Used Lab Equipment

Features:

The Optima MAX and MAX-E (see Figure 1-1) microprocessor controlled tabletop ultracentrifuges generate high centrifugal forces for a variety of high-speed applications. The instrument design features a variable-frequency induction drive, the thermoelectric temperature control system, self-purging vacuum system, rotor overspeed identification system, program memory that can contain up to ten five-step programs, and a choice of acceleration and deceleration rates.

Manual and programmed operation are available. • In manual operation, you enter the individual run parameters before beginning each run. • In programmed operation, you can duplicate runs quickly and accurately by selecting one of ten programs previously entered into the program memory. Each program can contain up to five steps. User messages and/or audible signals are provided to alert you to conditions that may need attention. An optional feature of the Optima MAX or MAX-E is the RS 232C Interface Accessory, which enables it to be connected to a personal computer. Information about this feature will be supplied upon request.
