　　2.Able to handle various issues in a timely and fast manner,relieving customers of any worries they may have;

　　3.Complete spare parts to solve the problem of long lead times when ordering spare parts;

　　4.Keep up with industry standards updates and provide textile testing instruments that meet the new standards in a timely manner.

　　G287 Dry Microbial Penetration Performance Tester is mainly used to measure the bacterial penetration performance on dry particles within a large or small range of human dandruff material impedance.

　　Compliant with standards:

　　ISO 22612 Test method for dry microbial penetration of infectious agent protective clothing

　　YY/T 0506.5-2009 Surgical sheets,surgical gowns,and clean clothing for patients,medical staff,and instruments Part 5:Test method for dry microbial penetration

　　Operation:

　　1.Firstly,prepare the accessories and test samples;

　　2.Turn on the power switch of the instrument and enter the LCD screen display interface;

　　3.Set parameters such as vibration frequency and operating time;

　　4.Turn on the lighting and sterilization for sterilization treatment;

　　5.Cut sterile samples into dimensions of 20 centimeters by 20 centimeters and place them in the test container;

　　6.Cover the sample with a lid and push it down with a piston to control the degree of relaxation of the sample;

　　7.Add about 0.5 grams of bacterial sliding powder;

　　8.Insert the culture dish into the narrow opening at the bottom of the container;

　　9.Use adhesive tape to seal the top and sides of the narrow opening;

　　10.Fill 5 containers with talcum powder,and do not add talcum powder to the 6th container;

　　11.Place 6 testers into the instrument testing platform;

　　12.Click on[Start]on the screen;

　　13.Run at a frequency of 20800 per minute for 30 minutes;

　　14.Automatically stop at the set time and remove the container;

　　15.Tear off the tape,remove the culture dish,and incubate it in a 35 degree Celsius environment for 24 hours.Count the bacterial colonies in the row,and the effective sample should be a reference dish with a reading of 0.Otherwise,it indicates external contamination,and the experiment should be terminated;

　　16.Repeat the above experimental steps and test at least two sets.Calculate the average of 10 valid results as the final result.
