PETG square media bottle is a plastic bottle made of polymer material by injection, stretch and blow process. Different from ordinary round bottles, this container adopts a square bottle design. What is the principle based on? What are the advantages of such a design?
1. Easy to hold: PETG square media bottle is mainly used to store various medium, serum and other solutions, which are essential nutrients for cell growth. When culturing cells, it is necessary to observe the growth state of the cells at any time, and decide whether to add various media to ensure the nutrients required for cell growth according to the growth of the cells and the consumption of nutrients. During this process, the medium is frequently taken, and the square bottle design conforms to the ergonomic design, which is convenient for operators to grasp.
2. High space utilization: The square design has a larger storage capacity than the round shape. In addition, due to the particularity of the medium components, if long-term storage needs to be frozen at -20°C - 70°C, the storage cost of the freezer is higher than that of the freezer. The room temperature storage cost needs to be done. The square shape saves more space than the round shape and can store more products.
In summary, the square design of the PETG square media bottle is convenient for the operator to grasp on the one hand, and storage space is saved on the other hand, which are the two main reasons for choosing the square bottle design. In addition, this bottle is also used for cell lysate and trypan blue solution.
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.
