Diagnostic Cartridge

Tasks:  

• Revise cartridge design to improve flow mechanics and minimize bubble entrapment in the imaging zone


• Identify transparent material compatible with imaging, reagents and high temperature


• Develop cartridge assembly method that is compatible with extreme temperature cycling


• Develop assembly method to create a membrane seal that resists high temperature and pressure

Unique Features/Challenges:

• Product required laser/ultrasonic weld around the perimeter of all flow channels to withstand the high temperature/pressure and reagents required by the application


• Our extensive materials experience allowed us to specify a unique material which meets all mechanical requirements and has superior clarity for imaging


• Developed method to ultrasonically  weld membrane material to the top housing


• Developed sample well geometry which minimizes the potential for bubble entrapment
