Chromatodisc Sample Syringe Filters

GL Sciences’ Chromatodisc syringe filters have provided chromatographers worldwide with predictable, reproducible sample filtration for over 20 years.   

Three basic filters types are available.Type "A" refers to a hydrophilic polyolefin membrane encased in a polypropylene housing and used for highly aqueous (water soluble) samples, particularly proteins and peptides. 
 
Type "P" is to a hydrophilic PTFE membrane in a polypropylene housing and used for pharma applications on small organic molecules dissolved in pure organic or aqueous / organic solutions.  Type "P" filters have a convenient property of not-needing pre-wetting of the membrane prior to filtration.   Type P are our most commonly used Chromatodisc sample filters.

Type "N" is characterized by a hydrophobic PTFE membrane encased in polypropylene housing and used for (mainly) non-polar samples dissolved in neat organic solvents or strong acids and bases.  Type "N" filters are the most durable, chemically-resistant of the Chromatodisc line.

Chromatodisk filters are available in 0.2 micron and 0.45 micron pore sizes in 4mm, 13mm, and 25mm membrane diameters.
