A microtiter plate system includes an integral heater. In an embodiment, the
integral
heater includes a heater plate. In another embodiment, the integral heater includes
resistive heater wires positioned beneath and/or between the wells of a microtiter
plate. In an embodiment, the microtiter plate system includes optically clear well
bottoms that permit sensing and measurement of samples through the optically clear
well bottoms. In an implementation, an optically clear heater is positioned beneath
the optically clear well bottoms. In an alternative implementation, resistive heater
wires are positioned between the wells. In an embodiment, the microtiter plate
system includes a microtiter plate lid with an integral heater, which can be implemented
using a heater plate, resistive wires, and the like. In an embodiment, the microtiter
plate system includes an integral non-contact heater, such as a ferrous plate and/or
ferrous particles, powder and/or fibers, which generate heat when subjected to
an electromagnetic field. An electromagnetic field can be generated by an inductive
coil or the like. In an embodiment, the microtiter plate system includes an integral
non-contact heater which generates heat when subjected to microwave radiation from
a microwave generator. In an embodiment, the microtiter plate system includes an
integral thermostat that maintains a substantially constant temperature in the
microtiter plate system.
