HandyStep® S

  • for serial pipetting of volumes between 2 µl and 5 ml. A close-tolerance stepping mechanism allows the HandyStep® S repetitive pipette to offer precise repetition of the selected volume. With up to 49 dispensing steps from each aspiration, it is ideal for making aliquots of stock liquids.
  • the instrument works on the positive displacement principle, making it suitable for routine dispensing, as well as for difficult liquids. Viscous, high density or high vapor pressure liquids can be dispensed while maintaining accuracy and precision.
  • conformity certified, with performance certificate
  • ergonomic
  • one-hand operation
  • separate tip ejector
  • superior handling
  • maintenance-free
  • factory adjusted
  • approved for in-vitro diagnostic (IVD) applications according to IVD directive 98/79/EC, with CE-mark
