A method for checking the quality of thermal coupling between a measuring cell and a thermostatted element of an analyzer, where the measuring cell can be exchangeably inserted into an analyzer to measure at least one parameter of a sample, and is provided with at least one sensor element in a measuring channel.

Method for monitoring the thermal coupling of a measuring cell

The invention relates to a sample entry device for delivering medical samples, preferably blood samples, from diverse sample containers to an analyzer, wherein sample transfer between sample intake and measuring cells of the analyzer taking place via gas-tight sample lines. According to the invention a fixed intake needle is provided at the entry side of the analyzer, which includes an elastic intake element that is axially slideable on the intake needle and has a conical intake opening. In addition, a holding element is provided, which is axially slideable parallel to the intake needle and can be shifted relative to the intake element. In a first position the holding element exposes the intake element and in a second position places a conical opening above the intake element to accommodate a syringe.
