Power Requirements and Shipping Considerations
The Beckman Coulter Allegra X-12R 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 X-12R contains refrigeration components, precision electronics, and a drive system, it typically requires careful packaging and may ship via palletized freight carrier depending on destination and configuration. Laboratories should verify delivery access, bench space, and placement requirements prior to shipment.
American Instrument Exchange can assist customers with freight coordination, shipping preparation, and installation planning.
