FAQ

1.How is the compatibility of capsule filters with different chemical reagents?

Our capsule filters are made of various membrane and housing materials, and the compatibility of different materials with chemical reagents varies. You can provide the specific names, concentrations, and usage conditions of the chemical reagents, and we will confirm the compatibility based on the characteristics of the filter materials or recommend a suitable filter material for filtering that chemical reagent.

2.What membrane type is used and is it compatible with my solution?

Capsule filters are engineered with a selection of membrane materials tailored to specific operational requirements. MS membrane options comprise:

• Polyether sulfone (PES), which is widely used in sterilizing-grade filtration processes.
• Polytetrafluoroethylene (PTFE), preferred for filtering aggressive gases and solvents.
• Polyvinylidene fluoride (PVDF), employed in high-criticality filtration applications.
• Polypropylene (PP), commonly applied as a robust prefiltration medium.
• Nylon, utilized for versatile and general filtration needs.

3.Is the Membrane Solutions' capsule filter sterile or non-sterile?

Membrane Solutions' Capsule filters are supplied in both sterile and non-sterile configurations to align with their intended application. The sterile variants are engineered specifically for the removal of microorganisms and are employed in processes demanding assured sterility. In contrast, non-sterile versions are utilized for general-purpose filtration, including particulate removal and liquid clarification.

4.How are Membrane Solutions' capsule filters sterilized?

Membrane Solutions' Capsule filters are sterilized by gamma irradiation to eliminate potential contamination left by residual ethanol.

5.What makes capsule filters beneficial?

Capsule filters offer several practical advantages over traditional filtration systems:

• Ready-to-use design: No need for housing or assembly
• Time-saving: Easy installation and quick change-outs
• Safe and sterile: Many options are available pre-sterilized and disposable
• Compact: Ideal for space-constrained setups
• Cost-effective: Especially suitable for single-use processes

These features make disposable capsule filters an ideal choice for regulated environments or small-batch processing.

6.How do I choose the right capsule filter model according to my specific filtration needs?

You need to consider multiple factors, such as the properties of the liquid to be filtered (including pH, viscosity, particle content, etc.), the required removal rating, the processing flow rate, and the operating conditions (such as temperature and pressure). Generally speaking, for larger - sized impurities, you can choose a filter with relatively lower removal rating; while for removing microorganisms or fine particles, a high removal rating filter is required. Our technical team can also recommend the most suitable filter model based on the detailed information you provide.

7.My equipment has a specific interface size. Can I find a compatible capsule filter?

We offer capsule filters with various interface sizes to fit common filtration equipment on the market. You can tell us the specific size and type of your equipment interface (such as sanitary clamp connections, threaded connections, etc.), and we will confirm whether we have a matching filter or provide a customized interface solution.

8.What are the key points to note during the installation of a capsule filter?

First, ensure that the installation environment is clean to prevent dust and other impurities from entering the filter. Before installation, check the filter's appearance for any damage and make sure the interface seals are in good condition. During installation, install the filter into the filtration equipment in the correct direction and ensure that the interfaces are tightly connected to prevent leakage. In the case of aseptic filtration applications, strict aseptic operating procedures must be followed during the installation process.

9.How can I tell when the capsule filter needs to be replaced?

There are several main ways to determine this. One is to monitor the pressure differential between the inlet and outlet. When the pressure differential reaches the maximum allowable value for the filter (as referred to in the product manual), it indicates that the filter may be clogged and needs to be replaced. Second, based on the filtration flow rate. If the flow rate drops significantly and cannot be restored by adjusting the equipment parameters, it may be due to severe filter clogging. Additionally, for applications with specific filtration performance requirements (such as sterilizing filtration), regular testing should be carried out. If the filtration effect does not meet the standards, the filter also needs to be replaced.

10.How often should the capsule filter be replaced approximately?

This depends on multiple factors, such as the degree of contamination of the filtered liquid, the processing flow rate, and the operating time. In cases where the contamination level is low and the flow rate is small, the filter can be used for a relatively long time; while in applications with high contamination and high flow rates, the replacement frequency will increase accordingly. It is generally recommended to regularly check the condition of the filter and determine the replacement cycle based on the actual situation. Usually, you can refer to the recommended replacement time in the product user manual as a preliminary guideline.

11.What should I pay attention to when storing capsule filters?

Filters should be stored in a dry, clean, and well - ventilated environment, away from direct sunlight and moisture. The storage temperature should be within the range specified for the product, generally at room temperature. Unopened filters should be kept in their original packaging to prevent dust and contaminants from entering. For filters with special storage requirements (such as those requiring low - temperature storage), be sure to follow the instructions in the manual.

12.How can I ensure that the capsule filter is not damaged during transportation?

During transportation, we use appropriate packaging materials to protect the filter from collision and compression. Shock - absorbing and moisture - proof packaging materials such as foam and air cushions are commonly used. At the same time, we choose reliable transportation methods and carriers to avoid exposing the filter to extreme temperature, humidity, and other harsh conditions during transit. If you transport the filter yourself, please also try to take similar protective measures.
