PETG, known as polyethylene terephthalate-1,4-cyclohexanedimethanol ester, is a transparent, non-crystallizing copolyester. It has taken its place in the manufacture of Erlenmeyer Shake Flasks by virtue of its outstanding toughness and high impact strength. Compared to modified polyacrylates, PETG has up to 3 to 10 times the impact strength, which makes it excellent at coping with the various stresses involved in cell culture. In addition, PETG offers a wide processing range, high mechanical strength and excellent flexibility, as well as higher transparency and gloss than PVC. These properties make PETG an ideal material for the production of high-quality Erlenmeyer Shake Flasks.

On the other hand, PC (polycarbonate) is also a high-performance plastic material. It is characterized by high strength and coefficient of elasticity, high impact strength, good fatigue resistance and good dimensional stability. Under high temperature conditions, the creep of PC is extremely small, maintaining good physical properties. At the same time, PC's high transparency and free coloring provide more possibilities for the design of Erlenmeyer Shake Flasks. The enhanced PC material has a UL temperature index of 120~140°C, ensuring the stable use of Erlenmeyer Shake Flasks in a wider temperature range.


To summarize, PETG and PC are two materials with their own characteristics, both of which can well meet the requirements of Erlenmeyer Shake Flasks for transparency, mechanical properties and chemical stability. When choosing Erlenmeyer Shake Flasks, research institutions can flexibly choose these two materials according to specific cell types and culture needs. Whether you are looking for higher toughness or wider temperature adaptability, both PETG and PC can provide satisfactory solutions to help cell culture research to be carried out efficiently.
