Why Choose DaJiMed?

Our advanced filtration technology ensures maximum leukocyte removal with minimal impact on blood components.

Better WBC Adsorption Capability

Our modified polymer structure enhances surface tension and reduces hydrophobicity, increasing contact area with blood. This significantly improves white blood cell adsorption through selective activation and cross-linking.

Selective Adsorption Capability

DaJiMed’s filter membrane specifically targets WBCs using tailored coating solutions and irradiation doses, preventing platelet activation in apheresis, pooled platelets, and PRP.

Superior Blood Biocompatibility

Gamma ray irradiation combined with polymer multi-modification ensures hydrophilic surfaces and thermal stability, minimizing dissolution and protecting RBCs during filtration.

Our Technology

Cutting-edge polymer modification and irradiation techniques ensure optimal performance and safety.

Advanced Polymer Modification

We utilize gamma ray irradiation combined with multi-modification of polymers to enhance membrane hydrophilicity, thermal stability, and surface smoothness. This reduces protein adsorption and prevents damage to red blood cells during filtration.

Selective Coating & Dosing

By adjusting irradiation dose and using specific coating solutions, we tailor the filter membrane to selectively adsorb leukocytes while preserving platelet integrity—critical for platelet-rich plasma (PRP) and apheresis applications.
