Method for heating a volume of liquid in a heated pipetting needle

摘要

The method involves drawing in desired volume of liquid, and drawing in volume of air. Volume of air is selected such that the volume of liquid reaches region of a heated pipetting needle (1) in which a temperature sensor e.g. thermosensor (5), is mounted and completely passes through the region. The pipetting needle has constant intended temperature. The temperature sensor only activates the heating device if the intended temperature is undershot. Drawn-in volume of air and liquid are dispensed. Independent claims are also included for the following: (1) a device for pipetting volume of liquid (2) an analysis instrument for automatically analyzing samples.
