Operation steps:

First: prepare the accessories and test samples;

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

Set the vibration frequency and running time and other parameters;

Turn on the lighting and sterilization and carry out thea sterilization;

Cut the sterile test into a size of 20 cm by 20 cm. Put the sample into the test container;

Close the lid and push the sample with the plunger to control the degree of relaxation of the sample;

Add approximately 0.5 grams of contaminated slip powder;

Insert the Petri dish into the narrow opening at the bottom of the container;

br />

Seal the top and side openings with tape;

Put 5 containers with slippery powder and do not add any slippery powder to the sixth container ;

Put 6 testers into the instrument to test the platform;

Click [Start] on the screen;

Run at a frequency of 20,800 per minute for 30 minutes;

It will automatically stop when the set time is reached and remove the container;

Remove the adhesive tapeIf, remove the petri dish and incubate it in a 35 degree Celsius environment for 24 hours. and count the colonies. , the effective sample should have a reading of 0 in the control box, otherwise it means there is external contamination and the test should be stopped;

Repeat the steps of test above, test at least two groups, and calculate the average of 10 valid results, as the final result.
