Beckman Allegra X-12R Centrifuge with SX4750A Rotor and Buckets – Introduction

The Beckman Allegra X-12R Refrigerated Centrifuge with SX4750A Rotor and Buckets is a high-performance benchtop centrifuge system developed by Beckman Coulter Life Sciences for reliable sample separation in biomedical, pharmaceutical, biotechnology, clinical research, and academic laboratories. Designed for versatile laboratory workflows, the Allegra X-12R combines powerful centrifugal performance, precise temperature control, large-capacity sample processing, and user-friendly operation.

Equipped with the SX4750A ARIES™ Swinging-Bucket Rotor, the Allegra X-12R provides excellent flexibility for processing a wide range of sample types, including cell culture samples, proteins, nucleic acids, biological particles, and chemical preparations. The SX4750A rotor uses a swinging-bucket design that allows tubes and bottles to remain vertical during loading and gradually swing to a horizontal position during centrifugation, producing efficient sedimentation and improved pellet formation. The rotor supports four 750 mL buckets, providing a total capacity of up to 3 liters per run. 

The Allegra X-12R refrigerated centrifuge features a robust drive system and advanced temperature management technology to maintain sample integrity during extended centrifugation procedures. Refrigerated operation is particularly important for biological samples that require controlled temperatures to prevent degradation or loss of activity.

The SX4750A rotor is designed for high-volume applications such as rapid sedimentation of cells, cell debris, protein precipitates, and large biological particles. The rotor incorporates Smart Balance technology, which helps compensate for minor load imbalances and improves operational safety. The rotor can also accommodate various adapters, including cell culture flask adapters, bottle sleeves, blood bag cups, and microplate carriers, increasing laboratory flexibility. 

The Allegra X-12R provides programmable centrifugation control, allowing users to set acceleration, deceleration, speed, time, and temperature parameters according to specific protocols. Its intuitive interface simplifies operation and improves reproducibility between runs.

The system is widely applied in cell biology, molecular biology, biotechnology production, pharmaceutical research, and clinical laboratory workflows. Its large-capacity swinging-bucket configuration makes it suitable for laboratories requiring efficient processing of multiple samples or larger volumes.

Due to its durable construction, reliable performance, and flexible rotor compatibility, the Beckman Allegra X-12R Centrifuge with SX4750A Rotor and Buckets remains highly valued in both research laboratories and the refurbished laboratory equipment market. It provides an economical and dependable solution for laboratories seeking professional refrigerated centrifugation capability.
