Fast, Efficient Separations

  • Spindle Drive technology delivers rapid acceleration and quick braking to speed throughput and extend instrument life
  • Quiet operation
  • High g-forces for faster separations over a wider range of applications
  • Dual lid-locking for improved safety

Continuous Imbalance Tolerance Protects Samples

  • Indentifies improper rotor installation to protect drive
  • Detects excessive speed and signals maximum permissible value for rotor
  • Allows eye balancing of tubes to speed sample preparation

Smart, Intuitive Controls

  • Easy-control panel is intuitive and simple to navigate
  • Stores 9 programs for most-used run parameters
  • Pre-temp program for rapid cooling
