Procedure Application Note Temperature dependence of melt viscosity of candle 1.Scope The EMS viscometer is an instrument that can get sample information in a test tube in real timewith built-in camera. Examples of measuring the temperature dependence of the dynamic viscosity of candles usingan EMS viscometer that can be measured by sealing， sterilization and non-contact were shownbelow. 2.Precautions None. 3.Post-measurement procedure The sample container and the sample are discarded appropriately. 4. Apparatus EMS Viscometer Control Laptop PC 5.Reagents "Sample ：Japanese candle made of domestic beeswax， Candle made of paraffin wax 1) Enter the following conditions in measurement condition of the sequence mode of controlsoftware. Measurement mode ：Sequence mode Measurement temperature ：100→50℃(5℃ interval) Motor rotation speed ：1，000 rpm Measurement time I(1 second) Repeat count ：10 times Measurement interval ：5 seconds VWaiting time for temperature stability ：10 minutes 2) Place an aluminum spherical probe of o 2 mm and a the sample in the solid state to a container.cover with a cap and packing， set the sample container in the EMS Viscometer controlled tc100℃. 3) Click the measurement button after confirming that the sample has melted by the built-inCamera. 7. Example The measurement results about the temperature dependence of the melt viscosity ofcandle areshown in Figure 1 and Table 1，2. Japanese candle made of domestic beeswax is melted at 65℃ or more and the candle made ofparaffin wax is melted at 60℃ or more. The temperature dependence of the melt viscosity canbe measured. Moreover， the melt viscosity of Japanese candle made of domestic beeswax at each temperatureis able to obtain a high value compared with that of the candle made of the paraffin wax. Figure 1.

Summary Temperature dependence of the melt viscosity of the candle can be measured easily by putting acut solid candle in the sample container and heating it. Moreover， the difference of the melt temperature can be confirmed depending on the differenceof the material. 9.References 京都电子工业株式会社-可睦电子(上海)商贸有限公司电话： 电邮： kemu-kem@ com上海市徐汇区宜山路网址： http：//www.kem-china. com/ 都電子工業株式会社KYOTO ELECTRONICSMANUFACTURING CO.，LTD 蜡烛熔体在不同温度下黏度变化的研究 EMS粘度计是一种可以在试管内用内置摄像头实时获取样品信息的仪器。使用EMS粘度计测量蜡烛动态粘度随温度变化的例子，这种粘度计可以通过密封、灭菌和非接触式的测量。
