Valves

A built-in position sensor allows the S 6020/6120, a stainless steel/ PEEK respectively 2-position valve with a needle injection port on the front side, to begin data collecting exactly at the injection site.

Features:

• Heating
• Heating/Cooling
• Temperature Time Program
• Integrated Valve
• Leakage Sensor
• Temperature Fuse

The S 6020 is a stainless steel 2-position valve with a needle injection port on the front side. The S 6120 is an identical valve with an inert PEEK stator. These valves feature the No-Flow-Interruption (NFI) technology which reduces pressure spikes during position switching to a minimum. The needle port can be used with standard microliter syringes (e.g. Hamilton) or plastic-type syringes with 0.7mm needles. The S 6020/6120 has a built-in position sensor for starting data acquisition precisely at the point of injection. A variety of rotor seal materials are available to cover any type of application.
