Product Description: flapping homogenizer, also known as sterile homogenizer, can directly extract bacteria from solid samples. Just cut the original sample (the large one needs to be cut into about 10 × 10mm block) and diluent are added into the sterile sample bag, and then the sample bag is put into the flapping homogenizer. After the flapping and hammering of the blade, pressure is generated, oscillation is caused, and mixing is accelerated, so that the microbial components in the solution are evenly distributed, and the sample processing can be completed. Effectively separate the homogeneous samples of microorganisms contained in the interior and surface of solid samples, and ensure that all samples are mixed in sterile bags. After homogenization, the sample can be used as a representative original for subsequent analysis, without the risk of sample changes and cross contamination. The disposable sterile homogeneous filter bag is used for isolation operation to ensure hygiene and safety, no contact with the instrument, no sample leakage and no need for systematic cleaning. It has the characteristics of convenience, speed, accurate results, soft homogenization, small sample pollution, no damage, no heating up, no sterilization treatment, no need to wash utensils, and good repeatability.
