This rotor is not only lightweight but also versatile, ideal for a variety of applications including pelleting and density gradient separations. It is perfectly suited for the separation of proteins, lysate and tissue homogenates, nucleic acids, cells, viruses, and blood components. Designed to be used with the Avanti J Series centrifuges, it enhances the efficiency and productivity of your laboratory processes.

Our JA-14.50 rotor assembly (DATE OF MFG. 04/21), biosafe (with dual-locking lid) is available at a bargain price with our Beckman Coulter Avanti JXN-30 Centrifuge. This package deal is a great value for researchers and biotech startups.

Salient Features of the JA-14.50 Fixed-Angle Rotor

The JA-14.50 Fixed-Angle Rotor is designed for use with Beckman Coulter Avanti J Series centrifuges. It is suitable for a wide range of applications, including pelleting cells, bacteria, and food products, as well as separating proteins, viruses, and subcellular fractions.

Key Specifications:

• Maximum Speed: 14,000 RPM

• Maximum Relative Centrifugal Force (RCF): 35,000 × g at maximum radius

• Rotor Capacity: 16 tubes, each with a capacity of 50 mL

• Rotor Angle: 35 degrees

• Material: Anodized aluminum rotor body with Buna-N and ethylene propylene rubber O-rings

• Nominal Rotor Capacity: 800 mL

Design and Features:

• Dual-Locking and Single-Locking Lid Options: The rotor is available with either a dual-locking or single-locking lid for secure operation. The dual-locking lid allows for safe tube handling under a safety hood.

• Fluid-Containment Annulus: The patented design helps retain liquid that may escape from overfilled or leaking tubes, minimizing the risk of contamination.

• Versatile Applications: Ideal for pelleting, phase separation, and binding studies. The rotor can also be used for high-speed centrifugation of biological samples.

Maintenance and Care:

• Lubrication: Regularly apply Spinkote lubricant to metal threads and silicone vacuum grease to O-rings to maintain sealing integrity.

• Cleaning: Wash the rotor with a mild detergent such as Solution 555, rinse with distilled water, and air-dry. Avoid using acetone or harsh chemicals.

• Decontamination: Use RadCon Surface Spray, IsoClean Solution, or Radiacwash for decontamination, following proper safety protocols.
