AcroPak™ 20 capsule filters are designed to efficiently process up to 2 litres of chemical and biological fluids. These filters are available in three different membrane types.

Supor®
The Supor® membrane has high flow rates and throughputs, and is ideal for solutions where low protein binding is required. Not recommended for use with some ketones. For sterile filtration of media and buffers.
• Built-in prefilter extends filter life when particulate-laden solutions such as serum-containing media are processed
• Sterilisation by gamma irradiation eliminates potential contamination by EtO residuals
• PP housing and vent plug, PC filling bell, Supor® (hydrophilic PES) membrane
• Suitable for use with fluids containing dilute proteins, preservatives, or other critical components

Supor® EKV
Built-in MachV asymmetric pre-filter layer for maximum flow and throughput performance. For Sterile filtration of media and buffers.
• Disposable for reduced labour and associated costs
• Significantly reduces the cost of repeat testing when scaling up your filtration system
• Ideal for filtering aqueous solutions, cell culture media and serum
• Suitable for use with fluids containing dilute proteins, preservatives, or other critical components

Fluorodyne® II
The Fluorodyne® II membrane is compatible with aqueous and many organic solvents.
• Double layer sterilising membrane enhances reliability
• Upstream air vent prevents vapour lock
• Manufactured without the use of adhesives to minimise extractables

Supor and Supor EKV can withstand one autoclave cycle at 125 ºC (257 ºF) for 60 min; water wet capsule prior to autoclaving. Fluorodyne II can withstand one autoclave cycle at 131 °C (268 °F) for 30 min.
