Description: Beckman JA-20.1 Fixed Angle Centrifuge Aluminum Rotor 32 x 15 mL Place 20,000 RPM ( 51,500 x g ), Comes with Lid Condition: Used in Clean, Excellent working condition.Beckman Product #: 342095 for JA-20.1 rotor assemblyBeckman Product #: 341976 for Lid VWR Catalog #: BK342095 More Options:Beckman Product #: 358368 for Lid attachment bolt assemblyDescriptionThis JA-20.1 rotor has been manufactured in an NSAI-registered ISO 9001 or 13485 facility for use with the specified Beckman Coulter centrifuges.The JA-20.1, rated for 20 000 rpm, is a fixed angle rotor designed to centrifuge up to thirty-two 15-mL tubes in two concentric rows at a 23-degree angle. Used in Beckman Coulter J2 series, J6 series, and Avanti J series centrifuges, the rotor develops centrifugal forces that can efficiently pellet subcellular particles, bacteria, algae, and chloroplasts, or in short-column banding of viruses and subcellular particles. Up to 480 mL of gradient and sample can be centrifuged per run.A hold-down knob (354456) can be used to secure the rotor to the centrifuge without using the rotor lid.O-rings made of Buna N rubber in the lid and rotor body maintain atmospheric pressure inside the rotor during centrifugation, if they are properly lubricated. Two pins in the rotor drive hole mate with grooves in the centrifuge drive hub (in older model centrifuges), or with drive hub teeth (new model centrifuges), to prevent the rotor from slipping during acceleration and deceleration.Specifications Maximum Speed 20,000 rpm Critical Speed Range 600 to 800 rpm Density Rating at Maximum Speed 1.2 g/mL Maximum Allowable Imbalance of Opposing Loads 2 grams Relative Centrifugal Field (RCF) at Maximum Speed - Outer Row of Tubes at rmax (115 mm) 51,500 × g - Outer Row of Tubes at rmax with adapter 342327 (107 mm) 47,900 × g - Outer Row of Tubes at rmin (64 mm) 28,700 × g - Inner Row of Tubes at rmax (98 mm) 43,900 × g - Inner Row of Tubes at rmax with adapter 342327 (90 mm) 40,300 × g - Inner Row of Tubes at rmin (47 mm) 21,100 × g k Factors at Maximum Speed - Outer Row of Tubes 371 - Outer Row of Tubes with adapter 342327 325 - Inner Row of Tubes 465 - Inner Row of Tubes with adapter 342327 411 Number of Tube Cavities 32 Nominal Tube Dimensions (Largest Tube) 18 × 99 mm Nominal Tube Capacity (Largest Tube) 15 mL Nominal Rotor Capacity 480 mL Approximate Acceleration Time to Maximum Speed (Rotor Fully Loaded) 1 1/2 min Approximate Deceleration Time from Maximum Speed (Rotor Fully Loaded) 2 1/2 min Weight of Fully Loaded Rotor 7.5 kg (16.5 lb) Rotor Material Aluminum Rotor Entry Code for Avanti J-E, J2, and J6 Series Microprocessor-Controlled Centrifuges 20.1 Sku: BJBD.K33.562/
