根据药典规定,须检验成品熔点,由于长年在仪表计量室负责维修化验仪器,对WRS-1型数字熔点仪的常见故障总结出如下一些维修方法。1.插入毛细管后电流表不归零该设备插入毛细管后电流表应为零,因为毛细管中的药品挡住了光路。药品熔解后,光透过玻璃毛细管到达光电池,光电池感光输
According to the Pharmacopoeia, to test the melting point of the finished product, as a result of many years in the instrument measuring room responsible for the maintenance of laboratory equipment, WRS-1 type digital melting point common faults summarized as follows some maintenance methods. 1. The ammeter does not return to zero after the capillary is inserted The ammeter should be zero after the device is inserted into the capillary because the drug in the capillary blocks the light path. After the drug is melted, the light reaches the photocell through the glass capillaries, and the photocells lose light
