1.High permeability: allows the exchange of oxygen and carbon dioxide, maintaining normal respiration of the culture.
2.Waterproof and moisture-proof: effectively prevent water evaporation and external moisture from entering, and maintain the humidity of the culture environment.
3.Anti-pollution: effectively block the invasion of bacteria, fungi and other microorganisms to reduce the risk of pollution.
4.High transparency: easy to observe the growth of the culture.
5.High temperature resistance: can withstand high temperature sterilization (such as high pressure steam sterilization).
