Membrane Stack Disc Filters
Description
Cost-Effective Filtration of Buffers, Tissue Culture Media, and Other Biological Fluids
- Disposable – Reduces labor costs associated with assembling, cleaning, and testing stainless steel filter holders.
- Flexible – Encapsulated format for ease of use.
- Extended life – Built-in MachV asymmetric prefilter layer for maximum flow and throughput performance.
- Simplified scale-up – Membrane and housing materials are identical to those used in larger-volume capsules and cartridges from Pall Life Sciences.
- Low adsorption and high chemical compatibility – Featuring hydrophilic polyethersulfone membrane for high compatibility over the entire pH range and low protein binding.
- Presterilized – Using gamma irradiation, products are presterilized, non-pyrogenic, and non-cytotoxic (with the exception of 47 mm disc filters).
- Inherently hydrophilic – Provides a reliable integrity test.
- Tested – Passes United States Pharmacopeia (USP) Biological Reactivity Test, In Vivo <88>. Assessed during manufacture to ensure product integrity.
Applications
47 mm Disc Filters

- High throughput
- Low protein binding
- Fast flow rates
Applications
Suitable for sterile filtration of a wide range of fluids, including:- Buffers
- Biological fluids
- Cell culture media
- Ophthalmic products
AcroPak 20 Filters

- Designed to add convenience to small- and mediumvolume filtration
- Generates twice the effective filtration area and double the throughput/flow rate of conventional metal 47 mm reusable filter holders
- Disposable for reduced labor
- Significantly reduces the cost of repeat testing when scaling up your filtration system
Applications
- Ideal for filtering aqueous solutions, cell culture media, and serum
- Small- to medium-volume sterile filtration, typically up to 1 liter
- Suitable for use with fluids containing dilute proteins, preservatives, or other critical components
- Sterile filtration of media and buffers
25 mm Acrodisc® Syringe Filters

- Universal life science membrane with low protein binding to minimize sample loss
- Superior flow rates and higher throughputs than similar devices
- Sterilized by gamma irradiation to eliminate potential contamination by EtO residuals
Applications
- Small-volume applications (such as liquid sterilization and determination of product compatibility and recovery)
- Ideal for typical process volume up to 100 mL
AcroPak 200 Capsules
- High filtration area and compact size are ideal for upscale trials
- Minimal hold-up volume
- Good wettability for reliable integrity test
- United States Pharmacopeia (USP) Biological Reactivity Test, In Vivo <88>
- Sealed membrane and housing uses fusion technology to eliminate potential extractables
- Gamma sterilized, non-pyrogenic, and provided with a removable filling bell (except sanitary flange option)
- Hydrophilic polyethersulfone membrane for low adsorption and wide chemical compatibility
- Very high flow rates and consistently higher total solution throughputs due to superior porosity over other membranes
Applications
- Designed to quickly process difficult-to-filter solutions within 5-21 liters, such as serum, serum-supplemented culture media, and ascites fluid
- Ideal in situations where rapid filtration or short processing times are essential
AcroPak 400, 800 and 1500 Capsules
