Puradisc FP-30 30mm syringe filters are designed for the quick and efficient filtration of aqueous solutions. The syringe filters are produced from pigment free polypropylene and have standard inlet and outlet Luer connectors. Devices are available with a choice of membrane or glass microfiber filter media for wide sample compatibility. The media are sealed into the unit without the use of adhesives to eliminate potential sample contamination. Cellulose acetate (CA) membranes have an extremely low binding capacity for proteins. They are mainly used for the filtration of aqueous solutions. The ready-to-use Puradisc GW 30 with pre-rinsed, hydrophilic cellulose acetate membrane has been specially developed for sample filtration in trace analysis. Regenerated cellulose (RC) membranes have an excellent chemical resistance to organic solvents and can be used for the purification of both aqueous and organic solutions. Polyamide (PA) membranes are suitable for the sterile filtration or purification of alkaline solutions. Cellulose nitrate (CN) membranes are versatile membrane filters for the filtration of aqueous solutions.
