Decades of experience in sterile production has lead PSL to develop unique aseptic filtration solutions for microsphere made drug delivery formulation from small scale processes up to large scale production.
Decades of experience in sterile production has lead PSL to develop unique sterile filtration solutions for microsphere formulation from small scale processes up to production.
Microspheres are small spherical particles, having a required size range (typically 5μm up to 250μm). These particles can be manufactured from various natural and synthetic materials such as polymer microspheres. New applications for microspheres are discovered every day from coating to cosmetics and cancer research. PSL develops solutions mostly used for drug delivery, as biodegradable polymer microspheres can work as miniature time release capsules for parenteral drugs within pharmaceutical and biotechnology industries.
Suspended microspheres obtained from various micro encapsulation processes require unique handling that differ from a typical filtration and drying operation. Following the synthesis stage, microspheres require being washed, collected by filtration then dried under appropriate conditions to give the final free flowing injectable or inhalation microsphere product. Microspheres are random in size and need to be filtered and classified into the micron size desired before drying. PSL sterile filter dryers have been designed to meet such criteria suitable for washing, filtering, classifying and drying with aseptic and complete product recovery.
