Thermo Scientific MegaStar 4R Refrigerated Benchtop Centrifuge, 4,000 rpm, 3739 x g

The Thermo Scientific MegaStar 4R is a refrigerated benchtop centrifuge engineered to support routine and mid-throughput laboratory workflows, particularly in biotechnology, pharmaceutical research, and molecular diagnostics. Featuring a brushless induction motor coupled with microprocessor-based control, it delivers smooth acceleration, precise speed regulation, and quiet operation with noise levels below 63 dB.

Key technical specifications include a maximum speed of 4,000 rpm and relative centrifugal force (RCF) up to 3739 x g, with speed increments of 50 rpm for fine-tuned centrifugal performance. The temperature control system operates within a range of -10°C to +40°C, ensuring sample integrity during sensitive bioprocessing and gene editing applications. Acceleration and braking ramps are rated at 9 and 10, respectively, allowing secure and reproducible spin profiles.

Designed with laboratory ergonomics in mind, the compact unit measures 30 x 26 x 14 inches and weighs 258 lbs, enabling integration into space-constrained workbenches. The centrifuge supports up to 6 programmable spin programs and features an LCD display with timer settings for up to 9 hours 59 minutes or continuous operation. Safety and operational efficiency are enhanced through quick-change rotor locking and consistent refrigeration performance.

Widely adopted in synthetic biology research and molecular cloning workflows, the Thermo Scientific MegaStar 4R delivers reliable refrigerated centrifugation critical for biopharmaceutical production pipelines, cell imaging sample preparation, and clinical diagnostics. It includes the Thermo M20 microplate rotor and is backed by tested functionality and a 30-day warranty, making it a dependable choice for researchers demanding repeatable results in diverse biotech research fields.
