Main Functions of Square Media Bottle
Square Media Bottle was originally designed to address the need for liquid substance storage in biology experiments. Specifically, they are mainly used to store the following solvents:
1. Serum and culture medium
Serum, as one of the basic components in cell culture, usually contains a variety of growth factors and binding proteins, which can provide nutrients for cells and promote cell growth and division. In order to maintain the stability of serum, it usually needs to be stored at low temperature. Square Media Bottle can effectively store serum at low temperatures ranging from -20°C to -70°C to ensure its long-term effectiveness.
Culture medium is also the basic material for cell culture, containing carbohydrates, nitrogen sources, vitamins and other elements to maintain normal cell growth and reproduction. When storing culture medium, it is usually required to protect it from light and keep it within the temperature range of 2℃ to 8℃.
2. Storage of various biological reagents
In addition to serum and culture medium, Square Media Bottle is also widely used for storing various biological reagents, such as antibiotics, buffers, dissociation reagents, staining solutions and so on. These reagents have different requirements on the environment when storing, for example, some reagents need to be stored at a low temperature of -20℃, while some can be stored at room temperature. The versatility and temperature resistance of Square Media Bottle make it an ideal container for storing these reagents.
Material analysis: choice of PET vs.
The material of a Square Media Bottle has a significant impact on its performance and usage scenarios. There are two main materials commonly available on the market: PET and PETG, which have their own characteristics and are suitable for different experimental needs.
PET material: it has excellent low temperature resistance and can keep its mechanical properties stable at -70℃, which is suitable for the low temperature preservation of serum and other liquids. The impact strength is 3 to 5 times higher than other film materials and has good folding resistance, ensuring that it will not be easily damaged during long-term use.PET material has high transparency and good gloss, which helps to observe the state and changes of the liquid inside the bottle and is suitable for experimental occasions that require clear observation.
PET has strong oil resistance, fat resistance and resistance to most dilute acids and alkalis, and can effectively resist the erosion of most chemical substances.
PETG: PETG has a transparency of up to 90%, which is almost comparable to glass, making the observation of the state of serum or culture medium clearer.PETG's stiffness and hardness are also better than PET, with excellent scratch resistance and impact resistance, and stronger toughness, which is able to withstand higher intensity of external forces. Compared with PET, PETG has a better performance in chemical resistance, oil resistance and weather resistance, which makes it especially suitable for storing reagents that require high chemical stability, such as antibiotics and buffers. Due to its non-toxic and odorless characteristics, PETG is widely used in the production of food packaging, pharmaceutical packaging and medical devices to ensure the hygiene and safety of the containers.PETG is an environmentally friendly material, which can be easily recycled after disuse, and does not release hazardous substances when incinerated, which has less impact on the environment.
Application and Selection Suggestions for Square Media Bottle
In the laboratory, choosing the right material for Square Media Bottle not only ensures the stability of liquid storage, but also improves the safety and accuracy of experiments. For experiments that require higher transparency and impact resistance, especially when storing precision reagents or cell culture solutions, it is recommended to choose Square Media Bottle made of PETG. For general storage needs, Square Media Bottle made of PET can also meet the requirements of low temperature storage and liquid volume measurement.
All in all, Square Media Bottle, as a common storage container in the laboratory, has become an indispensable working partner for researchers by virtue of its high transparency, good low-temperature resistance and easy-to-operate scale design. Whether it is for storing serum, culture media or reagents, they play an important role. By understanding the characteristics of different materials and how to choose the right Square Media Bottle, you can help make your lab work more efficient and precise, and ensure the reliability and reproducibility of your experimental results.
