Model: Optima MAX-130K Ultracentrifuge
The Optima MAX microprocessor controlled tabletop ultracentrifuge generates high centrifugal forces for a variety of high-speed applications.
The aluminum rotor chamber is coated with a chemical-resistant epoxy finish to resist corrosion. The rotor drive hub and speed sensors are visible in the bottom of the chamber.
A diffusion pump, in series with a mechanical vacuum pump, reduces chamber pressure to below 10 microns (1.34 Pa). The vacuum pump starts automatically when the power is turned on and the door is closed. The diffusion pump is automatically activated when chamber pressure reaches about 500 microns. When the instrument is on and the door closed, a self-purging system continuously removes moisture from the vacuum system.
The solid-state thermoelectric temperature control system uses only forced air?no coolant is required. With the power on, the temperature control system is activated when the door is closed and the vacuum system comes on. Run temperature can be set between 0 and 40°C. If no set temperature is entered, the instrument automatically selects the last entered temperature. (For the first run of a new instrument, 25°C is the default operating temperature.) A sensor in the rotor chamber continuously monitors chamber temperature. The microprocessor calculates the required chamber temperature to maintain the selected rotor temperature. Peak-to-peak fluctuations of rotor temperature (after reaching thermoequilibrium) will be within 0.1°C.
The air-cooled direct-drive induction motor is frequency controlled, with no gears or brushes. In addition, the drive does not require an oil vacuum seal or external oil reservoir. Externally cooled by forced air and internally cooled by oil, the drive delivers ultra-smooth, quiet performance.
The control panel with digital displays, run-parameter keys, keypad, power switch is used to enter run parameters via touch keys and a keypad, and to display run parameters and program information. A beep sounds when a key has been pressed and the input accepted.
User messages appear on the control panel to assist you in properly operating the instrument or to alert you to conditions requiring attention.
The steel chamber door has an electromechanical door-locking mechanism to prevent operator contact with a spinning rotor. When the door is closed it locks automatically. It can be unlocked only by pressing "door", and opened only when the power is on and the rotor is at rest.
