HAMDEN, Conn., Jan. 8, 2013 — Warner Instruments is offering Okolab’s T Plates, round heated plates with a built-in touch-screen interface temperature sensor. The flat-surface devices are compatible with any microscope, including inverted types. They are suitable for use in short-term experiments and available in glass and metal versions. The T Plate fits into microscope X-Y stages with circular openings and provides a transparent surface at a controlled temperature. The conductive glass has a temperature sensor and, when coupled with the proportional integral derivative temperature controller, provides accuracy of ±0.3 °C on specimen temperature. The controller features an external temperature sensor for the self-calibration routine, two temperature channels and an optional zero footprint mount.
