Pellicon 2 Microfiltration Modules

Description
Pellicon 2 modules set a new standard in cassette style tangential flow filtration devices.
This series of devices include the popular Durapore range of membranes for microfiltration applications offering pore sizes from 0.1 to 0.65 µm.

To further allow full optimisation of process development and system sizing, we now offer a variety of channel configurations to suit low and high viscosity applications. Select C-screen for low to intermediate and V-screen (open channel) for high viscosity products.

Each module is 100% integrity tested.

Typical Applications

- Protein Solutions
- Polysaccharide Solutions
- Virus Suspensions
- Pre-Column Streams

Sample Prep Syringe Filters

25 mm Millex Filter Units
Syringe-driven filter units with PVC housing
Millex syringe-driven filter units are available in 0.22, 0.45, 0.8 and 5.0 micron pore sizes with PVC or Eastar copolyester housings. Membranes available include glass fiber AP20, MF-Millipore (mixed cellulose esters), Durapore (PVDF) or Millipore Express (PES).

25 mm Automation Compatible Filter Units
Filter units specifically designed for automated applications
High density polyethylene housing and a wide choice of membrane types, with or without prefilter, to fit any application need.

33 mm Non-sterile Millex Filter Units
Almost 20% more surface area than 25 mm filters
Non-sterile Millex filter units are now available in a new, larger 33 mm housing with Millipore Express PLUS (PES), Durapore (PVDF) and nylon membranes.

IC Millex Filter Units
13 mm and 25 mm low-extractable filters specifically designed for ion chromatography
IC Millex filter units are available in both 13 and 25 mm diameters. The 13 mm units are recommended for filtering volumes from 1 to 10 mL. The 25 mm units are recommended for filtering volumes from 10 to 100 mL.
