MANUAL INJECTION VALVES
Series 3725i-038 and 3725i Preparative Injection Valves
The series 3725i-038 (stainless steel) and
3
725i (PEEK) are the most suitable manual
valves for large sample volumes, high flow
rates, and preparative columns sized
1.0-10 cm in diameter.
●
Versatile ports accommodate 1/8″
(
3.2 mm) and 1/16
″ (
1.6 mm) OD tubing.
(Note: 1/16
″ OD tubing requires an
adapter, PN 5067-1503.)
●
1.0 mm diameter passages allow flow
rates up to 800 ml/min with virtually
no pressure drop.
●
Make-Before-Break technology allows
switching without flow interruption.
●
High reproducibility for both partial-
fi
lling and complete-filling methods.
●
Sample range is 100 µl to 20 ml
(10 ml loop is installed).
●
Flow range is 10 to 800 ml/min.
●
Built-in position sensing switch
gives the chromatograph a
reproducible start signal.
