TheQuick-Stop Luer Check Valve is designed toprovide inline luer
connect/disconnect conveniencewithout themess and hazard of
spills. Just connect the valve assembly to your inline tubing using
standard 1/4-28 flat-bottom fittings (see pages 22–29). The check
valve is automaticallyopenedonce the luer connection is engaged,
allowingflow ineitherdirection.Disconnecting the luer unioncauses
the check valve to close. Please see the “ApplicationNote”on this
page for specific ideas regardinguseof this valve.

Inlet Solvent Reservoir:
Quicklychange your solvent on the lowpressureendof anHPLC
system,whilepreventingpotentiallyhazardous spills! Just install a
Quick-StopLuerCheckValveAssemblybetween your solvent reservoir
and thepump,with the valve towards thebottle. The valvewill prevent
solvent leakage from the linecoming from the reservoir,while thecheck
valves in your pumpprevent spills from the line leading to thepump.
Withboth lines still full of solvent, this systemalsohelps reduce the
need to reprime yourpump.
FIASample Injection:
TheQuick-StopLuerCheckValveprovidesapracticalmeans to
introducea sample intoFIAandother lowpressure systems,whenused
inconjunctionwithaP-612PressureRelief ValveTee (page154). Simply
connect theTee into theappropriateflowpath linewith the included
fittingsand thread theP-697Quick-StopLuerValveonto the1/4-28male
endof theTee. Samplecan thenbe introducedconvenientlybyusinga
standard luer-tipped syringe. Thecheckvalve isautomaticallyopened
when the syringe isattachedandclosedwhen the syringe is removed.
PostColumnDerivitization:
For post-columnderivitization, placeaCV-3000 InlineCheckValveon
theeffluent sideof your column topreventderivatizingagents from
flowingbackwardsandpoisoning thecolumn. Placement on thepost-
column reagent linewill alsopreventmobilephase fromcontaminating
the reagent if theauxiliarypump fails.
HeliumSpargingTankProtection:
Try theCV-3010Assembly, designed specifically fordegassing
(sparging) lines toprevent solventbackup if the sparginggas runsout.
This check valvewill helppreventpotential solvent cross-contamination
anddamage to thegas regulating valve.
