Scope of application of media bottles

Media bottle is a special packaging made of transparent polyester (PET/PETG) raw material with organic solvent added through injection stretch blow production process. In order to facilitate holding, the shape of the bottle is generally square, and the bottle body is marked with a scale. So, what are the main applications of media bottles?

1. Serum storage: Storage of serum is an important application of media bottles. Serum is a complex mixture formed by removing fibrinogen from plasma and should be stored at -5°C to -20°C. If stored at 4°C, it should not exceed one month. If one bottle cannot be used up at a time, it is recommended to aseptically aliquot the serum into an appropriate sterilized container and put it back into the freezer.

2. Medium storage and preparation: Medium is an artificially formulated nutrient for the growth and maintenance of microorganisms, plants and animal tissues, generally containing water, nitrogen sources, inorganic salts (including trace elements), carbon sources, Growth factors (vitamins, amino acids, bases, antibiotics, pigments, hormones and serum, etc.).

3. Buffer: When a certain amount of acid and alkali is added to some solutions, or a small amount of water is added to dilute, the solution has the effect of hindering the pH change of the solution, which is called buffering. Such a solution is called a buffer solution. The media bottle body has a scale, which is easy to observe the volume of the solution. The special square design is ergonomic and easy to grasp.

The above are the three application fields of the media bottle. The polyester raw material has good low temperature resistance and does not react to most acid and alkali solvents. These advantages also make the application range of the media bottle wider.

Material features of PETG media bottles

图片
  PETG media bottles   are a special packaging for storing various media, reagents, serum and other solutions, and it is also a product that scientific researchers have more contact with. The wide range of applications is mainly due to the superior properties of its materials. PETG is a transparent plastic that belongs to the non-crystalline copolyester. Serum needs to be stored in a low temperature environment. The use range of this material is -80°C to 60°C, which makes PETG media bottles fully meet the storage needs of serum. In addition, it has the following features: 1. High transparency, the light transmittance reaches 90%, which can reach the transparency of plexiglass; 2. It has stronger rigidity and hardness, excellent scratch resistance, impact resistance and toughness, which is close to or even exceeds that of polycarbonate (PC), and is suitable for injection molding, extrusion molding and extrusion blowing processing; 3. In terms of chemical resistance, oil resistance, weat

What are the common specifications of serum bottles

图片
  In biological laboratories, we often have to store various solutions and reagents. Thanks to the advantages of good performance, transparency, and temperature resistance, serum bottles have become "frequent visitors" in the laboratory. As a commonly used storage container, what are its common specifications?                      FuDau 60ml-Square-PETG-PET-Media-Bottles Common materials for serum bottles include PETG and PET, both of which have very good temperature resistance and transparency. In comparison, bottles made of PETG have more advantages in terms of barrier properties. If you want to pursue a better storage state of the solution, it is recommended to use a bottle made of PETG. There is a molded scale on the body of the bottle, we can clearly observe the capacity and state of the solution. The common specifications of this kind of container include 5ml/10ml/30ml/60ml/125ml/250ml/500ml/1000ml, etc., which are mostly used to store serum, culture medium, buffer, dis

Cell factory requirements for production raw materials

图片
Cell factories   are mainly used for large-scale cell culture. Cells have high requirements on the environment, such as temperature, humidity, osmotic pressure, pH value, etc. Therefore, this kind of   cell   consumables also has high requirements on raw materials. The first is transparency. In the process of cell culture, it is necessary to grasp the growth state of the cells at any time, and make corresponding adjustments according to the cell proliferation. Therefore, the raw materials of the cell factory must meet the requirements of transparency, so that it is convenient for researchers to observe the growth of cells. The second is the compatibility of materials. The raw materials of this consumable generally meet the requirements of USP Class VI medical polymer materials. Medical polymer materials refer to polymer materials used to manufacture human internal organs, external organs, pharmaceutical dosage forms and medical devices, and their sources include natural biopolymer mate
