According to the requirements of the Chinese Pharmacopoeia, drugs (such as oral preparations, topical ointments, medical devices) need to undergo strict microbiological limit testing, and the homogenization of samples directly affects the reliability of the test results. For solid drugs (such as tablets and capsules), they can be crushed and mixed with sterile diluent in a homogenization bag, and gently homogenized by equipment to avoid microbial damage; For semi-solid drugs (such as ointment and gel), the equipment can realize the full emulsification and dispersion of samples and diluents by adjusting the homogenization speed to ensure the uniform distribution of microorganisms. In addition, the temperature controlled chamber of the device can maintain a low temperature environment of 2-8 ℃, which is suitable for homogenization treatment of thermosensitive drug samples to avoid microbial inactivation caused by high temperatures. In the intermediate product testing and finished product release inspection of drug production, the sterile design and standardized operating procedures of this equipment can meet GMP certification requirements, ensuring the standardization and accuracy of drug microbiological testing.

In the field of clinical sample microbiological testing,Dreet sterile homogenizer HM400SIt provides an efficient sample treatment scheme for the diagnosis of infectious diseases. Clinically collected sputum, feces, tissue biopsy samples, etc. need to be homogenized to isolate pathogens, providing a basis for subsequent pathogen identification and drug sensitivity testing. For example, in sputum testing of patients with respiratory tract infections, the viscous nature of sputum makes it difficult for microorganisms to be released. When using this device, sputum and expectorant diluent are placed in a homogenization bag, and a targeted homogenization program is selected (10-12 levels of intensity are used for viscous samples, with a duration of 120-180 seconds), which can quickly break the mucus protein network of sputum and fully release pathogens such as Mycobacterium tuberculosis and Streptococcus pneumoniae. The sterile homogenization bag of the equipment is disposable, which can avoid cross contamination between different patient samples, ensure the accuracy of clinical test results, and provide reliable support for doctors to use medication accurately.

In the field of microbial detection in environmental monitoring, this device can achieve efficient homogenization of complex samples such as soil, water sediment, etc. In soil microbial diversity investigation and water pollution microbial detection, the sample composition is complex and the particles are uneven, making it difficult for traditional homogenization methods to achieve uniform dispersion.Dreet sterile homogenizer HM400SBy using high-strength homogenizer blades, the aggregation structure of soil particles and sediments can be broken, allowing microorganisms (such as Bacillus and nitrifying bacteria) to be fully released into the detection solution. At the same time, the sealed homogeneous design of the equipment can avoid contact between the sample and the external environment, prevent external microbial contamination, ensure that the detection results can truly reflect the distribution of microorganisms in the environment, and provide scientific data support for environmental quality assessment and pollution control.

The Dreet sterile homogenizer HM400S, with its efficient homogenization, sterile protection, and adaptability to multiple types of samples, has become a core pre equipment for microbial detection in multiple fields. Its standardized operating procedures and adjustable homogenization parameters not only ensure the stability of sample processing, but also improve detection efficiency, laying a solid foundation for the accuracy of microbial detection and helping various industries achieve precise quality and safety control.
