is well-suited for shared laboratory environments where multiple users access the same system. Our overhead stirrer offers RS232 connectivity that enables remote monitoring and data logging during experiments. It supports digital speed display, which simplifies tracking for supervisors managing concurrent operations. The sturdy frame design withstands frequent handling and repositioning in teaching or collaborative labs. Our overhead stirrer includes quick-fit assembly, reducing time spent during instrument setup between users. Its consistent torque output makes it reliable for reproducible results across different researchers and tasks. Maintenance-free motor function minimizes downtime, allowing continuous availability for scheduled experiments. The clear interface enhances usability even for less experienced operators rotating between stations.
The Overhead Stirrer LOSR-E12 supports a chuck diameter range from 0.5 to 10 mm, accommodating various shaft sizes used in standard labware. Our overhead stirrer offers an adjustable vertical arm that allows height customization for different beaker or flask sizes. Its versatile clamp system secures both the stirring rod and vessel to prevent wobble during operation. The wide base adds balance when positioned over tall containers or narrow-necked glassware. Our overhead stirrer can easily shift between sample types without needing tool-assisted reconfiguration. Its compact size fits standard lab stands without obstructing nearby instrumentation. The rotating shaft aligns accurately even when vessels are repositioned mid-process. This flexibility allows users to switch applications quickly without changing core components.
The Overhead Stirrer LOSR-E12 allows external temperature sensing via PT100 connectivity for in-sample thermal tracking. Our overhead stirrer permits researchers to insert the probe directly into the reacting medium to observe real-time changes. This functionality is critical in experiments where exothermic or endothermic responses must be recorded during agitation. The temperature data supports validation of mixing stability for pharmaceutical or biochemical formulations. Our overhead stirrer enables consistent heat-sensitive workflows by combining thermal feedback with stable shaft rotation. The positioning of the shaft does not interfere with the temperature sensor’s immersion depth. It enables stepwise temperature control when paired with auxiliary heating equipment. This integration improves accuracy in protocols involving solubility, crystallization, or emulsification.
The Overhead Stirrer LOSR-E12 features a chemically resistant outer surface that protects against splashes, spills, and reactive vapors. Our overhead stirrer is ideal for fume hoods or bench-top use where acidic or solvent-based mixtures are stirred regularly. The smooth casing allows easy wipe-down without the risk of damaging internal electronics. Its housing prevents liquid ingress into the motor zone, preserving long-term performance. Our overhead stirrer’s shaft components resist corrosion, even under exposure to aggressive compounds. It minimizes downtime in environments where frequent cleaning is necessary due to spillage or contamination. The sealed design also keeps airborne particulates from entering and damaging motor components. This makes it dependable in labs where both cleanliness and chemical resistance are critical.
