# Safe-T-Fill Capillary Blood Collection Tube

The Safe-T-Fill Capillary Blood Collection Tube is designed for efficient and accurate collection of microliter volume capillary blood samples, particularly suitable for pediatric and neonatal applications. These tubes are constructed from 100% plastic and incorporate advanced features to enhance sample quality and precision in blood collection.

## Key Features
Available with different additives such as Dipotassium (K2) EDTA and Lithium Heparin, these tubes are equipped with a capillary straw and microtube both coated with the anticoagulant to prevent clotting. The attached, color-coded cap differentiates the type of additive present, ensuring clear identification during use.

### Design and Usage
Pre-assembled with a capillary straw, pierceable attached cap, and microtube, these tubes provide an easy-to-use system for capturing blood samples, minimizing hemolysis, tissue contamination, and reducing sample clotting. The design encourages a complete end-to-end fill using capillary action, optimizing the volume of the sample collected.

### Practical Application
These tubes have clear printed markings indicating lot numbers, expiration dates, and fill lines. They are particularly beneficial for procedures requiring precise capillary blood volume measurements, such as whole blood hematology determinations. The robust design ensures reliable performance across various applications.
