Development of the Prism high-speed micro centrifuges started with feedback from our thousands of Life Science customers worldwide. We summarized this feedback and put our design and development teams to work to create an easy-to-use, high performance centrifuge in a modern and attractive form. Our new friction fit lid latching system combines reliability and safety with easy operation. The updated control panel with a single large control knob and easy to read Liquid Crystal Display provides an intuitive interface for operation. Speed (in RPM or G-Force) and run time can be quickly and accurately set, and actual speed and time remaining are displayed during a run. A momentary spin function is activated by pressing and holding the quick key. The Prism uniquely designed 24-place rotor allows easy access to the tops of sample tubes, allowing for faster work flow. The individual tube slots in the solid rotor support tubes along their length to eliminate tube deformation or cracking even at the highest speed settings. In the event of a tube failure, tube pieces and samples are contained within the sample well. The rotor is designed to hold all standard 1. 5/2. 0ml tubes (both conical bottom and skirted), and the snap on lid offers space for micro-filter filters that fit into the tops of the tubes. Adapters are available for processing smaller tubes, and our exclusive Strip Spin" Adapter fits onto the top of the rotor for centrifuging standard 8-tube PCR strips. The rotor is seated on a tapered shaft which facilitates easy removal of the rotor for cleaning and autoclaving. The Prism Air-Cooled Micro centrifuge offers a maximum speed of 15, 000 rpm / 21, 200 x g for very efficient separation of nucleic acids and protein samples. Quick acceleration and deceleration reduce processing time, and our uniquemulti-flowair cooling system keeps the rotor and samples close to ambient temperature with minimal noise. The new Prism R Refrigerated Micro centrifuge is quickly becoming the benchmark in the refrigerated micro centrifuge category. In spite of its remarkably small footprint, the Prism R has a powerful cooling capacity and brushless motor to spare. The powerful refrigeration system maintains temperatures as low as -10°C and is designed to reach 4°C (from room temperature) in less than 8 minutes. The brushless motor drive quickly and effortlessly accelerates the rotor to set speed. A computer designed isolation system ensures vibration free operation, even with a slight imbalance. The Prism R is also equipped with an imbalance detection system that automatically shuts down operation in the event of a significant imbalance.
