Contract Manufacturing

Whether it is thousands of units or millions of units, the true power of a product lies in its ability to spread widely and change people's lives. If you need dozens or hundreds of microfluidic devices for product testing or verification, Alfa Chemistry can help you. We use a quality management system (QMS) to enhance the reliability of our products.

The manufacturing, processing, and packaging of microfluidic products are carried out in our standard cleanroom facilities. All tools, molds and fixtures are manufactured in-house to speed up turnaround time and protect customers' IP.

Our Manufacturing Capabilities

Device Materials

Alfa Chemistry has the core expertise and know-how to manufacture microfluidic devices made of various material systems. The materials we use for microfluidic chip manufacturing include:

  • Polydimethylsiloxane (PDMS)
    PDMS is the most widely used silicon-based organic polymer and is known for its extraordinary rheological (or flow) properties. It is optically transparent and is generally inert, non-toxic and non-flammable. PDMS chip is currently the most widely used platform for microfluidics.

  • Thermoplastic
    PMMA-polymethyl methacrylate, also known as acrylic glass or plexiglass.
    PS-polystyrene, a common plastic used for cell culture vessels.
    COC-cyclic olefin copolymer, thermoplastic polymer.
    COP-cyclic olefin polymer, a thermoplastic polymer.
  • Glass PDMS
    Since PDMS parts have rubber-like mechanical properties, they are not rigid enough for handling. Therefore, PDMS parts are usually bonded to glass microscope slides or thin glass coverslips, or even custom-sized glass substrates. We have special expertise in bonding and sealing PDMS parts to glass and various other substrates used to make glass.
