Glass capillary tubes are designed for both safe blood collection as well as accurate micro-hematocrit determinations

• IØ: 1.15 mm (±0.05 mm)
• OØ: 1.5 mm (±0.05 mm)
• Length: 75 mm (±0.05 mm)
• Volume: 75 µl
• Spin Rate: 14500 rpm for 5 Minutes

Tubes are available plain or with an anticoagulant (sodium or ammonium heparin) to prevent blood from clotting. All tubes feature color-coded ends to easily identify the plain and heparin treated tubes.

Precision molded, tubes provide excellent sample retention during centrifugation. In addition, the tubes fill rapidly without affecting specimen integrity.
