Our re-design is based upon the Open PCR system originally designed by Josh Perfetto and Tito Jankowski.
System Design
New Lid Catch
Key Features
The redesigned version of the Open PCR system focused on resolving the issues that surrounded the function of the Open PCR machine's lid. One modification made was the changing of materials used in production of the PCR lid. In the original design of this machine wood was the main structural material of the Open PCR's lid; however,this redesign changes the material used on the sides of the lid from wood to plexi-glass. The use of plexi-glass allows for the user to see into the lid of the Open PCR machine.In turn allowing the user to view the height of the heat plate while adjusting it, this then minimizes the the chance of the user crushing the DNA samples while lowering the heat plate. The other modification present in the redesign was that the magnetic clasp from the original design was replace by spring catch. The original magnetic clasp on the PCR required too much force to open. While this magnet prevented the lid to open mistakenly during an experiment, it made the machine vulnerable to breakage when the lid needed to be opened. The newly added catch provides the same amount of protection in terms of mistaken lid opening but it also increases ease of use and limits the chance of breakage while opening the lid.
