P-465PEEKandU-469StainlessSteelBPRHolders
workwithanyofour replacementBPRCartridges.Eachholdercomes
with fittings for 1/16”OD tubing (see below). TheU-469Holder is
surface-treated toprevent galling, a potential problemwith large,
threadedmetal parts.
PleaseNote: TheseBack PressureRegulator Holders aredesigned
toalloweachcartridge tooperateat its statedpressure settingwhen
tightened to20 in–lbs.of torque.Toapproximate this levelof torque,
firstfinger tighten theHolder, then tightenanadditional 1/8–1/4 turn
with the suppliedwrenches.

These replacement cartridges will operate in any of the standard
BPR holders shown on this page. These cartridges create back
pressures from 40 to 1,000 psi (2.8 to 69 bar)—all independent
of flowexcept asnotedbelow.
The recommendedoperatingflow rate range forourBPRCartridges is
0.1mL–10mL/min.Withinthisrange,theamountofbackpressurecreated
bytheBPRCartridgesandAssemblieswillnotvarymorethan±10%.Lower
orhigherflow ratesmay result in largerpressurefluctuations.

The biocompatible P-880 High Pressure Adjustable BPR offers
the flexibility to adjust your system back pressure between 2,000
and 5,000 psi (138 and 345 bar), independent of the flow. Only
10% fluctuation in pressure generally occurs with flow rates of
0.1–10 mL/min. Lower or higher flow rates will lead to greater
fluctuations inpressure.Toachieve thedesiredbackpressuresetting,
simply turn the thumbscrewwhilemonitoring your systempressure.
Because this product creates suchhighbackpressure, please check
system component specifications prior tousing to avoiddamaging
any sensitivecomponents.
