Sterlitech Sepa
CF II Membrane Cell System
Sepa CF II Membrane Cell System is
a lab scale cross-flow membrane filtration unit that provides fast
and accurate performance data with minimal amounts of membrane,
product, expense, and time. Its unique patented* design simulates
the flow dynamics of larger, commercially available membrane elements.
Users can vary the operating conditions and fluid dynamics over
broad ranges. Whether used as a membrane evaluation device, process
development tool, or for small-scale production, the Sepa CF II
Membrane Cell System from Sterlitech has the features and benefits
that today’s users demand.
*Patent #4,846,970
The Sepa CF Cross-flow membrane holder is recommended for water
studies, paint, biotechnology, cell harvesting, plasma concentration,
separations, food and beverage applications and membrane studies
for just a few of the versatile uses for this small-scale industrial
unit. It provides fast and accurate performance data for production
scale-up of any reverse osmosis, nanofiltration, and ultrafiltration
or microfiltration crossflow application.
This system is also ideal for testing membranes. The unit accepts
any flat 19 cm x 14 cm (7.5 inch x 5.5 inch) membrane for a full
155 cm^2 (24 in^2) of effective membrane area. The hold up volume
is 70 mL.
The holder can be operated in laminar flow to minimize denaturation
of sensitive solutions, or in turbulent flow to maximize membrane
life. A stainless steel concentrate flow control valve mounted on
the concentrate outlet of the cell provides accurate control of
pressure and flow over the membrane surface.
The cells are available in 316 stainless steel for use with high
temperature and aggressive chemicals. We offer wastewater, processes,
or a low foulant unit for pure water. The medium/high foulant unit
is for wastewater and viscous solutions. The pressure rating (maximum)
is 69 bar (1000 psi).
A pneumatic or hydraulic operated mechanism quickly closes and seals
the cell. This provides uniform pressure on the membrane to assure
a perfect seal. Compare this to ordinary time-consuming multiple
bolt closures with their inherently uneven torque and leak problems.
Special feed flow pumps are not required. Most standard laboratory-scale
peristaltic, diaphragm, or centrifugal pumps are suitable for use.
The connections are ¼-inch FNPT to the Feed (Concentrate)
and Pneumatic/Hydraulic Port for the Piston. The permeate hose fittings
has 1/8-inch FNPT connection.
Sterlitech Corporation also offers ready-made, individually wrapped
membrane in single or assortment packs, for your needs. Please call
Sterlitech customer service (1-877-544-4420) for additional information
on this product and the membranes.
