RotaValve™ for Agilent ICP-OES

An Enhanced, Switching Valve for AVS System

The RotaValve™ is a high-precision, durable switching valve that integrates seamlessly with Agilent 5000 Series ICP-OES systems, maintaining full compatibility with the mechanical, electrical, and fluidic interfaces of the AVS system—while offering enhanced durability and reliability.

Utilizing Flow Injection technology, the RotaValve reduces analysis time, environmental impact, and operating costs. Ideal for labs looking to extend system life and cut maintenance without sacrificing performance. Fully compatible with Agilent 5000 Series ICP-OES.




RotaValve with Nebulizer Connection on Agilent ICP-OES.

Key Features of the RotaValve:

  • Optimized for ICP: Purpose-built with low dead volume for precise sample injection and minimal carryover.
  • Purpose-Built for ICP: Low dead volume minimizes carryover and ensures accurate sample injection.
  • Compact, Efficient Design: Integrated mixing chamber ensures complete blending of sample and reagent for reliable results.
  • Dual Configuration Flexibility: Easily switch between 6-port and 7-port setups using a removable Tee, no valve change required.
  • Rugged & Field-Serviceable: Durable rotor/stator design resists chemicals and wear; only replace worn parts, not the entire valve.
  • Reliable, Leak-Free Sealing: ¼-28 ratchet fittings provide consistent torque and easy, tool-free sealing, no overtightening guesswork.
  • Seamless Compatibility: Plug-and-play with Agilent 5000 Series ICP-OES; no software modifications needed.

Valve Tubing Kit for Agilent® 5000 Series ICP-OES

  • The 6/7 Port Valve has been designed specifically for use in ICP analysis requiring the addition of an Internal Standard or Dilution of the sample. A major advantage is the incorporation of the Tee piece into the Valve design which reduces the number of components required.
  • The Valve is made up of one 6 Port Valve and is switched between two positions with a removable Tee piece creating the 7th Port for the Valve.
  • All ports on the 6/7 Port Valve have been numbered to allow easy connection to the Valve tubing kit.
  • Various Sample Loop sizes available on request
  • Requires Valve Tubing Kit P/N 70-803-1869
