Blood Collection Tube Microtainer Micro Blood Collection Tube
Product Description
Blood Collection Tube Microtainer Micro Blood Collection Tube
The Micro Blood Collection Tube is a small-capacity specimen container specifically designed for the collection, storage, and transportation of capillary blood samples. It is commonly used in pediatric, neonatal, geriatric, and point-of-care testing (POCT) settings, where only a small volume of blood is required for analysis.
Features:
Small Volume Collection:Designed to collect blood volumes typically ranging from 100μL to 500μL, ideal for limited blood draw situations.
Pre-filled Additive Options:Available with various additives (e.g., EDTA, Lithium Heparin, Sodium Heparin, Clot Activator, Fluoride Oxalate) for different types of blood testing (hematology, biochemistry, glucose, etc.).
Color-Coded Caps:Universal color coding according to additive type ensures easy identification and reduces the risk of sampling errors.
Secure Closure System:Equipped with a leak-proof, snap-on or screw-on cap to prevent spillage and contamination during transport and handling.
Transparent Medical-Grade Plastic:Made from high-clarity PET or polypropylene (PP) material for easy visual inspection of sample volume and quality.
Optional Collection Aids:Some designs include a micro-collection funnel, capillary straw, or integrated scoop to facilitate easier blood transfer from the puncture site into the tube.
Sterile and Single-Use:Individually sterile packed to ensure patient safety and prevent cross-contamination.
Micro Blood Collection Tube – Cap Color and Additive Table:
| Cap Color | Additive | Purpose / Application |
| Purple / Lavender | EDTA K2 or EDTA K3 | Hematology tests (e.g., CBC, blood cell counts) |
| Green | Lithium Heparin or Sodium Heparin | Plasma biochemical tests (e.g., electrolytes, enzymes) |
| Yellow | Clot Activator (sometimes with gel) | Serum collection for biochemistry, immunology, serology |
| Blue | Sodium Citrate (usually 3.2% or 3.8%) | Coagulation tests (e.g., PT, APTT) |
| Gray | Potassium Oxalate + Sodium Fluoride | Glucose and lactate measurements (glycolysis inhibition) |
| Red | No additive or Clot Activator | Serum tests (e.g., chemistry, serology) |
| Black | Sodium Citrate (higher concentration, e.g., 3.8%) | ESR (Erythrocyte Sedimentation Rate) |
| Orange | Thrombin (Rapid Clot Activator) | Rapid serum separation for urgent tests |
| Light Green | Lithium Heparin + Gel Separator | Plasma separation for chemistry tests |
| White (Pearl) | EDTA + Gel Separator | Molecular diagnostic tests (e.g., PCR, DNA analysis) |
