今日出 厂产品展示及部分报价


A) use electric heating plate
电热板(Hot Plate)是以电 流的热效应所产生的热来使物质温度升高的装置.许多电 热板附有转动的磁铁使磁搅拌子(stirrer)旋转,以使溶液搅拌均匀,因此亦 称为电磁加热搅拌器.
Electric heating plate (Hot Plate) is a device of heat to make the temperature of the material in the heating effect of the current generated by the increased. Many electric heating plate with rotating magnet the magnetic stirrer (stirrer) rotation, so that the solution stirring, therefore also known as electromagnetic stirrer.
电热板 的表面通常为陶瓷平板,适宜加热玻璃器皿.加热时,亦可用 磁搅拌子进行搅拌,以加速反应的进行.
The surface of the electrothermal board usually ceramic plate, suitable for heating glassware. Heating, can also be used magnetic stirrer to stir, to accelerate the reaction.
(二) 操作方法
(two) operation method
1. 电热板使用时,先将欲 加热的物体放在板面上.
1 electric heating plate when in use, first to be heated object on the floor.
2. 将温度 调节钮与搅拌速率调节钮同时先调至零.
2 temperature control and stirring speed adjusting button at the same time, first to zero.
3. 打开电源开关.
3 turn on the power switch.
4. 旋转温度调节钮,先置於低温,再视所需温度,慢慢升高.即由LOW,MODERATE至HIGH.或由1,2…..慢慢增加.
The 4 rotation control knob, first at low temperature, and then the required temperature, slowly rise. From LOW, MODERATE to HIGH. or from 1,2… . slowly increased.
5. 旋转搅拌速率调节钮.
The 5 rotating stirring speed adjusting knob.
6. 使用完毕,将温度调节钮,搅拌速 率调节钮及电源开关切掉.
6 after use, the temperature regulating knob, stirring speed adjusting knob and a power switch off.
(三) 注意事项
(note three)
1. 电热板表面为陶瓷板,加热时 外观上并无没有明显的变化,故取拿 时应先以手靠近板面以探知板面是否温热,若有温 热状态应小心操作.
1 of the surface of electric heating plate is a ceramic plate, heating the appearance does not have no obvious change, so take should first hand close to the surface in order to ascertain whether the warm surface, if there should be careful about the operation temperature.
2. 电热板在使用时,板面若 溅到化学品应立即清理乾净,否则加 热后的物质碳化后极难清除,亦会妨 碍加热的均匀性.
2 electric heating plate when in use, the surface splashes into the chemicals should be cleaned immediately, otherwise the matter carbonizing heating after very difficult to remove, will also hinder the heating uniformity.
3. 通常只 有平底的容器才用电热板加热.
3 is usually only a container with electric heating plate.
4. 磁搅拌 子乃是一颗以特氟纶(PTFE)被覆的柱状磁铁.
The 4 magnetic stirrer is a Teflon (PTFE) columnar magnet coated.
5. 电源关掉后,板面仍然很烫,需要小心,避免烫伤.
5 turn off the power, is still very hot, be careful, avoid scalding.
