An Overview of Multi-Branch Stainless Steel Vacuum Filtration

The whole system of stainless steel vacuum filtration consists of a multi-branch filter, microporous filter membrane, and portable suction device. The multi-branch filter consists of several cup filters, such as one, triple, and six. So we have Single-Branch Vacuum Filtration Manifold, Triple-Branches Vacuum Filtration Units, and 6-Branches Buchner Funnel Vacuum Filtration for your choose. They are all made of 304 or 316L stainless steel and are widely used in biological, pharmaceutical, and other industries. When using, you can choose any one, two, or all of them. Valves can also be assembled according to customer requirements.

1. Materials

Stainless Steel Construction: Filtration systems made of stainless steel are known for their durability, corrosion resistance, and suitability for a wide range of applications.

2. Applications of multi-branch stainless steel vacuum filtration

It is widely used in the microbial detection of filter membrane method in research units, inspection and quarantine institutions, quality control institutions, natural mineral water industry, drinking water industry, pharmaceutical industry, beverage industry, etc. The HAWACH stainless steel filtration system has the advantages of safety and reliability, performance, beautiful appearance, environmental protection, high efficiency, energy-saving, etc. It is one of the laboratory equipment in the field of microbial research and microbial quality monitoring and testing.

The sterile microporous filter membrane is placed on the support network of the filtration system, and the microorganisms contained in the sample are intercepted and enriched on the filter membrane by vacuum filtration. Then the filter membrane is attached to the corresponding medium to cultivate corresponding colonies.

3. Advantages

  • Chemical Resistance: Stainless steel is resistant to corrosion, making it suitable for use with a variety of chemicals.
  • Ease of Cleaning: Stainless steel surfaces are easy to clean and sterilize, important in applications where cleanliness is critical.
  • Longevity: Stainless steel filtration systems have a longer lifespan compared to some other materials, providing a cost-effective solution in the long run.

4. Features of multi-branch stainless steel vacuum filtration

1) Stainless steel filter membrane buckle, easy to operate with one hand and pick and place of the filter membrane, easy to operate and more efficient to use.

2) Modular design: The connection parts of the filtration system are equipped with independent switches, which can independently filter a single sample or filter multiple samples at the same time, and can save time if many samples need to be tested. In the filtration process, an integrated solution is adopted, which is equipped with a pollution-free oil-free piston vacuum pump and a high-temperature sterilizable liquid storage bottle. The entire filtration system can be safely placed and operated efficiently in laboratories, clean rooms, and ultra-clean benches.

3) Prevent secondary pollution: The filter system has ventilation holes on the upper cover of the stainless steel filter cup, and an optional air filter can be installed to avoid secondary pollution during suction filtration.

4) Improve detection efficiency: The sterilization method of stainless steel filter can be sterilized by moist heat at 121℃ for 20-30 minutes, dry heat at 180℃ for 60 minutes, or more efficient sterilization method: use the optional filter system. Flame sterilizer, sintering at high temperature to achieve the purpose of sterilization. The inner wall of the filter bowl has a clear volume scale line, which is convenient for quantitative addition.

5) Durable material: The main accessories such as filter, filter connector, valve, filter holder, filter cover, and filter membrane support pad are all made of 316 high-quality stainless steel, which is not easy to be damaged. A high-quality 316L sintered stainless steel filter membrane support pad is preferred to ensure that the filter membrane does not rupture or perforate during the suction filtration process, to ensure the accuracy of sample detection, and to make the trapped microorganisms evenly distributed on the surface of the filter membrane. Consistent, easy to observe the experimental results.
