Vacuum Filtration Systems

Nest disposable vacuum filtration system is useful for large volume sample separation and sterilization for tissue culture media and other biological buffers by using a vacuum pump to provide differential pressure for the filtration.

• High flow rates and flux
• Low protein binding and low chemical extractable
• Non-Pyrogenic, DNase/Rnase free
• Sterilized by E-beam, SAL=10⁻⁶
• Individually packaged in sterile bag
• Hydrophilic

The units include PES or PVDF membrane filters with graduated filter tops made with polystyrene, and Acrylonitrile-Butadiene-Styrene necks with polystyrene receiving bottles. A separated sterile polyethylene cap is included.

Filtration system is manufactured from raw material of high transparency polystyrene (PS) in three different volumes: 250, 500 and 1000 ml. They are available in three styles: Complete filter/storage bottle systems, bottle top filters, and receiving bottles only.

PES application direction: For general culture media and aqueous solutions, polar or middlepolar solvents, neutral aqueous solutions.
PVDF application direction: May be used for aqueous solutions and most solvents, including strong non-polar solvents. Ideal for preparations of HPLC and GC.

The product has been irradiated and dosimetrically released based on ANSI/AAMI/ISO 11137.
