Biocompatible and inert
Low swept volume
Pressure rated to 500 psi (34 bar), ceramic version and
1,000 psi (69 bar), polymer version
The Upchurch Scientifc
®
6-Port Medium Pressure Injection Valves
feature easy, external sample loop customization. Simply clean-cut a
piece of tubing that represents the volume of sample you wish to inject,
taking into account the port-to-port volume of the valve. Please refer
to the “Tubing Internal Diameters and Volumes” chart on page 198
for assistance in calculating the volume of a length of tubing.
Two biocompatible injection valve options are available:
Long-Life Ceramic
Featuring ceramic-to-ceramic sealing surfaces, these long-life valves
have been tested to over one million actuations with no change in
performance.* The wetted materials are chemically resistant ceramic
and PEEK
™
polymer and the valves are rated to 500 psi (34 bar). Each
valve includes 1/4-28 Flangeless Fittings for 1/16” OD tubing.
Economical Polymer
These economical valves have chemically resistant Vespel
®
and
PTFE resin wetted surfaces and are rated for a maximum pressure of
1,000 psi (69 bar). Each valve includes 1/4-28 Flangeless Fittings for
1/16” or 1/8” OD tubing.
Both valve opt ions are avai lable in three conf igurat ions:
standard manual, bulkhead mountable manual and actuated.
Valves can be premounted on a DC gear motor actuator to
automate valve positioning. Each actuated valve is provided
with an inl ine power adapter which al lows operation from
110/120V and 220/240V AC power, a RS-232 and contact closure
communication cable and a cable for multiplexing valves in series.
