The Q-sep centrifuge is a continuous-duty, electronically controlled, horizontal laboratory centrifuge with a lid safety interlock system. The unit is controlled by an electronic push-button timer that is variable from one to 30 minutes for precise spin times and ease of use. Samples can be safely viewed through the transparent lid. The imbalance detection system safely terminates a run cycle in the event that a load is severely imbalanced. Entry into the machine is restricted during operation by the safety interlock system. The Q-sep centrifuge features a lighted control panel that displays the status of the machine, easily viewable from a distance. The unit comes with presets for AOAC and EN methods or up to 10 custom cycles can be programmed with full control of time, braking, and speed or g-force (up to 4500 rpm or 3450 xg).

Intended Use

General-purpose laboratory centrifuge intended for safe and rapid density-based separation of fluids, including physiologic fluids, in approved specimen receptacles for qualitative or quantitative test procedures. As a general-purpose laboratory centrifuge, it is designed to also run other approved containers filled with chemicals (nonflammable, nonexplosive, nonvolatile, and non-highly reactive only), environmental samples, and other nonhuman body samples. This device is intended to be operated by properly trained personnel who have carefully read the operating manual and are familiar with the function of the device.
