Thermo Scientific SL4R Plus Refrigerated Benchtop Centrifuge

The Thermo Scientific SL4R Plus is a high-performance, refrigerated benchtop centrifuge designed for the efficient separation and processing of biological samples, cell cultures, and other laboratory materials.

The centrifuge combines high processing capacity with precise temperature control and reliable centrifugation performance. Its refrigeration system allows temperature-sensitive samples to be processed under controlled conditions.

The SL4R Plus features microprocessor control and a powerful, low-maintenance brushless induction motor. The system offers various acceleration and deceleration profiles, enabling centrifugation processes to be precisely tailored to specific applications.

The centrifuge comes with two trays:

Tray 1: capacity for 2 × 24 tubes of 15 ml (48 tubes in total).

Tray 2: capacity for 4 × 10 tubes of 50 ml (40 tubes in total).

This makes the device suitable for a wide range of applications in clinical laboratories, biotechnology, microbiology, and the life sciences.

The combination of refrigeration technology, high capacity, and flexible rotor configurations makes the Thermo Scientific SL4R Plus a versatile solution for professional laboratory environments.
