Due to weak demand and abundant supply of methanol, methanol prices in the Asian market were weak during the period. China's domestic price has dropped to 330 US dollars (ton price, the same below), and the market price in South China is low.

Ethylene glycol During the current Asian ethylene glycol (MEG) spot price rose 28 to 35 US dollars to 1053 to 1065 US dollars (CFR, China's main port), reflecting the current bargaining power and transaction price levels. Most of the quotes that appear in the market are those that have arrived or are about to arrive. Vendors are reluctant to sell far-reaching products quickly because the overall prospects for 2011 are optimistic and buyers are actively asking for a price.

Demand from the downstream unsaturated polyester resin and polyurethane industry remained weak during the off-season at the end of the year. Supplies will increase in the first quarter of next year and additional ocean-going cargo from the Middle East and the United States will arrive. Speculative traders continued to hoard stocks as they are expected to be optimistic.

A vendor stated that Southeast Asian prices may exceed China's price by 30 US dollars, but there is no transaction to support this price. In the Chinese market, the low price of downstream dioctyl phthalate stabilized the octanol price at the level of $1,795 (CFR, China), and the domestic stable octanol price was also affected by the price of raw material propylene. As market calm buyers lowered their purchase intention prices, supply remained tight. China's domestic prices fell by 200 yuan to 14,300 yuan, or 1,728 US dollars. South Korea's Hanwha Chemical Company quoted a price of 1,850 US dollars (CFR, China) for a group of 1,000 tons of goods, but did not close a deal before the close.

The advantage of the plastic centrifuge tube is that it is transparent or translucent, its hardness is small, and the gradient can be taken out by the puncture method. The disadvantage is that it is easy to deform, has poor corrosion resistance to organic solvents, and has a short service life.
Plastic Centrifuge Tubes have caps, which are used to prevent sample leakage, especially when used for radioactive or highly corrosive samples. It is very important to prevent sample leakage; the tube cap also has a function to prevent sample volatilization. And support the centrifuge tube to prevent deformation of the centrifuge tube. When choosing this point, you should also pay attention to check whether the tube cover is tight, and whether it can be tightly covered during the test, so as to achieve the inversion without leakage;
