The MyFuge™ 5 micro centrifuge includes a four position rotor for compatibility with a variety of 5mL test tubes, including 5mL snap cap centrifuge tubes. In addition, this combination rotor has four additional slots for centrifuging standard micro tubes (1.5/2.0ml). Simply close the lid and the centrifuge quickly accelerates to the fixed speed of 5,500rpm. Open the lid, and the rotor decelerates to a stop for removing samples.The 5mL rotor positions accepts 5mL centrifuge tubes (snap cap) directly. While 5mL blood and culture tubes (12x75mm) and cryovials are also accepted with the included adapters. The micro tube positions are also designed to accept 0.5 and 0.2mL tubes with the use of optional adapters, and a PCR rotor is also available for use with eight position PCR strips.
