Abstract
A microfluidic product pouch assembly may be used in a microfluidic chip. The microfluidic product pouch may include a pouch surrounding an inner chamber and having a rupturing portion and an inner membrane positioned within the inner chamber. The inner membrane may separate the inner chamber into a first cavity and a second cavity. A reagent may be positioned within the first cavity and/or the second cavity. The microfluidic product pouch assembly may also include a rupturing structure. The rupturing structure may be configured to selectively break the rupturing portion of the microfluidic product pouch.
