The USA E8 centrifuge is designed, engineered, and assembled at LW Scientific’s ISO-certified, registered manufacturing facility in Lawrenceville, GA. Expect American quality as well as customary LW Scientific support. This new model is loaded with features and improvements, such as higher speeds for faster and cleaner separations, quieter operation for peaceful work environments, lower chamber temperatures for cooler test-tube samples, shorter height to fit under any cabinet, and auto-calibrating speed function for precision results. It even has an auto-brake to stop the rotor in less than 30 seconds to save time in the busy labs. Choose the lowest-priced Fixed Speed model for spinning blood only.
