Designed for efficient collection of capillary blood samples from finger and heel sticks, utilizing 100% plastic construction for safety and durability.
These tubes serve as a modern replacement for traditional glass Natelson, Caraway, or mylar-coated glass microhematocrit capillary tubes, eliminating the risk of breakage.
Capillary action facilitates the blood draw into the tube seamlessly, mirroring the performance of glass tubes without their associated hazards.
Our microhematocrit capillary tubes are untreated, providing versatility for various testing requirements.
Options are available with anticoagulant coatings such as Ammonium Heparin or Sodium Heparin to prevent clotting, catering to specific testing needs.
