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.








Our Overhead Stirrer LOSR-E15 includes an integrated thermal monitoring system that shuts down the motor under excessive heat buildup, preventing long-term wear. This allows it to operate for extended durations without compromising performance. The stable support frame design resists vibrations, even at higher viscosities. Its shaft locking design keeps the rod firmly in place during operation. Cable routing is organized to prevent accidental disconnection or entanglement. This approach helps protect the instrument during prolonged tasks. The housing structure prevents ingress of chemicals, shielding its electronics. Our unit is crafted for demanding mixing routines across production labs.
The Overhead Stirrer LOSR-E15 offers reverse stirring direction, which helps blend components that settle differently or react sequentially. This function ensures uniformity when mixing suspensions or solutions that demand alternating agitation. Its real-time speed display keeps users updated on every shift in velocity. Built-in safeguards prevent sudden power surges from impacting performance. This design is especially effective for laboratories managing complex reagent combinations. The support clamp adjusts vertically to accommodate vessels of varying heights. With quiet operation, the stirrer supports uninterrupted benchwork. The unit adapts well to fluctuating load resistance found in multi-reagent setups.
Labtron’s Overhead Stirrer LOSR-E15 includes external temperature sensing support that enables users to monitor sample temperatures while stirring, especially helpful for thermally reactive mixtures. This feature maintains integrity during heating or cooling stages. The stirrer head remains fixed even when temperature probes are inserted, ensuring consistent positioning. It minimizes heat loss or gain through exposed surfaces, improving stability. The materials used resist degradation from common solvents used in thermal studies. This allows extended use in heated environments without affecting the performance. Our instrument adapts well to both organic and aqueous temperature-sensitive compounds.
The Overhead Stirrer LOSR-E15 features programmable run durations, allowing users to assign fixed mixing cycles without needing constant supervision. This automation ensures batch-to-batch consistency, especially in research setups. Its secure chuck system holds the shaft firmly, reducing drift over extended usage. The device resumes set programs even after brief interruptions in power, supporting workflow continuity. Its consistent torque delivery ensures the same quality of mixing across multiple trials. This is ideal for analytical methods that demand identical stirring intervals. The structure is built to handle recurring high viscosity loads across multiple tests.
Our Overhead Stirrer LOSR-E15 features a height-adjustable clamping mechanism that accommodates various beaker and flask sizes without repositioning the base unit. This vertical adjustment is helpful when shifting between narrow and tall vessels. Its compact motor housing ensures that space above the workspace remains unobstructed. The flat base enhances placement stability, even on narrow shelves or confined hoods. The stirrer body includes cable management slots to avoid workspace clutter. This makes the system ideal for dense bench-top setups. Our stirrer aligns easily with other instruments within shared setups without interference.
The Overhead Stirrer LOSR-E15 includes RS232 connectivity, enabling integration with lab data logging systems or programmable control units. This connectivity allows stirring operations to be linked with broader lab automation workflows. Parameters such as runtime and speed can be tracked or adjusted remotely. This compatibility supports research environments where digital traceability is critical. By enabling batch reporting or audit trails, the device fits well into compliance-focused settings. Our system supports flexible coordination with other lab technologies. The port positioning allows quick access without interfering with operational controls.
