Back Pressure Regulator Cartridges 

- Proven outgassing protection 

- Flow-independent pump preload for greater pump efficiency 

- 5 to 1,000 psi cartridges and assemblies available 

Back Pressure Regulators are designed to enhance system performance through outgassing prevention and improved pump check valve efficiency. 

IDEX Health & Science back pressure regulators include: 

- 5 and 20 psi assemblies (replacement cartridges not available) 

- 40, 75, 100, 250, 500, 750, and 1,000 psi cartridges and assemblies

- PEEK and stainless steel BPR holders

- High pressure adjustable BPR for pressures between 2,000 and 5,000 psi

- Ultra low volume BPRs set to 100 and 500 psi (page 146) For flow control options try the Micro-Metering Valves found on page 143.

Back Pressure Regulator Replacement Cartridges 

- Materials of construction: PEEK, ETFE, perfluoroelastomer, 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 flow except as noted below. The recommended operating flow 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 flow rates may result in larger pressure fluctuations.
