In the first half of this year, the Tianjin Entry-Exit Inspection and Quarantine Bureau intercepted eight batches of unwasteped and unbroken plastic containers, with a total weight of 267 tons and a value of $81,501. The Inspection and Quarantine Bureau has already returned all wastes in accordance with relevant regulations. According to the staff, the problem of the 8 batches of imported plastic waste is due to the unwashed and unbroken plastic containers that do not meet the environmental protection standards in China. In order to prevent some unscrupulous people from using unbroken plastic containers, especially plastic containers filled with beverages to shoddy, thereby harming the interests of consumers, our country stipulates that unopened plastic containers are prohibited from entering China. It is understood that waste plastic is the main type of imported wasteable raw materials. With the rapid development of domestic industries, the supply of plastic raw materials is also increasingly in short supply. The cost of imported waste plastics is low, and the profits of reuse are high. In recent years, the import volume has been presented. Rising trend. In the first half of this year, Tianjin Port imported 3,315 batches of waste plastics, with a total weight of 166,112 tons, valued at 52,083,055 USD, which was an increase of 91%, 94%, 101%, and 173% respectively over the same period of last year.
A pipette, also known as a pipette gun, is a device used to quantitatively transfer liquids. When conducting research in analytical testing, a small or trace amount of liquid is generally removed with a pipette. Pipettes can be divided into gas piston pipettes (Air-displacement pipette) and external piston pipettes (Positive-displacement pipette) according to the principle. Gas piston pipettes are mainly used for standard pipetting, and external piston pipettes are mainly used to handle special liquids such as volatile, corrosive and viscous. Many people ignore the correct use of pipettes and some of the details.

At present, in China's plastics market, labels for waste caps, waste bottles, and even bottles are sold at a certain price. If the plastic container is broken and then enter the country, the selling price will be much lower than the price for single-sale. In addition, labor costs for cleaning and crushing in foreign countries are relatively high. Therefore, many companies clearly know that these waste plastics do not conform to the national environmental protection regulations, but they are still imported with luck.
