PDMS Membranes
PDMS membranes are polymeric films prepared from polydimethylsiloxane. Due to the characteristics of polydimethylsiloxane materials, PDMS membranes are endowed with certain specific properties, such as elasticity, excellent gas permeability, full transparency, biocompatibility, and so on. Therefore, they are quite valuable in microfluidic systems. Due to the permeability of PDMS, the films can be used to exchange gases or small molecules between two liquids or gases and liquids without direct contact. In addition, due to the elasticity of PDMS, the membranes can be used to fabricate valves in microfluidic chips.
Alfa Chemistry offers a range of PDMS membranes that are well suited for building microfluidic systems and cell culture systems. Moreover, our PDMS membranes can be used in combination with other materials (e.g., nanomaterials, metallic materials, etc.) to form more complex assemblies that can be used to realize more sophisticated cell culture and microfluidic operations.
