Overhead Stirrer LOSR-E13 Catalog
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.








Overhead Stirrer LOSR-E13 supports a wide range of mixing procedures such as emulsification, sample dispersion, and liquid blending across research-intensive environments. It accommodates tasks that demand stable torque delivery during varying material conditions. The design allows switching between gentle and intensive stirring without losing axis stability. Protective internal systems enable extended operations under continuous load. The user interface gives clear access to performance variables without disrupting workflow. Its structure makes it adaptable for alternating sample types and shifting protocols. It fits applications involving liquid-solid reactions or multi-phase processing. This stirring unit supports analytical testing and formulation stages with high material variability.
Overhead Stirrer LOSR-E13 features protective mechanisms that interrupt motion when the system detects overload stress during operation. It uses built-in response protocols to protect the internal motor and mechanical parts from damage. Its sealed housing prevents environmental factors from interfering with electronics or moving components. The unit avoids tip instability, keeping connected glassware or vessels steady. Safety mechanisms activate automatically without user intervention. The overall frame maintains its balance even under fluctuating resistance levels. Shocks or system halts do not affect the outer platform or workspace. This model is suited for environments with high viscosity samples or abrupt density shifts.
Overhead Stirrer LOSR-E13 is compatible with laboratory systems that require remote monitoring or controlled stirring operations. It is equipped with a communication interface that links to PC software platforms for command input and performance feedback. Users can view recorded changes in torque, stirring cycles, and temperature during the process. This reduces the need for manual tracking while improving accuracy across experiments. It enhances workflow automation and minimizes variability in repetitive trials. External devices can send instructions directly to the stirrer for coordinated sequences. Timing, speed, and reaction tracking become digitally accessible. This functionality is ideal for labs with automated chemical handling or data acquisition systems.
Overhead Stirrer LOSR-E13 is designed with a front-access shaft adjustment that allows easy rod replacement without lifting or shifting the motor head. This eliminates the need to reposition mounted components, saving time between batch processes. It’s suitable for workflows that require frequent tool swaps or multi-viscosity sample handling. Technicians can perform shaft changes while preserving vertical alignment and base contact. This layout avoids unwanted disturbance to nearby glassware or sensor systems. It ensures sample containers stay undisturbed while preparing for the next trial. The design prevents the loss of axis calibration during part transition. This feature supports quick turnaround in dynamic research environments.
Overhead Stirrer LOSR-E13 is engineered to maintain mechanical balance during continuous stirring, which helps isolate vibrations from the benchtop. Its torque delivery remains centered, reducing any lateral motion that could interfere with sensitive instruments. The motor and base are structured to absorb operational shifts and prevent resonance. This is useful in labs where small disruptions could affect scales or analytical sensors. Shaft movement retains axial alignment under extended rotation. The construction supports both low and high-speed stirring without amplifying workspace noise. The chuck holds the rod firmly to avoid loose motion. It is ideal for use alongside calibration or glassware-sensitive experiments.
Overhead Stirrer LOSR-E13 features a programmable system that allows researchers to schedule operation windows for unattended use. Timing controls enable repeat cycles, eliminating the need for round-the-clock observation. The integrated display keeps users informed of all running parameters during and after execution. This setup works well in endurance testing or sample incubation studies. Built-in safety cutoffs activate once thresholds are exceeded, preventing sample loss. Its consistent speed control reduces drift over extended hours. Users can set, leave, and return without major calibration requirements. This functionality is suited for labs conducting long-running formulation or reaction studies.
