Units are color coded by membrane type (CA: Orange; NYL: Red, CN: Blue; and PES: Yellow). Choice of membrane media: Cellulose acetate (CA), for low protein binding. Nylon (NYL), for low extractable. Cellulose Nitrate (CN), for general purpose filtration. Or polyethersulfone (PES), for fast flow rates and low protein binding.

Membranes come in 0.20, 0.22 or 0.45 µm pore sizes. All four-type membranes are detergent-free, tissue culture compatible, and heat-sealed to the support grid to maximize flow rate, reduce foaming and protein denaturization.

Ordering information: The unit includes membrane filter, glass fiber pre-filter and graduated funnel of clear polystyrene with polyethylene neck adapter. Systems are individually packed, gamma irradiation sterilized and certified non-pyrogenic. Comes with tubing adapter that fits most vacuum hoses.
