The original state of microbial samples may be block, paste, powder, etc., which must be made into fine liquid samples in order to facilitate the analysis and inoculation of microorganisms. The Principle of this instrument is: put the original sample (the large one needs to be cut into about 10×10mm block), put it into the homogeneous bag with some liquid or solvent, and repeatedly hammer on the sample homogeneous bag through the hammering plate of the instrument. Hit, generate pressure, cause oscillation, accelerate mixing, so as to achieve a uniform distribution of microbial components in the solution. This instrument is suitable for the homogeneous treatment of brain, kidney, liver, spleen and other tissues and microorganisms, and is widely used in the fields of food, medicine, clinical, molecular, toxin and bacterial detection.
The homogeneous bag for storing original sample substances and solvents is made of special materials and has been aseptically treated (users of the opened homogeneous bag should sterilize again to ensure sterility), and pass through the horizontal opening on the upper edge of the homogenizer door. The rod is clamped and sealed to avoid the overflow of the solution when the hammering plate is hammered. The beating plate of the homogenizer is constantly hammered on the homogenizing bag, and the pressure generated can crush and mix the samples in the bag. . Homogenization speed can be set programmable, each section can be set to 3~12 times/second, each section of homogenization time can be set to 1 second to 100 minutes or continuous operation, the user can make a reasonable choice according to the sample and solvent conditions, in order to To achieve a better homogeneous effect. For example: the liver timing of mice and rats is set for 3 minutes, and the medium speed is 6-10 times/second.
This instrument makes the process of extracting bacteria, cell tissue and other substances from solid samples very simple. Just add the sample and diluent into a special sterile sample bag, put it into the homogenizer, and close the door for easy setting. After that, it will automatically start to slap homogenize and complete the sample processing process. The device effectively separates particles contained in and on the surface of solid samples, homogenizes samples, and ensures that samples mixed in sterile bags are fully representative. The operation is simple, convenient and time-consuming. One-time consumption of sterile homogeneous bags, no need for tedious cleaning work after work, samples are packed in disposable sterile homogeneous bags, which can effectively prevent cross-contamination and protect the safety of operators.
