The tester for preventing the penetration of dry microorganisms is specialized in measuring the resistance of materials to the penetration of bacteria on dry particles within the range of human dandruff size.
Dry Penetration Tester Suppliers for preventing penetration of dry microorganisms
The instrument is completed in strict accordance with the standard drawings, which fully meets and can realize the test content required by the standard.
What are the main components of the instrument for dry penetration tester?
1. Pneumatic ball oscillator: the external air source passes through the pneumatic ball oscillator. After corresponding adjustment and correction, the vibration frequency is kept at the target frequency. It can generate 20,800 vibrations per minute with a force of 650n n.
2. Compressed air flowmeter: it is mainly used to measure the air flow with a frequency of 20800347Hz and sub-vibration every minute.
3. Test containers: The instrument has 6 stainless steel test containers with metal pistons at the top. The metal piston can be inserted 10 mm below th e cover through the central hole on the cover, and the specimen will not come loose after insertion. At the same time, the attachment at the bottom of each container has a slit for inserting the culture dish.
4. Marble board: Marble with an area of 400mm*400mm and a thickness of 10mm is used as the operating platform of the whole instrument.
5. Fixing plate: a stainless steel plate with 6 holes, which is fixed on the stone plate with a clamp for fixing and installing the test container.
6. Rubber supports: with 4 rubber supports, it is used to adjust the level, fix the position of the instrument and prevent it from moving.
A large number of examples show that bacteria can penetrate the shielding material through dry organic or inorganic particles (such as dander or bacter ia carried on clean clothes), while bacteria-carrying particles can penetrate into the packaging material during storage. The dry microbial penetration tester can be used to measur e the permeability of bacteria to dry particles within the size range of human dandruff.
