The Benchmark Scientific Z207ME Hermle High-Speed Microcentrifuge with EZ-Scroll Touch Pad (No Rotor), 230V is the perfect microcentrifuge for laboratories with valuable limited space who require quiet, and powerful centrifugation. The Z207-M-E's compact design houses a powerful, maintenance free, induction motor that can reach up to 17,317 xg. Accompanied by Hermle's easy to use control panel , the unique EZ-Scroll™ touch pad, gives you ease of control and a modern feel. An advanced microprocessor controls allow for setting/displaying of the rotational speed in either rpm or rcf in increments of 10. In addition to retrieving saved programs, the easy to use front panel can be used to adjust accel/decel rates, run time, and change the end of run alarm tone. There is also a momentary spin function that will run while the button is pressed. Additionally the Z207-M-E features a sleep mode to save energy by shutting off after a certain time if not being used while on, which can be toggled on or off easily. All common microtubes 0.2ml, 0.5ml, 1.5ml, 2.0ml can be utilized in the standard 24-place rotor, as well as in a hermetically sealed, 24 place rotor for labs requiring an aerosol tight enclosure when working with hazardous chemical, or biological, samples. An optional 18 place spin column rotor is also available. With our Z207-M-E microcentrifuge, even the smallest laboratories can have high output with a small footprint.
