  • 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

Technical Information:

  • Inside Diameter: 1.15mm +/- 0.05mm
  • Outside Diameter: 1.5mm +/- 0.05mm
  • Length: 75mm +/- 1mm
  • Volume: 75uL
  • Spin rate: 14,500RPM for 5 minutes
