All of these filters come with an asymmetric polyethersulfone (PES) membranes.

• Graduated upper chambers hold from 150 to 1000 ml
• Asymmetric PES membrane is an extremely clean, low-extractable, fast-flowing membrane
• Provides excellent throughput and low protein binding of media and other solutions
• 0.2 µm pore size membrane provides a last line of defense against bacterial contamination
• 0.1 µm pore size membranes also protect against mycoplasma contamination
• 0.45 µm pore size membranes are suitable for particle analysis, scintillation counting, prefiltration of aqueous solutions, and general cytology

Complete units come with a bottle-top filter and a receiver storage bottle. Bottle-top filters have side arms fitted with quick-disconnect tubing adapters and screw securely into 33 or 45 mm neck size bottles.
