Gas sample loops
A 0.25 mL sample loop is included with all gas sampling valve
systems. 10 mL and 5 mL loops occupy one valve position,
limiting the number of valves that can be housed in a valve
compartment.
Adjustable restrictor valves
Adjustable restrictors are used to balance flow resistance
between the two valve positions. They are available with ambient
to 225°C (part no. 0101-0633) or ambient to 350°C (part no.
0101-0948) operating ranges.
