STP-L451 - Low Vibration Vacuum STP Pumps

The new Edwards STP-L451(C) has been designed to meet the low vibration requirements of advanced spectroscopy and microscopy tools.

Features and benefits

  • Low vibration
  • Built in vibration isolation system gives improved performance over STP451(C) and external isolator
  • Increased pumping performance
  • No external isolator so conductance losses are reduced giving true 450 l/s performance
  • More compact design
  • Considerably smaller than STP451(C) and external isolator
  • Easy installation
  • One single pump component reduces installation time
