What should I pay attention to when purchasing a sterile homogenizer?

Shanghai Billan aseptic homogenizer purchase.

Sterile homogenizer, also known as tapping homogenizer, is mainly used for tissue dispersion in the field of biotechnology, sample preparation in the pharmaceutical field, enzymatic treatment in the food industry, and in the pharmaceutical industry, cosmetics industry, paint industry and petrochemical industry. . The device adopts a stainless steel system, which can effectively separate the surface of the sample of the protector and the uniform sample of the microorganisms contained therein. The sample is placed in a disposable sterile homogenized bag, which is not in contact with the instrument, and is fast, accurate and homogeneous. Soft, no pollution, no damage, no heat, no need for sterilization, no need to wash the characteristics of the utensils, good repeatability requirements. This product is also suitable for the homogenization of tumor tissues (such as intestinal cancer, stomach cancer, liver cancer, breast cancer), which can obtain a large number of single cells (up to 2 × 105 in 2 minutes), and if necessary, by extending the homogenization time, Soft breakage of tissue cells.

1. Minimum test consumption: the smaller the better, the material can be saved. At present, the raw materials of some medicines reach several thousand yuan / gram, and users of course hope to complete a homogenization experiment with a minimum of materials. Moreover, the experiment is a process of repeated iterations. The minimum amount of sample is, the more materials are wasted.

2. Homogeneous pressure: The higher the maximum working pressure, the better. First of all: In a sense, the higher the pressure, the smaller the particle size of the material can be processed. Second, the higher the pressure, the more types of materials can be processed. For example, some liquid emulsions only need to be 15,000 psi. It can be homogenized to below 100 nm, and some medicines, foods, especially liquids with a certain amount of solid particles in suspension, then at least 26,000 psi pressure to achieve nanoscale.

3. Processing effect: The user is of course the material that he hopes to make. One is the degree of nanometer level, and the other is nanometer level. The distribution is very uniform, instead of some particles are already dozens of nanometers, and some are still Micron. In order to solve this problem, it is recommended that the user purchase a homogenizer, and the manufacturer is equipped with a nano-scale filter extruder device, preferably an in-line extruder, which is troublesome to extrude offline.

4. Cleaning and sterilization: The imported high-pressure homogenizer is convenient for cleaning and sterilization. It is recommended to consider cleaning and sterilization online.

5. Do not consider the noise, safety, and the number of users in China. From the user list, you can determine whether a device is selling well. The more well-known users, the better the quality of this device.

6. Manufacturers of homogenizers generally say that their equipment is very good. It is recommended that they provide a list of users and provide them with relevant results and papers.
