Safe-T-Fill Capillary Blood Collection Tube with Clot Activator and Separator Gel
This convenient case of 500 capillary blood collection tubes provides an efficient solution for microliter volume blood sampling. Each tube is pre-assembled with a capillary straw and attached pierceable cap, designed specifically for capillary blood collection from finger and heel sticks.
Advanced Capillary Collection Technology
The 100% plastic tubes utilize capillary action to draw blood samples directly into the microtube, eliminating the need for scooping or milking techniques. This innovative approach significantly reduces hemolysis, minimizes tissue contamination, and decreases the likelihood of re-draws.
Reliable Serum Separation
Featuring a clot activator coating and separator gel additive, these tubes facilitate efficient clotting and create a reliable barrier between blood and serum after centrifugation. The gel separator ensures clean serum samples for accurate chemistry determinations.
Quality and Convenience Features
- Color-coded red cap for easy additive identification
- Lot number, expiration date, and fill lines printed directly on microtube
- Complete end-to-end fill of capillary straw ensures accurate 200 µL volume measurement
- Kaolin coated tube for optimal clot activation
- Designed for use with 4,000xG centrifugation
The clear plastic tube construction allows for easy visual inspection of sample quality, while the attached pierceable cap provides secure closure and convenient access for laboratory processing.
