The Optima XE generates centrifugal forces for the separation of particles. Classified S, it can be used with all currently manufactured Beckman Coulter preparative rotors. It is intended for the separation of components through the use of relative centrifugal force. The Optima XE is designed to separate human samples, including blood and other body fluids, for processing, analysis, and in vitro diagnostic testing, as well as nonhuman body samples and chemicals, including industrial and environmental samples.
The touch screen on the Optima XE is both the information display and the control input for the instrument. As they are needed, control buttons appear on the screen. When you select a button, you activate that control. The touch screen position is adjustable (both swivel and tilt) to be made viewable from nearly anywhere in the lab. This is especially useful in environments where a single operator may oversee a number of instruments.
The rotor chamber is made of aluminum and coated with a chemical-resistant epoxy finish. The central feature is the rotor drive spindle, but several sensors and control systems are also contained in the rotor chamber.
The Optima XE uses a diffusion pump in series with a mechanical vacuum pump to reduce chamber pressure to a very low level. The system starts automatically when you start a run, or manually when the chamber door is closed, and you use the Vacuum Display/Button on the Footer Bar of the Home Page. When the vacuum system is on, the chamber pressure is displayed in microns in the Vacuum Display/Button.
At the end of a run, press the Vacuum Display/Button to vent the chamber vacuum before attempting to open the door. When the chamber vacuum is reduced to the point that you can open the door, the system sounds an audible tone. After you open the door, there is a five-minute period where the chamber temperature remains as set (to allow back-to-back runs). Then the chamber returns to approximate room temperature to minimize condensation collecting in the chamber. To help keep the chamber dry and clean, keep the door closed whenever possible. If you wish to vent the chamber before the rotor has come to a complete stop, you can do so as soon as it slows below 3000 rpm.
In zonal or continuous flow operation, the door may remain open while the rotor is spinning up to the loading speed. The vacuum system is activated when the door is closed, and the rotor speed is above 3000 rpm (after loading the rotor). Normally, you vent the chamber at the end of the run when the rotor has decelerated to the unloading speed, but you can vent the chamber when the rotor has decelerated below 3000 rpm if the unloading speed is slower than that
The high-strength structural steel chamber door has a solenoid interlock to prevent operator contact with a spinning rotor. When the door is closed and a run begins, it locks automatically. It can be opened only when the power is on and the rotor is at rest with the chamber at atmospheric pressure. If there is a power failure, you can manually unlock the door
A 41-mm (1.63-in.) steel alloy armor ring acts as the primary barrier, surrounded by a 13-mm (0.5-in.) vacuum chamber to provide full protection for the operator.
An imbalance detector monitors the rotor during the run, causing automatic shutdown if rotor loads are severely out of balance. Even at low speeds, an incorrectly loaded rotor can cause an imbalance.
The overspeed system is a safety feature designed to ensure that the rotor does not exceed its maximum allowable speed. This system includes a photoelectric device in the rotor chamber next to the drive spindle and an overspeed disk on the bottom of the rotor. Individual rotor manuals provide information on the correct overspeed disks to be used with each rotor.
The overspeed disk has alternating light and dark sectors. As the rotor spins, the passage of reflecting and non-reflecting sectors over the photoelectric device generates a series of pulses detected by the electronic circuitry and software.
After the rotor reaches 600 rpm, the set speed is checked against the overspeed disk. If the set speed is greater than the maximum speed permitted by the disk, the speed setting is automatically lowered to the maximum speed of the disk, but the run continues without interruption. An error message appears to alert you to the change.
As the rotor accelerates between 15000 and 20000 rpm, the instrument checks the rotor inertia and calculates the rotor energy for the speed set by the user. If the calculated rotor energy is excessive, the instrument stops the run with braking to avoid possible damage and sends a diagnostic message to alert you to this condition.
The Optima XE instrument will make an audible sound while displaying a corresponding visual prompt with the following events: Boot up, start of run, end of run, diagnostics/alert, vacuum low enough to open door, door open during zonal or continuous flow mode.
All of our equipment is used and reconditioned. Our technicians test the performance of all centrifuges and make sure the rotating assembly is properly balanced; the bearings, seals and gaskets on the spindle assembly are in good shape; and the controls work properly. If the centrifuge is refrigerated, we also test to make sure that the machine reaches and hold temperature properly. All tolerances are measured and the exterior and interior of all units are fully cleaned. If the unit is being purchased with a rotor, we test the rotor/centrifuge combination together.
The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
