FT18MkII Modular Cross Flow Filtration

Der Armfield FT18-MkII ist ein kleines Pilot-Cross-Flow-Filtrations-System, welches für den Einsatz mit einer Reihe von Membran-Modulkonfigurationen ausgelegt ist. Es kann mit schon mit 5-10 Liter Material arbeiten, liefert aber immer noch Daten, die für Prozess-Scale-up nützlich sind. Es kann über die gesamte Bandbreite der Querstrom-Filtrationsanwendungen von der Mikrofiltration bis zur Umkehrosmose eingesetzt werden. Es ist das perfekte Werkzeug für weitere Prozessentwicklung und Scale-up nach den Membranversuchen mit dem Gerät FT17.


• Dual operation, RO/UF
• Uses proprietary membranes available from PCI
• Clean-in-place (CIP) facility
• Mobile and self-contained operation
• Computer linked for data logging and analysis


> Rapid changeover from R0 to UF and back
> Easily cleaned and maintained

Vessel (FT18-20)

30-litre 316 stainless steel retentate vessel for recirculated product, complete with sensor to protect against dry running. Mass balance option for permeate flow rate measurement.

Electronic Flow Meter (FT18-44)

  • Electronic flow meter that measures the recirculation (retentate) flow rate
  • Must be ordered with FT18-MkII base unit

Backpulsing/Backflushing (FT18-50)

  • This module enables filtration pressure to be reversed for a period of time during processing in order to reduce fouling and thus enable extended operation between cleaning cycles
  • This module is compatible with the Ceramic (FT18-5) and Hollow Fibre (FT18-7) filter modules only
  • Must be ordered with FT18-MkII base unit

System Control

  • As standard the system is controlled by a PC (not supplied) with a USB interface
  • An optional touchscreen system (FT18-60) can be used in place of a PC (not supplied)
