1-16 Introduction
Automated plunger seal wash
The plunger seal wash system is an optional accessory for all 1500-series
pumps. The seal wash solvent lubricates the plunger and flushes away any
solvent or dried salts forced past the plunger seal from the high-pressure side
of each piston chamber. This wash cycle extends the life of the seals. For
installation instructions, see page 3-17 .
Once the pump is powered-on and seal wash pump is primed, the plunger seal
wash system operates automatically (see page 4-8 ).
Manual injector
An optional manual injector allows you to manually control sample injections
during a run. This technique is useful with preparative or semi-preparative
HPLC applications.
Waters offers two different model manual injectors for the 1500-series pumps:
• 1500-series manual injector
• FlexInject manual dual injector
The 1500-series manual injector is supported on all 1500-series pumps except
the 1525µ
. Ι
t consists of a single injector valve that you can install and use to
perform precise manual sample injections.
The FlexInject manual dual injector operates with any fluid-mixing system,
including 1500-series pumps. It allows you to inject small or large sample
volumes by simply selecting a valve.
The FlexInject injector can operate with flow rates as high as 150 mL/min and
mounts on either side of the 1500-series pump for easy access. Its two sample
injectors are pre-mounted along with a selector valve, which diverts the flow
to small- or large-scale sample preparations. You can connect analytical as
well as preparative columns to the respective injector.
For instructions on installing the 1500-series manual injector or the
FlexInject manual dual injector, see page 3-4 .
Ethernet communications kit
For help with HPLC Ethernet connections, you can order from Waters the
Ethernet Switch Communications Kit (part number 700004123). The kit
includes an 8-port Ethernet switch, cables, and a mounting bracket, for
mounting the switch on the rear panel of the 1500-series pump or separations
