High efficiency, all-polypropylene depth filters for use in Active Pharmaceutical Ingredients (API) processes

An Introduction to Q Grade

The application of Good Manufacturing Practices (GMP) within Active Pharmaceutical Ingredients (API) processes as described in the ICHQ7A guidance document is becoming increasingly important.颇尔® Q Grade cartridges are high quality, economical filters aimed specifically at applications within API processes.These products are supplied with a’Q’ certificate of quality, incorporating essential product and manufacturing quality details.

Nexis A filter cartridges (Q Grade) are high efficiency, all-polypropylene depth filters produced by advanced melt blowing technology.Products in this range have an exceptionally stable matrix comprised of a continuous pore gradient of microthin fibers intermingled with large diameter support fibers.This proprietary CoLD (Co Located Large Diameter) structure results in highly effective contaminant removal combined with long on-stream life, particularly when a wide distribution of particle sizes may be present.
