Description
Technical Field
The utility model relates to a novel pipette and supporting multi-functional auxiliary device convenient to volume get medicine, a novel liquid-transfering device convenient to volume get medicine promptly belongs to indoor chemistry experimental facilities technical field, is particularly useful for the experiment that the accurate volume of pipette need be used to the indoor experiment and the medicine is got.
Background
Since the three gorges reservoir impoundment, the branch reservoir bay generally has the phenomenon of water eutrophication, and the phenomenon of water bloom also generally occurs in each branch. The outbreak of the water bloom is the result of the combined action of nutrient elements such as N, P and environmental factors such as temperature, flow rate and the like. In order to explore the influence of the contents of various nutrient salts of rivers on the rivers, the contents of the various nutrient salts in the water body need to be measured, and before measuring nutrient substances in the water body, the concentration of medicines for measuring various nutrient indexes in experiments needs to be checked to ensure the correctness of medicine preparation. Therefore, before carrying out the experiment, a pipette is used to measure different amounts of standard nutrient salt, and the drug prepared in the experiment is used to monitor the content of the standard nutrient salt.
However, when the pipette is used for measuring the standard nutrient salt index, the caliber of the pipette is small, the standard nutrient salt is not easy to be sucked into the pipette due to the large caliber of the balloon when the balloon is used for sucking the medicine, and in addition, the standard nutrient salt sucked into the pipette is often larger than the amount required by the experiment, so that the amount of the standard nutrient salt in the pipette is controlled by slowly releasing the finger at one end of the pipette, the operation of measuring the amount of the standard nutrient salt is performed, the medicine in the pipette is usually quickly dropped out due to the fast release of the finger, the amount of the nutrient salt in the pipette is smaller than the amount required by the experiment, the pipette is required to be used again for measuring, the experiment time is prolonged, or the medicine in the pipette is slowly dropped due to the slow release of the finger, the contact time between the medicine and the air is prolonged, and some substances in the air are in contact with the medicine for, cause the failure of experiment easily, the easy medicine contact of getting with using the pipette volume of finger in the experimentation easily pollutes the medicine, more seriously can cause the injury to the human body, often can not make the pipette keep perpendicular when using the pipette volume to get the medicine in addition, and this just makes the interior medicine slope of pipette, and the reading produces the error when getting the medicine, causes the experiment failure.
