Project Description

We are seeking a contractor to design and build a simple, miniature active heating circuit using power resistors, a thermistor and AA batteries. The purpose is to maintain a 200uL PCR tube containing fluid between 10-20 degC in an insulated pocket in the minimum ambient temperature of -10deg for 24 hours. The circuit needs to be small, roughly 1" x 1" not including batteries. Insulation material will be provided. No active cooling is required.

The contractor will be responsible for layout, assembly and testing of several prototype units, material costs will be covered by Triomi. Deliverables include schematics, gerbers, and a tested prototype ready for manufacture. It is a very simple design concept. Thanks for your bid!
