A method for heating and temperature controlling test samples with a microwave oven has a concentric heat transfer block and microwave transparent screen and viewing holes for temperature measurement

摘要

The test sample (6) is positioned on an electrically conductive cylindrical heating block (4) surrounded by a cylindrical ceramic screen (3), transparent to microwaves, and a cap (5) having an aperture (8) by which infrared or spectroscopic temperature measurement instruments can monitor the test sample temperature. A similar arrangement (7) may also be provided.
