Our medicinal synthetic polyisoprene gasket for injection does not contain any substances that can easily produce pyrogen. We now use a unique technique to add cytotoxicity to the routine test of butyl rubber stoppers such as pyrogen, hemolysis, acute systemic toxicity test and so on. Systemic injection test and intradermal stimulation test have been used abroad for many years.Our good puncture resistance ensures the minimum rate of chip drop during the puncture process and our good self-sealing performance can guarantee no leakage during using process in hospital.Also,good retention of puncture device ensures that there is no needle slider and needle drop in the process of hospital use.
