The Tetrad 2 contains an onboard Pentium-class computer that delivers an advanced graphical interfaceideal for managing production-grade thermal cycling. For those labs that value quick training, the creation and editing of protocols can be accomplished rapidly and easily via the mouse-directed point-and-click navigation. Real-time displays of block, sample and lid temperatures provide quality assurance that the thermal cycler is performing as directed. Superior software features, such as error tracking logs, run tracking files, problem resolution trees and file management tools, offer invaluable information for troubleshooting during high throughput runs.
