Micro Blood Collection Tube with Capillary
Product Description
Micro Blood Collection Tube with Capillary
The Micro Blood Collection Tube with Capillary is a specialized device designed for the collection, transportation, and storage of small blood samples, typically from capillary punctures such as fingersticks, heelsticks, or earlobe punctures. It is widely used in clinical laboratories, hospitals, and point-of-care settings, particularly for pediatric, geriatric, or other patients where venous blood collection is difficult.
Structure and Components:
Micro Collection Tube: A small, cylindrical tube usually made of medical-grade plastic (such as polypropylene or PET). The tube often has a precise volume range to ensure optimal sample size for various tests.
Capillary (Capillary Straw): A thin, narrow-bore capillary tube attached or included with the collection tube, facilitating easy and direct transfer of blood from the puncture site into the collection tube by capillary action.
Closure Cap: A secure, often color-coded cap that ensures airtight sealing to maintain sample integrity and prevent leakage or contamination. Some designs integrate a membrane or septum for safe sample retrieval.
Additives (Optional): Depending on the intended test, the tube may contain anticoagulants (e.g., EDTA, heparin) or clot activators to stabilize the sample.
Features:
Designed for low-volume blood collection.
Integrated capillary allows simple, hygienic, and efficient blood transfer without additional equipment.
Color-coded caps correspond to different types of additives or test requirements.
Graduated markings on some tubes help approximate sample volume.
Leak-proof, tamper-evident cap ensures safe transport and storage.
Sterile and single-use to prevent cross-contamination.
Usage Instructions:
Perform capillary puncture using a sterile lancet.
Allow a small droplet of blood to form at the puncture site.
Place the capillary tube against the droplet; blood will be drawn into the capillary by natural capillary action.
Transfer blood into the micro collection tube by gently expelling the blood or allowing it to flow naturally.
Seal the tube with the cap.
Label appropriately and send for analysis according to laboratory protocols.
