A temperature-controlled micropipette adaptor (100) includes a metal base (110) sandwiched between two plastic layers (112,114). The metal base has an orifice (120) to hold a micropipette (20). The plastic layers hold lenses (118,116) in alignment for spectrophotmetric measurements of a sample contained in a micropipette inserted into the orifice. A resistive heater wire (138) is held between the metal base and the plastic layer to transfer heat from the heater wire to the metal base and thus to the micropipette sample. A thermocouple (130) is attached to the metal layer to monitor temperature changes. A feedback control system is coupled to the device for monitoring and programmably controlling changes in temperature of the heated sample over time.
