What Success Stories Can We Share?
Discover how our products are applied in real-world scenarios through our case studies.
Case 1: A Biotechnology Company Optimizes Sterile Filtration Process, Reduces Procurement Costs While Ensuring Filtration Performance
Client Background:
A biotechnology company specializing in vaccine R&D and production has long purchased 0.22 μm PVDF filter membranes for sterile filtration. In the context of fluctuating raw material prices and uncertain procurement cycles, the company sought a more cost-effective and stable alternative that would not compromise product quality.
Procurement Process and Collaboration Highlights:
The client specified key requirements for the filter membrane: strong hydrophilicity, high bacterial retention capacity, and good compatibility.
Our technical team recommended a suitable 0.22 μm hydrophilic PVDF filter membrane based on their process parameters and provided multiple sample batches for on-site validation.
We worked with the client's quality team to provide complete technical specifications, batch COAs, filtration validation data, and other support to ensure smooth integration into their quality system.
Usage Feedback:
The filter membrane successfully passed the sterile filtration validation, with filtration efficiency consistent with the previously used product.
Average procurement costs significantly decreased, delivery cycles were shortened to within 3 working days, and inventory management became more flexible.
Client Review:
"The product performed excellently in terms of performance, documentation support, and supply responsiveness, improving our overall supply efficiency. The collaboration experience was very good."
Case 2: A Testing Laboratory Bulk Purchases Filter Paper for Routine Water Quality Analysis
Client Background:
An environmental testing laboratory regularly uses qualitative and quantitative filter papers for water quality solid suspended solids and heavy metal residue testing, with strict requirements for the filtration efficiency and purity of the filter paper.
Procurement Requirements and Solution:
The client had specific standards for ash content and pore size uniformity.
We recommended 110 mm quantitative filter paper (ash content < 0.01%) and qualitative medium-speed filter paper based on the types of experiments.
We provided technical parameters, batch test reports, and compliance certifications to quickly pass the client's procurement approval process.
Usage Feedback:
The filter paper performed stably in atomic absorption and titration experiments without any background contamination.
The packaging was tight, making bulk storage and usage easy.
Client Feedback:
"The product performance fully met our experimental needs, and the price was more cost-effective than our previous supplier. It has been included in our annual centralized procurement list."
Case 3: A Large Chemical Enterprise Custom Bulk Purchases Filter Cartridges for Solid-Liquid Separation Systems on Production Lines
Client Background:
A fine chemical enterprise with an annual production capacity of 10,000 tons needed high-flow filter cartridge systems for long-cycle operation in their production line. The original filter cartridges in the equipment frequently clogged, and the operating pressure was high, leading to frequent downtime and affecting production capacity.
Procurement Pain Points and Solution Strategy:
The client had strict requirements for filtration accuracy (10 μm) and flow rate.
After understanding the operating conditions on-site, our engineering team recommended using PP pleated filter cartridges, with customized housing structure and interface types.
We provided sample testing and also offered Filter Validation services to ensure it met continuous operation requirements.
Usage Feedback:
The new filter cartridges extended the replacement cycle from the original 3 days to over 10 days.
The company saved over 20 hours of maintenance time each month.
Client Feedback:
"Your technical support team is very professional, and this custom solution has saved us considerable labor and downtime costs."
Frequently Asked Questions (FAQ)
How do I choose the right filter membrane type and pore size for my experimental application?
When selecting a filter membrane, it should be based on the filtration purpose, sample type, and the required particle retention size:
- For sterile filtration, we recommend using hydrophilic membranes with a pore size of 0.22 μm, such as PES, PVDF, NY, etc.;
- For particle removal or pre-filtration, membranes with a pore size of 0.45 μm or larger can be used;
- If filtering strong acids, strong bases, or organic solvent solutions, special attention should be paid to the chemical compatibility of the membrane material. For example, PTFE is suitable for highly corrosive solutions, while NY is more suitable for aqueous samples.
If you're unsure about which to choose, we can provide an application scenario analysis and recommend the most suitable membrane material and structure.
Are the filter cartridges you offer compatible with our filtration equipment?
We provide filter cartridges in various structures and interface types, including general-purpose, insert-type, threaded, and snap-fit, which can be adapted to most filtration equipment on the market.
If customers use custom equipment or older models, we also support non-standard customization based on dimension drawings or physical samples to ensure seamless installation and consistent performance. Our technical team can provide interface compatibility consultation and sample testing support.
Why does the filtration speed of filter paper slow down or clog during experiments?
The filtration speed of filter paper is influenced by several factors, including:
- Filter paper pore size being too small or unsuitable for the target sample;
- High particle content in the sample, leading to rapid clogging;
- Filter paper material being incompatible, leading to sample adsorption or precipitate formation.
It is recommended to choose the appropriate qualitative or quantitative filter paper based on the sample characteristics and to pre-filter high-turbidity samples. We can offer particle analysis services and recommend suitable filter paper types and pretreatment solutions.
Can you provide quality verification documents for your filter membranes or cartridges?
Of course. All of our filter membranes and cartridge products can provide the following documents (based on customer requirements):
- Batch COA (Certificate of Analysis)
- Material compatibility chart
- Microbial challenge test results (if applicable for sterile filtration)
- Complete quality system certification documents (such as ISO 9001, GMP applicability statement)
If customers perform validation experiments, we also offer Filter Validation Services, including flow rate tests, pressure hold tests, and retention efficiency verification, ensuring that the products meet laboratory and regulatory requirements.
Can you perform a filter material performance analysis if we experience unstable filtration efficiency in our experiment?
Yes, we offer professional Filter Analysis Services, which can analyze filter material pore size distribution, flux, pressure resistance, chemical stability, and other indicators.
If customers provide used filter membranes or cartridges, we can also perform failure analysis (e.g., clogging source determination, particle load capacity assessment) to help optimize filtration conditions or adjust material selection.
This service is widely used in pharmaceutical analysis, chemical filtration, food testing, and other experimental scenarios, helping to improve experimental reproducibility and result reliability.
