Point-of-care testing centers
Pediatric and neonatal units
Home healthcare services
Research laboratories
Mobile diagnostic units
In all these environments, the micro blood collection funnel supports accurate and hygienic micro-volume blood collection.
Understanding the structure of a micro blood collection funnel helps users appreciate its precision engineering.
The top opening is wide enough to easily capture blood drops without requiring perfect alignment. This design reduces user error.
The tapered stem guides blood smoothly into the collection tube, preventing splashing or backflow.
Some funnels are designed to fit directly onto micro collection tubes, creating a secure and stable connection.
Advanced designs include micro air vents to ensure smooth blood flow without pressure buildup.
This thoughtful structure ensures that each micro blood collection funnel performs reliably in real clinical conditions.
Material selection is crucial for safety, compatibility, and performance.
Most micro blood collection funnels are made from polypropylene (PP) or polyethylene (PE), which offer:
Excellent chemical resistance
Low protein binding
High transparency
Sterilization compatibility
High-quality funnels are latex-free and BPA-free, making them safe for sensitive patients and compliant with global medical standards.
Micro blood collection funnels are typically compatible with:
Gamma irradiation
Ethylene oxide (EO) sterilization
These material properties ensure consistent performance without compromising sample integrity.
Proper usage ensures maximum benefit from a micro blood collection funnel.
Place the micro collection tube securely on a flat surface or tube holder.
Insert the micro blood collection funnel into the tube opening or position it directly above the tube.
After performing the fingerstick or heel stick, allow blood to flow naturally into the funnel.
Ensure blood flows smoothly through the funnel into the tube without overflow.
Once the required volume is collected, carefully remove and dispose of the funnel according to biohazard protocols.
This simple process demonstrates how a micro blood collection funnel improves efficiency and cleanliness.
