- Vaccines

- Serum, plasma fractions and other blood products

- Tissue and cell culture media

- Protein solutions

- Fermentation media and feeds

- Cell removal from fermentation broth

- Pre-column chromatography

Features

- Nominal ratings from 0.2 µm to 99 µm 

- Self-bonded, non fiber-releasing filter media

- All-polypropylene construction

- Ultraclean – no binders, adhesives or surfactants

- High flow rates

GFguard® Glass Microfiber

An advanced borosilicate glass fiber pre-filter removes particulates and reduces bioburden in biological liquids

Glass fiber depth filters are designed for removal of contaminants like colloids, lipids, protein aggregates and particles from biopharmaceutical fluids. They are used for protection of membrane filters, chromatography columns and ultrafiltration systems in pharmaceutical and biotechnological production processes.


Applications

- Cell Culture fluids after cell harvest

- Fermentation broths 

- Serum free or serum containing cell culture media 

- Serum 

- Highly viscous ophthalmic and LVP solutions 

- All media containing lipids and colloids as contaminants


Extractables
GFguard cartridges meet, or exceed the requirements for WFI quality standards set by the current USP.
