REMI R-248 M Centrifuge Rotor – 24 × 1.5 mL Fixed-Angle Rotor

The REMI R-248 M Centrifuge Rotor is a laboratory centrifuge accessory designed to accommodate 24 microcentrifuge tubes with a capacity of 1.5 mL each. It is intended for sample separation and preparation procedures in molecular biology, biochemistry, biotechnology, pharmaceutical research, and other laboratory applications. The REMI product catalogue lists the R-248 M as an angular rotor with a plastic tube configuration for 24 × 1.5 mL samples.

Centrifuge rotors are essential components of laboratory centrifugation systems. They hold sample tubes in a defined arrangement and transfer rotational force from the centrifuge drive to the samples. During operation, centrifugal force facilitates the separation of sample components according to their sedimentation properties, density, and particle size.

The R-248 M rotor is designed for laboratories that routinely process multiple small-volume samples. Its 24-position arrangement enables researchers and laboratory technicians to process several specimens in one run, helping organize sample preparation and improve laboratory workflow efficiency. The 1.5 mL tube format is commonly used for biological samples, cell suspensions, protein preparations, nucleic acid extracts, and reagent mixtures.

The rotor's angular configuration positions the tubes at a fixed angle during rotation. Fixed-angle rotors are commonly used for applications requiring sedimentation of particles and collection of pellets from liquid samples. Depending on the centrifugation protocol, these procedures may support the preparation of cell fractions, precipitation products, and other laboratory materials.

The R-248 M is listed for use with compatible REMI R-24 and PR-24 centrifuge systems. Published catalogue specifications indicate different maximum operating speeds for these centrifuge configurations. The listed maximum speed is 17,300 rpm for the R-24 and 20,000 rpm for the PR-24, with corresponding relative centrifugal forces of approximately 27,440 × g and 37,570 × g, respectively. These values must be verified against the specific centrifuge, rotor condition, and applicable manufacturer documentation before operation.

The rotor is suitable for laboratories conducting routine sample preparation in research, educational, and industrial environments. Potential applications include nucleic acid extraction workflows, protein sample preparation, sedimentation of cellular material, and separation of suspended particles. The actual suitability of the rotor depends on the sample type, tube specifications, centrifugation settings, and the requirements of the laboratory procedure.

Before use, the rotor should be inspected for cracks, deformation, corrosion where applicable, damaged tube positions, and other signs of deterioration. Sample tubes must be compatible with the rotor, and opposing positions must be balanced according to the centrifuge manufacturer's instructions. A rotor should never be operated above its approved speed limit or installed in a centrifuge model for which compatibility has not been confirmed.

The REMI R-248 M Centrifuge Rotor is a practical accessory for laboratories that require a multi-position rotor for small-volume sample processing. Its 24-tube configuration supports organized sample handling and efficient centrifugation workflows. When correctly matched to a compatible centrifuge and operated within approved limits, it can support routine laboratory separation procedures.

The pictured product is identified as R-248 M with a capacity of 24 × 1.5 mL. Buyers should confirm whether the rotor is supplied with any additional components, such as a lid or accessories, and verify its condition before purchasing.
