Cell culturing is a fundamental technique used to study and cultivate human or animal cells in controlled environments. It plays a vital role in various fields, such as biochemistry, molecular biology, and drug testing. By cultivating cells, researchers can gain insights into metabolic processes and assess the effectiveness of drugs, vaccines, and therapeutic proteins.

Cell culture inserts from our sister company, Oxyphen, feature UNIQUE-MEM® track-etched membranes, directly bonded to the insert. This unique combination ensures a strong bond between the plastic body and the smooth membrane surface, making them suitable for large inserts and unconventional cell culture formats.  

These customizable track-etched membranes are particularly suitable due to their precise performance parameters. They offer flexibility, allowing you to choose from standard hanging designs or customized inserts based on your specific needs.
