Problems solved by technology

At present, the determination of the softening point of the plaster is generally heated by an electric furnace with adjustable power. This method cannot be accurately quantified for the determination of the softening point of the plaster, and cannot meet the requirements of the Pharmacopoeia.
Therefore up to the present, also there is not a kind of better method to accurately measure the instrument of plaster softening point

Embodiment Construction

[0008] Below in conjunction with accompanying drawing and through specific working process, the present invention is further described: each component is assembled according to shown accompanying drawing. Add the degassed water into the beaker 13 at room temperature, operate the buttons on the front panel 2 of the instrument, heat the water bath, adjust the on and off of the solid state relay 5 so that the water in the water bath reaches 37±1°C, and the water bath will maintain this temperature , the fan 6 discharges the excess heat in the casing to ensure that the control circuit board 14 works normally. Now put two sample rings 17, including plaster samples 19, into two positioning holes of the upper support plate 15 respectively, then put two steel ball locators 18 on the two sample rings 17 respectively, and then Put the steel ball 20 into the bottom of the beaker 13, and the instrument starts timing. During this process, the temperature sensor-7 will automatically adjust ...

Abstract

An analyzer of plaster softening point is prepared as setting beaker positioning ring at center of heating plate being set between its top cover and bottom cover, fixing said bottom cover on support frame through support column, setting fan in box and fixing it on box base through bolts. It is featured as using control circuit to control on and off of solid relay according to water bath temperature collected by temperature transducer, controlling water bath temperature by controlling the heating wire for satisfying requirement of each stage in analyzing course.

Description

technical field [0001] The invention relates to a drug testing instrument, in particular to an instrument for measuring the softening point of plasters. technical background [0002] The softening point of the plaster is an important indicator of the degree of softness and hardness of the plaster. In recent years, my country's pharmacopoeia has been further improved, and the determination of the softening point of plasters has been proposed. At present, the determination of the softening point of the plaster is generally heated by an electric furnace with adjustable power. This method cannot achieve accurate and quantitative determination of the softening point of the plaster, and cannot meet the requirements of the Pharmacopoeia. Therefore up to now, also there is not a kind of better method to accurately measure the instrument of plaster softening point. Proposing of the present invention can make this problem be solved satisfactorily. ...
