Recently, when a customer was buying milk tea at a tea beauty store, he noticed a new tool he had never seen before in the shop assistant's hands. He was so surprised that he photographed the scene and posted it on social platforms. Unexpectedly, it attracted the attention and discussion of many netizens.

Judging from the picture, the clerk used a certain brand of 5ml pipetting gun. Most of this tool appears in the laboratory and is used to pipette small or trace amounts of liquid. Compared with containers such as measuring cups, pipetting guns measure liquids more accurately. Therefore, most of the onlookers were particularly shocked when they saw milk tea workers weighing raw materials and blending milk tea using professional tools.

At the same time, when some users saw this scene, they suddenly thought of the days when they were doing experiments with pipettes in college, and joked that college students majoring in biology will have another employment direction in the future, which is to go to a milk tea shop to use experimental equipment to make milk tea.

However, in addition to ridicule, netizens who had experience in operating pipette guns could not help but scream when they saw this scene, bluntly saying that the brand's practice of equipping stores with pipette guns was likely to pose food safety risks.

According to the popular science of Baidu Encyclopedia and laboratory staff, pipette guns are precision instruments used in laboratories. There are many precautions when using them. For example, they must not be placed horizontally or upside down after use. They need to be placed vertically on the pipette rack; used disposable gun heads need to be replaced in time to avoid contamination with other liquids.

However, in the pictures taken by netizens, only the clerk was seen using a pipette gun to measure the liquid. It was not seen whether the employee followed the usage requirements and placed the used pipette gun vertically on a special shelf or whether he replaced the gun in time. head.

In addition, some people pointed out that pipetting guns need to move gently and slowly when sucking liquids and use them strictly in accordance with operating specifications. Once the operation is careless, it is likely that the liquid will be sucked into the gun body. If it is not disassembled and cleaned in time, liquid will remain inside the pipette gun. Over time, bacteria may grow inside, which in turn creates a food safety and hygiene hazard during use.

Experienced experimenters said that although they had carried out many experiments with the pipette gun, they would inevitably make operational mistakes, causing the liquid to be sucked into the gun body. If milk tea shop assistants without relevant training use such experimental equipment, there is a greater chance that the operation will be irregular and the equipment will be contaminated during the process of making drinks.

To take 10,000 steps back, even if the store employees have certain experience and can use it strictly in accordance with the operating specifications of the pipette gun, users point out that it is still unknown whether the disposable tip equipped with the pipette gun is made of food-contact plastic, saying that "laboratory-level cleanliness and mouth cleanliness are completely two concepts."

Based on the above, a group of experimenters believe that using the laboratory's precision instruments when making milk tea is a bit overkill.
