P-465 PEEK andU-469 Stainless Steel BPRHolders
work with any of our replacement BPR Cartridges. Each holder comes
with fttings for 1/16” OD tubing (see below). The U-469 Holder is
surface-treated to prevent galling, a potential problem with large,
threaded metal parts.
Please Note: These Back Pressure Regulator Holders are designed
to allow each cartridge to operate at its stated pressure setting when
tightened to 20 in–lbs. of torque. To approximate this level of torque,
frst fnger tighten the Holder, then tighten an additional 1/8 –1/4 turn
with the supplied wrenches.

, ETFE, perfuoroelastomer,
and gold-plated stainless steel
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 fow except as noted below.
The recommended operating fow rate range for our BPR Cartridges
is 0.1 mL – 10 mL/min. Within this range, the amount of back
pressure created by the BPR Cartridges and Assemblies will not
vary more than ±10%. Lower or higher fow rates may result in larger
pressure fuctuations.

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% fuctuation in pressure generally occurs with fow rates of 0.1 –
10 mL/min. Lower or higher fow rates will lead to greater fuctuations
in pressure. To achieve the desired back pressure setting, simply
turn the thumbscrew while monitoring your system pressure.
Because this product creates such high back pressure, please check
system component specifcations prior to using to avoid damaging
any sensitive components.
