Ultrassay Paddle Blender/Homogenizer, also known as a sterile homogenizer, can directly extract bacteria from solid samples. Simply add the original sample (larger samples should be cut into pieces of approximately 10×10 mm) and diluent into a sterile sample bag, then place the bag into the stomacher. Through the pounding action of paddles, pressure is generated, causing oscillation and accelerating mixing, thereby achieving a uniformly distributed state of microorganisms in the solution and completing sample processing. It effectively separates microorganisms both inside and on the surface of solid samples, ensuring complete homogenization within the sterile bag. The homogenized sample serves as a representative of the original and can be used for subsequent analysis, eliminating risks of sample alteration and cross-contamination. Using disposable sterile filter bags provides isolated operation, ensuring hygiene and safety. Since the sample does not contact the instrument, there is no leakage, thus eliminating the need for system cleaning. This method is convenient, rapid, accurate, and gentle on samples, with minimal contamination risk, no damage, no temperature rise, no sterilization or instrument cleaning required, and offers excellent reproducibility.
