Thermo Scientific Sorvall SLA-1500 Centrifuge Rotor – 6 × 250 mL Fixed-Angle Rotor

The Thermo Scientific Sorvall SLA-1500 Centrifuge Rotor is a high-capacity laboratory rotor designed for centrifugation and separation of samples in research, biotechnology, pharmaceutical, and industrial laboratory environments. It is designed to accommodate six 250 mL sample containers, making it suitable for workflows that require processing larger volumes in a single centrifugation run.

The SLA-1500 uses a fixed-angle configuration, in which sample containers remain positioned at a defined angle during rotation. This arrangement supports sedimentation and separation of suspended particles, cellular material, and precipitates. It is useful in laboratories where sample processing capacity and repeatable centrifugation procedures are important.

According to the manufacturer's published specifications, the SLA-1500 is constructed from aluminum and has a maximum rated speed of 15,000 rpm. Its maximum relative centrifugal force is approximately 34,155 × g at the specified rotor radius. The manufacturer also lists a maximum sample density of 1.2 g/mL. These limits must be followed alongside the operating requirements of the compatible centrifuge and sample containers.

The rotor is intended for use with specified Sorvall centrifuge platforms, including compatible RC-series and Evolution systems. Maximum permitted speed can vary with the centrifuge model. Before operation, users should consult the official rotor documentation to establish the correct speed limit for their specific centrifuge.

The SLA-1500 can support applications such as cell harvesting, biological sample sedimentation, biochemical sample preparation, and other laboratory separation procedures, provided the samples and containers are compatible with the rotor. The rotor should be used only with approved tubes or bottles, appropriate adapters where required, and a suitable balancing arrangement.

Routine inspection is essential for safe centrifuge operation. The rotor body, lid assembly, mounting interface, and sample positions should be checked for damage, corrosion, deformation, or other signs of deterioration. The rotor must be correctly installed, and samples must be balanced according to the manufacturer's instructions.

For laboratories processing medium-to-large sample volumes, the Sorvall SLA-1500 offers a six-position configuration that can reduce the number of centrifugation runs required. It is a specialized accessory for laboratories that need a compatible high-speed rotor rather than a complete centrifuge system.

The pictured product appears consistent with the Sorvall SLA-1500, but the label should be checked to confirm the model. The exact condition, serial number, included lid and accessories, and service history should be verified before purchase.
