Sterlitech CF042D Delrin Crossflow Filtration Cell

High-Pressure Laboratory Crossflow Cell for Membrane Testing and Process Development

The Sterlitech CF042D is a laboratory-scale crossflow filtration cell manufactured from durable Delrin® (acetal copolymer) and designed for evaluating flat sheet membrane performance under realistic operating conditions. Featuring a 42 cm² active membrane area and support for pressures up to 69 bar (1000 psig), the CF042D enables researchers and process engineers to generate reliable membrane performance data while using minimal feed volumes and membrane material.

By replicating the hydrodynamic conditions found in larger commercial membrane systems, the CF042D provides an effective platform for membrane screening, process optimisation, fouling studies, and scale-up development. The Delrin construction offers excellent mechanical strength and chemical compatibility for a wide range of aqueous and process streams, making it suitable for microfiltration, ultrafiltration, nanofiltration, and reverse osmosis applications.

Key Features

  • 42 cm² active membrane area

  • Delrin® (acetal copolymer) construction

  • Maximum operating pressure of 69 bar (1000 psig)

  • Low 17 ml hold-up volume

  • Suitable for flat sheet membrane testing

  • Compatible with a wide range of membrane processes

Designed for realistic process simulation
The CF042D reproduces the flow conditions encountered in commercial membrane systems, enabling accurate evaluation of membrane performance, flux rates, rejection characteristics, and fouling behaviour.

High-pressure membrane testing
With an operating pressure rating of up to 69 bar (1000 psig), the CF042D is suitable for demanding nanofiltration and reverse osmosis research applications as well as lower-pressure membrane processes.

Efficient use of samples and membranes
The compact 42 cm² active area and low hold-up volume minimise feed solution requirements, reducing material consumption during membrane development and screening studies.

Durable Delrin construction
Manufactured from acetal copolymer, the CF042D combines excellent mechanical strength with broad chemical compatibility, making it a dependable choice for routine laboratory membrane testing.
