| titleOfInvention | N-methyl pyrrolidone purity measuring device |
| abstract | The utility model relates to a N-methyl pyrrolidone detects technical field, concretely relates to N-methyl pyrrolidone purity survey device, including a plurality of test tubes and a buret, still include base, pivot, test tube rolling disc, fixed cover, transmission shaft, screw-nut, float board, mounting panel, depression bar, piston, drive arrangement. The utility model discloses an initiative runner rotation on the drive arrangement, make its first gear revolve, the transmission is engaged with in turn with the initiative runner to the second gear, make the piston instil into the test solution in the buret into the buret, survey, because whole flow only needs the manual test solution titration operation to a plurality of test tubes that rotates of operation personnel can be accomplished, consequently, the efficiency of operation has been improved, intensity of labour can not produce basically, the test solution volume of instiling into at every turn simultaneously is in basic uniform state, the promotion of survey precision has been realized, moreover, the steam generator is simple in structure, and is easy and simple to handle, it is more convenient to maintain and change. |
