PR1MA™ MC-24 Touch High-Speed Microcentrifuge
The PR1MA™ MC-24 Touch is the first microcentrifuge in its class to feature touchscreen control. In addition to the next-generation control panel, the centrifuge also offers high speed (up to 13,500 rpm / 16,800 xg) and a unique COMBI-Rotor™ with lid that accepts both standard microtubes (1.5 / 2.0 mL) and PCR tubes/strips (0.2 mL), making this the perfect partner for any molecular biology laboratory.
The large, color touchscreen, shows the actual speed (in rpm or rcf) along with set and remaining time. Up to 9 speed/time profiles can be stored in memory and the home screen displays a “mySpin” icon for instant recalls a designated favorite profile.Supplied with Benchmark’s unique COMBI-Rotor™, the MC-24 Touch will accept 24 × 1.5 / 2.0 mL tubes, 2 strips of 0.2 mL tubes (16 × 0.2 mL), and up to 12x spin column kits without requiring separate adapters. There is also an optional 8-place rotor for 5 mL and cryo tubes. Samples are kept cool, even during extended runs at the maximum speed setting by a proprietary air flow system that moves air evenly and quietly throughout the chamber.
The MC-24 Touch is cold room safe and carries a 2-year warranty.
- Full-Color Touch Screen
- mySpin™ 1 button program recall
