CPDA-1 preserves whole blood and packed red blood cells for up to 35 days at 2°C to 6°C by maintaining ATP levels and providing dextrose for ongoing cell metabolism. SAGM additive systems store red cells separately from plasma, preserving red cell viability for up to 42 days with a low hematocrit (55%–65%). This longer storage window provides an extra 7 days of shelf life that helps reduce blood wastage in regional blood centers.
| Formulation Parameter | CPDA-1 Blood Bag System | SAGM Additive Blood Bag System |
|---|---|---|
| Anticoagulant / Additive Chemistry | Citrate, Phosphate, Dextrose, Adenine (Single solution) | Primary CPD collection + Secondary SAGM Additive Solution |
| Maximum Red Cell Shelf Life | 35 Days (Stored at 2°C – 6°C) | 42 Days (Extended 7-day clinical window) |
| Red Cell Hemolysis Rate | < 0.8% at day 35 | < 0.4% at day 42 (Superior membrane preservation) |
| End-of-Storage ATP Viability | > 56% ATP maintenance | > 65% ATP maintenance (Higher post-transfusion survival) |
| Component Processing | Whole blood or packed red cells + plasma | Red blood cells + Platelet concentrate + Cryoprecipitate |
| Available Bag Configurations | Single (350/450ml), Double (450/300ml) | Triple (450/300/300ml), Quadruple (450/300/300/300ml) |
Blood storage bags must remain flexible at freezing temperatures (-80°C for cryoprecipitate and plasma) while allowing oxygen and carbon dioxide to diffuse freely across the container wall to sustain living cells.
Manshav Impex blood collection bags use medical-grade, high-molecular-weight plasticized PVC: - Calibrated Gas Permeability: Optimized membrane thickness balances CO2 release against moisture loss, preventing pH shifts in stored blood. - Ultra-Smooth Internal Surfaces: Extruded with mirror-polished tooling to prevent micro-clot initiation or platelet activation on container walls. - High-Flow 16G Phlebotomy Needle: Ultra-thin wall, siliconized needle tip with tamper-evident protector ensures rapid, comfortable donor blood flow without hemolysis.
Importing medical devices into Sri Lanka requires licensing under the National Medicines Regulatory Authority (NMRA) Act No. 5 of 2015.
Key submission requirements include: 1. NMRA Sample Evaluation: Submitting finished sample units to the National Blood Transfusion Service laboratory in Narahenpita, Colombo, for physical seal and chemical testing. 2. ISO 3826 Compliance: Test reports verifying conformity with ISO 3826-1 (Plastics collapsible containers for human blood and blood components). 3. Biocompatibility Certification: Full compliance testing under ISO 10993, verifying that plasticizer migration (DEHP or alternative DINCH) remains within safe international limits. 4. Sterility Assurance: Validated steam autoclave sterilization under ISO 17665, ensuring zero moisture loss or solution concentration shifts during thermal processing.
Blood bags with integrated diversion pouches and vacuum tube adapters help blood centers collect the first 20 to 30 ml of donor blood into test tubes for viral screening (HIV, Hepatitis, Syphilis) before the main bag fills. This diverts skin plug bacteria away from the collection bag, significantly reducing transfusion-transmitted sepsis risks.
Manshav Impex manufactures CE-certified CPDA-1 and SAGM blood collection bags, blood transfusion giving sets, and phlebotomy needles with direct shipping routes to the Port of Colombo. Contact our South Asia export team for NMRA tender documentation.

"In transfusion medicine, a blood bag is not a passive container; its chemical balance is what preserves the donor's gift of life."

Mannitol acts as an osmotic stabilizer that protects red blood cell membranes, preventing cell swelling and reducing spontaneous hemolysis over 42 days of cold storage.
A 350ml bag contains 49ml of anticoagulant solution for donors weighing between 45 and 50 kg. A 450ml bag contains 63ml of anticoagulant solution and is standard for adult donors weighing over 50 kg.
Ocean container sailings from Port Mundra (INMUN1) or Nhava Sheva (INNSA1) reach the **Port of Colombo (LKCMB)** in just **3 to 4 days**, offering one of the fastest international shipping turnarounds available.
Yes. Our transfer bags are manufactured from cold-crack-resistant polymers that safely endure freezing down to -80°C for Fresh Frozen Plasma (FFP) and cryoprecipitate storage.
Each set of blood bags is sealed in a clear, multi-layer laminated barrier pouch that prevents moisture evaporation from the anticoagulant solution, packed inside heavy-duty cartons with moisture indicators. ---
