Several conditions necessary for PETG media bottles

As an essential nutrient for cell growth, serum has a good protective effect on cells in culture, and the quality of serum directly affects the growth state of cells. PETG media bottle is a special container for storing serum, it must meet some necessary conditions to ensure the stability and safety of serum during storage.

Low temperature resistance: The storage of serum is different from ordinary items, and generally needs to be stored in an environment of -5°C to -20°C. If stored at 4°C, try not to exceed one month. This requires that the media bottle must have good low temperature resistance to meet the low temperature storage requirements of serum.

PETG Media Bottles

Transparency: The quality of the serum, which we can initially discern by its appearance. A good serum should be transparent and clear, earthy yellow or brownish yellow, with no or very little precipitation, and relatively viscous. If the serum is found to be turbid, opaque, and contains many precipitates, it indicates that the serum is contaminated or the protein in the serum is denatured. In order to grasp the status of the serum in time, the body of the media bottle must have a good transparency, which is convenient for the experimenters to observe.

Sealing: Good sealing of the container is the prerequisite for good storage of serum. If the lid does not fit well with the mouth of the bottle, it will easily lead to the invasion of external bacteria and affect the quality of the serum.

To sum up, low temperature resistance, transparency, and tightness are the basic conditions necessary for PETG media bottles. In addition, in order to facilitate the observation of serum capacity, there are generally molded scales on the body of the bottle; in order to facilitate grasping, this container Most of them use square bottle design.
