Description
Ports on the front of the Workstation:
a.
Pumphead Inlet ports: Buffer inlet lines attach to the bottom of each
pumphead using standard 1/4-28 flat-bottom fittings. The pumphead inlet
tubing is 1/8” (3.2 mm) OD, 0.062” (1.6 mm) ID
PTFE tubing with flat bottom
fittings which are supplied in the Fittings kit.
b.
Pumphead Outlet and Pressure Transducer Inlet and Outlet ports: All
plumbing following the pumphead outlet ports uses standard 1/4-28 flat-
bottom fittings and the following tubing:
Orange PEEK tubing: 1/16” (1.6 mm) OD, 0.020” (0.51 mm) ID. Used with
pressures up to 5000 psi.
Green PEEK tubing: 1/16” (1.6 mm) OD, 0.030” (0.76 mm) ID. Used with
pressures up to 3000 psi, usually for flow rates greater than 20 ml/min.
c.
Pumphead Priming ports: This port on each pumphead is used to prime the
pump. The port accepts any size syringe with a luer fitting; a syringe is
included in the Fittings kit. This draws buffer through the inlet line and to the
pumphead. Twist the port counter-clockwise one turn to open it.
d.
Pumphead Washout Inlet ports: The port on top of each pumphead is used
to rinse the piston to remove crystallized salts. It accepts any syringe with a
luer fitting. A syringe for this purpose is included in the Fittings kit. The rinse
output is the open trough between the pumpheads. The pumpheads should br
rinsed daily.
