Abstract
A heatable pipette apparatus, includes a pipette tube having a first zone and second zone. The first zone includes a tip end and a first heater for heating the first zone. The second zone includes a second heater for heating the second zone. Regulators are provided for separately regulating the temperature of the first heater and the second heater, the first heater being able to more accurately and precisely alter the temperature of fluids in the tube to reach a predetermined temperature.
