In use of sedimentation method to measure the clump count, the method, which can not be used to get directly the bacteria number of the unit volume, does not meet the requirements of "GMP" standard in our country.

According to the principle of grain bombardment, we have developed JYQ portable biological sampler , which can directly measure the bacteria number within 1 m3 air volume to cooperate with the execution of "GMP" standard effectively.

The structure of the product is reasonable and its technical performance ranks the leading position in our country, in which the sampling quantity is up to 50L/min, the comprehensive level of instruments (JYQ-II; JYQ-III) reaches the level of external level of the same products in 1980s.

Welcome customers to choose JYQ portable biological sampler，which will lay good effect on the quality of food and medicines. It is the necessity of medicine appliance production enterprises.
