Glass Micro-Hematocrit Capillary Tubes

Details

Our glass capillary tubes are designed for both safe blood collection as well as accurate micro-hematocrit determinations. Precision molded, they provide excellent sample retention during centrifugation. In addition, the tubes fill rapidly without affecting specimen integrity.

The tubes are available plain or with an anticoagulant (sodium or ammonium heparin) that keeps the blood from clotting. All of the tubes have color coded ends to easily identify the plain and heparin treated tubes.

Types of Tubes
Untreated: Blue Tip
Ammonium Heparinized: Green Tip
Sodium Heparinized: Red Tip
