    • A stirring hot plate (20) having an electrical heating element (30) embedded in a generally horizontal plate (26) for supporting a vessel containing a substance to be selectively heated and stirred. The stirring hot plate (20) has a high temperature enclosure (84) mounted to the bottom of the plate (26) that receives the ends (32, 33) of the electrical heating element (30). A stirring device drive (64) and control (68) are mounted in a low temperature enclosure (86). A tubular conduit (96) has one end (107) connected to the low temperature enclosure (86), and an opposite end (98) connected to the high temperature enclosures (84). The tubular conduit (96) has an internal passage (97) for receiving and carrying wires (76, 80, 83) between the high and the low temperature enclosures (84, 86). The tubular conduit (96) is made of a material having a low thermal conductivity to maintain the one end (107) of the conduit (96) at a temperature substantially lower than the opposite end (98) having a temperature approximately equal to the temperature of the plate (26).
    • 一种搅拌热板(20),其具有嵌入大致水平板(26)中的电加热元件(30),用于支撑含有要选择性地加热和搅拌的物质的容器。 搅拌热板(20)具有安装在板(26)的底部的高温外壳(84),其接收电加热元件(30)的端部(32,33)。 搅拌装置驱动器(64)和控制装置(68)安装在低温外壳(86)中。 管状导管(96)具有连接到低温外壳(86)的一端(107)和连接到高温外壳(84)的相对端(98)。 管状导管(96)具有内部通道(97),用于接收和承载高温和低温外壳(84,86)之间的导线(76,80,83)。 管状导管(96)由具有低导热性的材料制成,以将导管(96)的一端(107)保持在温度基本上低于相对端(98)的温度,其温度近似等于温度 的板(26)。
