With the continuous development of biotechnology, high-efficiency erlenmeyer shake flasks are playing an increasingly important role in cell culture. Cell culture requires a specific environment, and the requirements for cell consumables are relatively high. So which material is used for the high-efficiency erlenmeyer shake flask and what are its characteristics?

The material used for high-efficiency erlenmeyer shake flasks is mostly PETG, which is a transparent amorphous copolyester. Its products have high transparency. Traditional extrusion, injection, blow, and blister molding methods can be used. It is used in the market of sheet material, high-performance shrink film, bottle and profiled materials, and has the following characteristics:

1. Thermoforming performance

PETG sheets are easy to produce products with complex shapes and large stretch ratios. Moreover, unlike PC board and impact-modified acrylic, this board does not need to be pre-dried before thermoforming. Compared with PC board or acrylic, its molding cycle is short, the temperature is low, and the yield is higher.

2. Toughness

The extruded sheet of PETG sheet is usually 15 to 20 times tougher than general acrylic and 5 to 10 times tougher than impact modified acrylic. PETG sheet has sufficient bearing capacity during processing, transportation and use, which helps prevent cracking.

3. Weather resistance

PETG sheet provides excellent weather resistance. It can maintain the toughness of the product and prevent yellowing. It contains ultraviolet absorbers, which can be co-extruded into a protective layer to protect the board from the harmful effects of ultraviolet rays.

4. Easy to process

PETG sheet can be sawed, die-cut, drilled, punched, cut, riveted, milled and cold-formed without breaking. Slight scratches on the surface can be eliminated with a hot air gun. Solvent bonding is also a normal operation. It is easier to process than general acrylic, impact modified acrylic or PC board, and can be processed for flocking, electroplating, static electricity and other processing.

5. Chemical resistance

PETG sheet can withstand a variety of chemicals and common cleaning agents.

6. Economic and environmental protection

PETG sheet substrates are all environmentally friendly materials, which meet the requirements of food contact management. It is cheaper than a PC board, and it is more durable than a PC board.

The above are the material characteristics of high-efficiency erlenmeyer shake flasks. These characteristics of PETG meet the requirements of cell culture technology for consumables, and it is a high-quality polymer material.

The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.

The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.

In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.

Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.

NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.

In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
