Globe Scientific 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
The tubes fill rapidly without affecting specimen integrity
The tubes are available plain (untreated) or with an anticoagulant (sodium or ammonium heparin) that keeps the blood from clotting
All of the soda lime glass tubes have color coded ends to easily identify the plain and heparin treated tubes:
Untreated - Blue Tip
Ammonium Heparinized - Green Tip
Sodium Heparinized - Red Tip
