Features of multi-branch vacuum filtrations

1. The filter bracket part adopts a triple/six structure, which can filter at most 3/6 groups of samples at one time. At the same time, there is a valve switch under each filter funnel that can independently control the opening and closing, and the filter funnel that is not needed can be closed according to actual needs. Filtering 3 or 6 groups of samples at one time can effectively improve the efficiency of filtration experiments.

At the same time, different from the cumbersome operation of using 3 or 6 sets of filter bottles and occupying more table space, the triple filter holder is easy to operate. At the same time, in order to cope with the substantial increase in the amount of filtration for some customers in the future, we also designed a connector. Users only need to buy a bracket, and through the connector, the filter bracket can be expanded into a six-connection type, without the need to re-purchase A set of six-connected brackets and other supporting liquid collection bottles, suction filtration pumps, etc.

2. The filter funnel is made of 316L stainless steel as a whole. In addition to conventional high-temperature and high-pressure moist heat sterilization, the standard flame sterilization spray gun can also be used for rapid flame sterilization.

3. The complete set of detection and filtration system is fully equipped, including the suction filter pump host, filter bracket and funnel, flame spray gun for rapid cauterization and sterilization, filter membranes, anti-sucking water blocking protector, and connecting hoses. The complete configuration enables users to use it directly without purchasing any accessories separately after purchasing the model.

4. The suction filtration pump adopts an independent design, which has a better vacuum degree and suction filtration rate and will not have problems such as slow filtration rate and immobility due to the nature of the filtered liquid.

5. The filter cup of the filter funnel and the base part of the filter membrane is designed with a rotary clamp, which does not require the use of external accessories such as clamps and clamps. The mechanical structure of the funnel itself can be used to achieve sealing without liquid leakage and air leakage. . The design makes the funnel simple in structure, and the membrane can be changed with one hand, which is easy to operate and use.

6. The suction filter pump adopts an oil-free piston structure. The noise value during operation is low. At the same time, it has high stability.

How to choose the multi-branch vacuum filtrations

Choosing a multi-branch vacuum filtration system involves considering several factors to ensure that it meets your specific needs. Here’s a step-by-step guide to help you make an informed decision:

  1. Understand Filtration Requirements:
    • Identify the specific characteristics of the samples you will be filtering, such as particle size, chemical composition, and volume.
  2. Determine Filtration Method:
    • Decide on the filtration method based on your application. Common methods include vacuum filtration, gravity filtration, and positive pressure filtration.
  3. Select Appropriate Filtration Media:
    • Choose the right filter media for your application. Different materials and pore sizes are suitable for various types of samples.
  4. Consider Chemical Compatibility:
    • Ensure that the materials used in the filtration system are compatible with the chemicals present in your samples. This includes the filter membrane, tubing, and any other components.
  5. Capacity and Throughput:
    • Determine the volume of samples you will be processing and select a multi-branch vacuum filtration system that can handle the required capacity efficiently.
  6. Number of Branches:
    • Decide on the number of branches based on your workflow and the number of samples you need to process simultaneously. More branches can increase efficiency but may also require more vacuum power.
  7. Vacuum Source:
    • Consider the vacuum source available in your laboratory. Ensure that the vacuum pump you have or plan to acquire is compatible with the multi-branch filtration system.
  8. Ease of Use:
    • Look for a system that is user-friendly and easy to set up and operate. Quick assembly and disassembly can save time during sample processing.
  9. Maintenance and Cleaning:
    • Consider the ease of maintenance and cleaning. A system that is easy to disassemble and clean will ensure the longevity of the equipment and prevent cross-contamination between samples.
  10. Compatibility with Accessories:
    • Check if the filtration system is compatible with additional accessories or optional components that may be needed for specific applications.
  11. Budget Considerations:
    • Evaluate the cost of the multi-branch vacuum filtration system and compare it with your budget constraints. Consider not only the initial purchase cost but also ongoing maintenance expenses.
  12. Reviews and Recommendations:
    • Research and read reviews from other users who have similar filtration requirements. Recommendations from colleagues or industry experts can also be valuable.

By carefully considering these factors, you can choose a multi-branch vacuum filtration system that aligns with your laboratory’s needs and ensures efficient and reliable sample processing.

The multi-branch vacuum filtration system is suitable for food and beverage production enterprises, pharmaceutical factories, disease control centers, medical, university scientific research, or third-party testing institutions.

The principle is to install a filter membrane at a specific position of the filter device. After the sample is poured, the pressure difference generated by the vacuum pump is used to make the liquid pass through the filter membrane. After filtration, the filter membrane is placed in a petri dish for cultivation. The obvious difference from general filtration is that the number of samples to be inspected is large. The use of traditional single-connected filter bottles may result in lower filtration efficiency, while the use of professional microbial detection multi-connected vacuum filtration systems can filter out 3 groups, 6 groups, or even more samples. At the same time, due to the special needs of users, the requirements for sterility and avoiding contamination in microbiological testing are higher.

At present, there are many types of multi-unit vacuum filtration systems for microbial detection on the market. Customers can choose the products that suit them according to these items:

The number of filtered samples: the common models are generally classified according to single, triple, and hexagonal. The main difference is the number of samples that can be filtered by the user at a time, corresponding to 1 group, 3 groups, and 6 groups respectively. The unit needs to be selected by the amount of sample filtered. At present, it is recommended that customers use the triple or six vacuum filtration system for microbiological inspection in water. A vacuum filter pump is equipped with a set of triple filter brackets.

There are 3 or 6 filter cups on the bracket, which can be filtered at the same time, or the filter cup can be used. A lower valve switch closes the filter bowl when it is not in use. Its biggest feature is that when the customer needs to expand the filter base when the number of filtration samples increases in the future, he only needs to buy another triple base, and through a straight-through connector, two sets of triple bases can be connected in series, and only the originally configured one is still used. The filtration work can be realized with only one suction filter pump, and there is no need to purchase an additional suction filter pump.

Material of the filter: The material of the filter can be divided into two parts, the material of the main frame and the material of the funnel. At present, the mainstream product bracket materials are stainless steel and aluminum alloy. Whether the bracket part is aluminum alloy or stainless steel, it can be sterilized at high temperature and high pressure, while aluminum alloy has the advantage of being lightweight. The main bracket material is anode process aluminum alloy; the types of funnel materials are more divided into stainless steel, glass, plastic, ceramics, etc. Among them, the stainless steel material can be directly sterilized by flame burning, the glass material is cheap, and the plastic material has a simple, lightweight structure and is resistant to falling. increasingly widespread.
