Low Speed Centrifuge LLS-E13

The Low Speed Centrifuge LLS-E13 from Labtron is primarily used for separating the components of a mixture based on their densities. By spinning liquid samples at relatively low revolutions per minute (RPM), it facilitates the sedimentation of heavier particles to the bottom of the centrifuge tube. This makes it especially effective for applications like the separation of blood components (e.g., plasma from cells), sedimentation of urine for microscopic analysis, or initial clarification of biological samples. Its low speed operation ensures that fragile components such as red blood cells or epithelial cells remain intact, which is essential in clinical and diagnostic procedures. The LLS-E13 is a staple in clinical labs, academic teaching settings, and small research labs due to its reliable, reproducible, and gentle centrifugation.

The Labtron LLS-E13 is designed to operate at a maximum speed typically between 4000 and 5000 RPM, depending on the specific model and rotor type used. This range allows for gentle separation processes that prevent cellular damage. The centrifuge supports various rotor configurations, usually accommodating 6 to 12 centrifuge tubes per run, with capacities ranging from 5 mL to 15 mL. This makes it versatile for batch processing of small to medium sample volumes. The rotor’s design also ensures uniform sample separation by maintaining balance and symmetry during operation. Users can choose from fixed-angle or swing-out rotor options based on their application requirements.

Labtron’s LLS-E13 includes an automatic lid locking system that prevents the lid from opening while the rotor is in motion, minimizing the risk of sample spillage or injury. Imbalance detection is another critical feature, which stops the machine if the rotor is unevenly loaded, thereby preventing mechanical stress or failure. Additionally, over-speed protection ensures the rotor never exceeds the safe operational limits, and motor overheating protection extends the life of the motor while protecting samples. The base typically includes anti-vibration feet or suction cups to secure the unit during operation, reducing noise and ensuring operator safety.

Yes, the Labtron LLS-E13 offers precise control over both speed and run time through either a digital or analog control interface. Users can set the RPM (revolutions per minute) or RCF (relative centrifugal force) depending on their experimental needs. Run times can usually be programmed between 1 minute to 99 minutes, with some models offering a continuous run feature for extended separations. This programmability ensures accurate and repeatable results, which is crucial for diagnostic labs and research environments. It also allows for the optimization of centrifugation protocols based on the type and sensitivity of the samples being processed.
