POSITIVE TEMPERATURE COEFFICIENT HEATING OF LABORATORY DIAGNOSTIC INSTRUMENTS

A diagnostic device has a sample probe for receiving sample material from one or more containers, a sample line for delivering the sample material to one or more reaction containers, a reagent supply and reagent supply line for supplying reagent to the one or more reaction containers, an incubation ring for receiving the reaction containers and incubating a mixture of the sample material and the reagent for a period of time, and a heating system for heating one or more areas or components of the device. The heating system has one or more positive temperature coefficient heaters. 一种诊断设备具有：用于从一个或多个容器接收样本材料的样本探针；用于将所述样本材料输送到一个或多个反应容器的样本管线；用于向所述一个或多个反应容器供应试剂的试剂供应部和试剂供应管线；用于接收所述反应容器并且培育所述样本材料与所述试剂的混合物达到一段时间的培育环；以及用于加热所述设备的一个或多个区域或部件的加热系统。所述加热系统具有一个或多个正温度系数加热器。
