Small Footprint, Big Impact

The PSD/4 is Hamilton's most compact syringe pump. The space saving design uses 30 mm half-height syringes and performs all standard liquid handling functions, including dispensing, serial dispensing and diluting.

  • 30 mm stroke length
  • Variety of mounting options — front, back, top, bottom, and side
  • Easy serviceability: Modular design allows quick plug and play replacement
  • Small footprint suits limited spaces
  • RoHS and CE compliant
