| 摘要 |
A quantitative pipette includes an air bag, an air-guiding tube, a liquid-storing capsule and a quantitative capillary. Said air bag, said air-guiding tube and said liquid-storing capsule are all made of transparent polymer material, and connected sequentially to be communicated through internal holes. Said quantitative capillary is made of transparent polymer material or glass material. The upper end of the quantitative capillary is inserted into the liquid-storing capsule and close to the air-guiding tube, and the lower end of the quantitative capillary projects out the liquid-storing capsule. Volume of the quantitative capillary is selected based on the volume of the liquid to be pipetted. |
