Flow Cell for Nanofiltration (NF) Mem...

$799.00

A Lab-Scale Membrane Testing System is a benchtop apparatus used to evaluate flat-sheet membrane coupons or small hollow-fiber modules. It determines core transport and separation properties—such as pure water permeability (PWP), solute/salt rejection, molecular weight cut-off (MWCO), and fouling resistance—across Microfiltration (MF), Ultrafiltration (UF), Nanofiltration (NF), and Reverse Osmosis (RO) regime.

There are two main configuration systems: (1) Cross-Flow (Tangential Flow) System: Feed solution flows tangentially across the membrane active layer at a controlled cross-flow velocity, continuously sweeping away accumulated foulants. High-pressure feed pump (diaphragm or gear pump), backpressure regulator valve, cross-flow cell with feed spacers, heat-exchange cooling coil, and automated permeate mass balance. It is best for NF, RO, Forward Osmosis (FO), and long-term anti-fouling evaluations. (2) Dead-End Stirred Cell (e.g., Amicon-type): Feed is pushed perpendicular to the membrane surface using pressurized gas (N2 or compressed air) while an internal magnetic stir bar minimizes concentration polarization. It is best for rapid screening of MF/UF membranes, MWCO determination (using dextran/PEG standards), and protein concentration.

Part Number	CFMECLSTS (C-FME-CLSTS)
Power	AC110V-220V±10% (DC24V adaptor), single phase, 50/60Hz, ~50 W
General Features	Pressure gauge is installed for pressure monitoring Automatic pressure adjustment with intelligent pressure increment pump Water and electricity sections are well separated for improving safety
Operation Procedures	Before incorporating the membrane core into the testing system, use tap water (>10 L) to flush the filtration tester. If the sourcing water has a TDS value >1000, a pre-filtration pressurization unit should be used to avoid block of membrane Rotate the ball valve of concentrated water to adjust the water flow and pressure. UF: 1-3 kg/cm2; NF and RO: 4-8 kg/cm2
Testing System Structures	Front View: The testing system was mainly composed of membrane core chamber, intelligent pressurization system (100G pump) and pressure gauge. Back View: The power plug port and on/off button, water inlet/outlet ports, and concentrated water outlet are presented at the backside.
