NGS library preparation can be a time consuming, arduous process. This system design addresses the creation, extension, exo and PCR assembly processes within the library preparation. The client can perform one continuous protocol or break up the workflow into single segments thus allowing for interleaved protocols depending on their current workload requirements. The system’s SteriStore is used as an oven to cook DNA. For precious reagents such as Mastermix, the system incorporates a low dead volume dispenser to reduce cost and waste.
