PETG serum bottles can be used for the storage of balanced salt solutions
There are many types of cell culture consumables, PETG serum bottle is one of them, it can be used not only to store serum, but also to store balanced salt solution (BSS).
Balanced salt solution is a salt solution with an electrolyte content similar to that in plasma. The main components are inorganic salts and glucose. Its function is to maintain cell osmotic pressure balance, maintain pH stability and provide simple nutrition. It is mainly used for rinsing cells and preparing other reagents.
There are two commonly used balanced salt solutions, D-Hank's and Hank's. The main difference is that the former does not contain Ca2+ and Mg2+, so D-Hank's is often used to prepare pancreatic enzyme solutions. Because Ca2+ and Mg2+ are important components of cell membranes and participate in cell adhesion and other functions, the use of BSS without Ca2+ and Mg2+ can avoid cell clumping. In addition, Hanks solution and Earle solution are commonly used BSS basic solutions. The former has a weak buffer capacity and is suitable for closed culture; the latter has a strong buffer capacity and is suitable for 5% CO2 culture conditions.
The serum bottle is made of transparent PET raw material, which has high transparency and low temperature resistance, and can resist the erosion of most acids, alkalis and other solvents, and is a good packaging material. There is a molded scale on the bottle body of the package, which is convenient to observe the volume of the solution. For easy grip, the packaging has a square bottle design, which is ergonomic and saves a certain amount of space.
