How to reasonably control the breeding density

In general, if the density of life is too high or there are many disturbances, it is easy to kill each other and die. However, under the rearing conditions, with the improvement of living environment and feeding conditions, such as providing enough fresh feed and water, no increase in disturbing its life, even if the breeding density is relatively large, it will have little impact on their lives. In particular, because the cockroaches produced by the same mother have lived together since childhood, they grow up to dozens of rolls together, and they can cohabit with them. Therefore, providing enough fresh feed and water to maintain a quiet environment is a prerequisite for artificial breeding. Unless it is necessary to cultivate seedlings, as far as possible, avoid mixing the pups produced in different breeding ponds.

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.
