PolyHeater™

Dry Sample Thermal Accessory for the MFP-3D™ AFM

The PolyHeater is a thermal accessory that allows controlled heating of dry samples from ambient to 300°C. The PolyHeater is designed for imaging and measurements in ambient air and is ideal for materials science samples such as polymers, thin films and others.

The PolyHeater heating stage is a metal stage embedded in ceramic and high performance plastic. The heating stage can be used with a standard cantilever holder for heating up to 250°C. For experiments between 250° and 300°C, the Asylum Research PEEK™ cantilever holder is also included. Sample temperature can be maintained to better than 0.2°C precision with accuracy to 0.5°C. Typical temperature overshoots are less than 0.2°C.

The sample stage accepts magnetic AFM mounting discs and has clips and threaded holes for other sample mounting methods. Sample mounts of 12mm in diameter are recommended. Sample thicknesses to 2mm are supported. There are four 1/16" ports which can be used for inert gas purging or electrical connections to the sample. The cell can be fully sealed with a membrane that is included with the kit. Thicker samples of 5-10mm are possible when the cell is not sealed. The maximum coarse sample translation is 10mm.

Environmental Controller – Closed Loop Accuracy
The PolyHeater requires the Environmental Controller, a state-of-the-art digital controller (purchased separately). The built-in microprocessor maintains closed loop performance independent of the AFM controller. All control and measurement functions are fully programmable through the software interface, including built-in capability for temperature ramps. Fully integrated temperature information is stored with each AFM image. SmartStart™ allows plug and play operation without the use of parameter files.
