Tapping type sterile homogenizerIt is a commonly used instrument and equipment in laboratories for microbial detection sample preparation, mainly used for bacterial separation and homogenization treatment of food, drugs, cosmetics, and biological samples.

　　Tapping type sterile homogenizerWorking principle:

Homogenization mechanism:

Sample sealing and loading: Place the sample to be processed (such as meat, fruits and vegetables, sauce) together with sterile diluent (such as physiological saline, buffer solution) into a dedicated sterile homogenization bag, seal it, and place it in the stainless steel homogenization chamber of the equipment.

High frequency tapping effect: The tapping plate inside the chamber moves back and forth at a high frequency of 1000-3000 times per minute to gently tap the homogeneous bag, causing the sample to continuously collide, tear, and then break into small particles (usually 10-100 μ m in size) in the diluent, forming a uniform suspension.

Non cross contamination design: The sample is kept in a sealed homogeneous bag throughout the entire process, without direct contact with the equipment chamber or tapping plate, to avoid residual sample contamination of the next batch and prevent the leakage of harmful substances in the sample.

Aseptic assurance:

Aseptic contact material: The homogeneous chamber and tapping plate are made of 304 stainless steel, with a surface treated by electrolytic polishing, smooth and dead corners, and can withstand high temperature and high pressure sterilization or ultraviolet disinfection.

Sealing and isolation design: The homogeneous chamber door is equipped with a silicone sealing ring, which forms a closed space after closure to prevent external air pollutants from entering; Some models are equipped with a "negative pressure exhaust" function to further reduce pollution risks.
