Multi-Sample Blood Collection Needles (Pen Needles)
View Details
Product Overview
Manufactured in ISO 13485-compliant cleanrooms and bearing CE mark, XINLE ACD Blood Collection Tubes provide a highly sterile, pyrogen-free, and standardized closed system for the collection, preservation, and transport of whole blood specimens.
The proprietary Acid Citrate Dextrose formulation offers dual functionality: the citrate acts as an effective chelating agent to prevent blood coagulation, while the dextrose (glucose) fuels cellular metabolism. This mechanism ensures maximum cell viability and high-molecular-weight DNA integrity, supporting extended sample preservation at 2–8°C for up to 21 days before downstream pre-analytical processing.
Key Features & Biological Advantages
- Superior Cell & DNA Preservation: Maintains high-fidelity cell viability and DNA stability, critical for accurate molecular and immunogenetic testing.
- Extended Pre-Analytical Window: Safely preserves whole blood specimens at 2–8°C for up to 21 days, facilitating long-distance cold-chain transportation and biobanking.
- Sterile & Pyrogen-Free: Strict manufacturing controls minimize endotoxin contamination risks, ensuring safe sample handling and uncompromised cellular assays.
- Standardized Vacuum Collection: Automatically draws the exact required blood volume via vacuum, eliminating manual syringe errors and maintaining the precise blood-to-additive ratio.
- Formulation Options: Available in various anticoagulant formulations, including ACD, CPD, and CPDA, to meet specific laboratory, blood bank, and research requirements.
Clinical & Research Applications
ACD tubes are primarily utilized for specialized testing requiring viable blood cells and intact DNA:
- Blood Bank & Transfusion Research: Blood collection, long-term storage, and transfusion-related studies in blood centers and cord blood banks.
- HLA Typing & Tissue Matching: Preserving lymphocyte integrity for critical donor-recipient HLA matching in organ transplantation and bone marrow registries.
- DNA Paternity Testing & Forensics: Preserving high-molecular-weight DNA integrity in blood samples for legal paternity and forensic identification tests.
- Flow Cytometry Immunophenotyping: Maintaining viable cells for accurate cell surface marker analysis in flow cytometry.
Note: This product is designed to be used in conjunction with standard disposable venous blood collection needles.

Frequently Asked Questions (FAQ)
A: Yellow cap, which is the internationally recognized color code for ACD tubes.
A: Immediately invert gently 5–8 times after blood collection. Avoid vigorous shaking to prevent mechanical hemolysis of the red blood cells.
A: The unused tubes should be stored at 4–25°C. The shelf life is 12 months (refer to the specification sheet). Always check package integrity and the expiration date before use. (Note: Once the blood sample is collected, the specimen can be preserved at 2–8°C for up to 21 days).
A: Yes. Because ACD is a liquid anticoagulant, the tube must be filled to the designated mark to maintain the proper blood-to-additive ratio, otherwise, test results may be adversely affected.
A: Yes, removing the stopper alters the pH and may affect specific test results (e.g., Ca²⁺, ACP). Keeping the tube sealed also reduces the risks of external contamination and sample evaporation.
A: The specimen should ideally be delivered to the laboratory within 2 hours. During transit, avoid direct light, extreme temperatures, shaking, and hemolysis to ensure optimal sample quality.
