Benchmark Scientific's MC-12-E High Speed Microcentrifuge is a compact microcentrifuge capable of achieving centrifugal speeds up to the critical threshold of 16,000 xg, often held as the standard for many molecular biology/DNA protocols. It's brushless, maintenance free drive system makes it powerful, yet compact enough to allow each work station to be fully equipped with a personal centrifuge. The MC12-E defines a new class of microcentrifuge: compact, quick, powerful and affordable. All aspects of microcentrifuge performance were taken into consideration and no compromises were made. In addition to its unsurpassed speed, the MC 12 E also delivers shortened acceleration/deceleration times, whisper quiet operation and its computer-designed airflow pattern minimizes sample temperature increases during longer runs at high speeds. All operating parameters are set using a single, conveniently located control knob and the large, bright LCD provides a clear indication of time and rpm or g-force. A separate momentary spin button permits instant spin downs, without setting or disturbing any preset parameters. The aircraft grade aluminium rotor accepts 1.5 to 2.0 ml tubes directly, as well as 0.5 and 0.2 ml tubes with optional adapters. For applications requiring sub-ambient temperatures, the MC-12-E is cold room safe. This model uses a 230 V EU plug for its power source.
