Detailed Description

The present invention will be further explained below.

As shown in fig. 1, the utility model provides a laboratory batcher, including end cap 1, drawing liquid piston 2, scale 3, go up spacing I4, cylindricality valve 5, lower spacing I6, glass fluid-discharge tube 7, slider locating lever 8, metal location slider 9, slider location jackscrew 10, metal top end cap 11, glass overcoat 12, bleeder vent 13, glass post check valve 14, upper spacing II 15, lower spacing II 16, glass grinds mouthful joint 17, feed liquor pipe 18, glass cover 19.

The bottom of the end cap 1 is provided with a liquid pumping piston 2 and a slide block positioning rod 8; a metal positioning slide block 9 is connected on the slide block positioning rod 8 in series, a slide block positioning jackscrew 10 is screwed on the metal positioning slide block 9, and a metal top end cap 11 is fixed on the lower part of the slide block positioning rod 8. Is arranged on the glass outer sleeve 12. The upper part of the glass outer sleeve 12 is internally inserted with a liquid pumping piston 2. The side surface of the glass outer sleeve 12 is provided with a glass liquid discharge pipe 7, an upper limit I4 and a lower limit I6 are arranged inside the glass liquid discharge pipe 7, the cylindrical valve 5 moves between the upper limit I4 and the lower limit I6, the process is in a sealed state when the lower limit I6 is in contact with the cylindrical valve 5, and the process is in an unsealed state when the upper limit I4 is in contact with the cylindrical valve 5. A liquid inlet pipe 18 and a glass cover 19 are arranged below the glass outer sleeve 12, the glass cover 19 covers the upper end of the outer part of the liquid inlet pipe 18, and the lower end of the liquid inlet pipe 18 is inserted into the glass bottle 20; the glass cover 19 is inserted on the glass ground joint 17 of the glass bottle 20.
