The MyFuge™ 5 microcentrifuge includes a four position rotor for compatibility with a variety of 5mL test tubes, including 5mL conical centrifuge tubes. In addition, this combination rotor has four additional slots for centrifuging standard microtubes (1.5/2.0mL). Simply close the lid and the centrifuge quickly accelerates to the fixed speed of 5500rpm. Open the lid, and the rotor decelerates to a stop for removing samples. The 5mL rotor positions accepts 5mL centrifuge tubes directly. 5mL blood & culture tubes (12x75mm) and cryovials are also accepted with the included adapters. The microtube positions are also designed to accept 0.5 and 0.2mL tubes with the use of optional adapters.
