| titleOfInvention | A manual stirring device |
| abstract | The utility model discloses a manual stirring device, which comprises a hand-held part, a hollow glass tube is fixedly connected to the lower surface of the hand-held part, and a stirring plug with holes is fixedly connected to the lower surface of the hollow glass tube; The upper surface of the plug is provided with holes. The utility model can reduce unnecessary air bubbles entering the liquid to be measured during the five-day biochemical oxygen demand measurement process by designing a hole and a stirring plug with a hole, and can make the liquid in the step of diluting the solution quickly and fully mixed uniformly, Therefore, the measurement results are more accurate. By designing the hollow glass tube, the structure is simple, the cost is low, and it is suitable for the five-day biochemical oxygen demand pretreatment process of environmental water. |
