Power Requirements and Shipping Considerations
The Beckman Coulter Allegra 6R typically requires 120V, 50/60Hz electrical service and is designed for benchtop laboratory installation. Laboratories should verify electrical compatibility, available bench space, ventilation requirements, and installation location prior to purchasing this centrifuge.
Because the Allegra 6R contains refrigeration components, precision electronics, and a laboratory-grade drive system, it typically ships via palletized freight carrier. Laboratories should verify delivery access, bench space, and final placement requirements prior to shipment.
American Instrument Exchange can assist customers with freight coordination, shipping preparation, and installation planning.
