Fiber glass syringes are known for their good chemical stability and high-temperature resistance. Fiber glass, mainly composed of silicon dioxide, aluminum oxide, etc., has high tensile strength and good electrical insulation.

The syringe made of this material can maintain its strength at temperatures up to 300 ℃, making it good at applications that require high-temperature sterilization. In addition, fiber glass syringes have good chemical stability and resistance to many chemical drugs, making them more reliable in handling corrosive drugs, which is particularly important for sensitive biological agents.

In contrast, nylon syringes are favored for their lightweight and cost-effectiveness. Nylon is a synthetic plastic with good toughness and wear resistance. It performs well in handling drugs containing water, as nylon has a certain affinity for water, making it more effective in filtering and injecting water-based drugs.

However, it may not be as chemically compatible as fiber glass syringes, especially when it comes to certain solvents.

For example, according to the chemical compatibility list, nylon film exhibits incompatibility or partial compatibility when in contact with solvents such as acetone, acetonitrile, and benzene. This means that it may not be suitable for the storage and transfer of these solvents, as they may react with nylon materials, causing material degradation or drug contamination.
