Description

The Series 18 is designed for compact installation in multi-liquid systems. Available with multiple inlets and one outlet (or vice-versa), the Series 18 features all wetted parts of PTFE Tubing and connections between discrete valves are eliminated and dead volume is reduced. Repeatability and rapid response time make the Series 18 ideally suited for controlling small percentages of low flow liquids.

Features
• Provides unsurpassed chemical compatibility for a wide range of media with all wetted parts of PTFE .
• Low internal volume for reduced delay volume
• 100% continuous duty rating in ambient temperatures up to 66°C
• Low power for reduced heat generation and power consumption
• Fast response times for accurate, repeatable results
• Symmetrical design ensures fluid path length and timing is identical for each fluid channel
• 100% tested tight leak rate provides assurance of a quality seal
• Provides reliable operation for the life of your instrument
• RoHS compliant.

Typical Applications
• Liquid Chromatography Gradient Generation
• Liquid Selection and Mixing Valve
