Globe Scientific's plastic micro hematocrit capillary tubes are completely unbreakable. They eliminate the risk of injury and contamination associated with glass tubes due to breakage.
Plastic micro hematocrit capillary tubes comply with FDA, NIOSH, CDC and OSHA safety recommendations
The tubes are available plain (untreated) 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:
Untreated - Blue Tip
Ammonium Heparinized - Green Tip
Sodium Heparinized - Red Tip
Inside Diameter: 0.90mm +/- 0.05mm
Outside Diameter: 1.60mm +/- 0.05mm
Length: 75mm +/- 0.5mm
Spin rate: 12,000 RPM for 4 minutes
Material: Polyethylene Terephthalate (PETG)
Only use plastic capillary tubes on micro-hematocrit centrifuge rotors that support the entire length of the tube. If the rotor only supports the tubes at two points, the tubes will bend and the sample will be lost. For rotors that support two points, use our glass capillary tubes.
If collecting anti-coagulated blood from a blood collection tube, use a plain capillary tube.
If collecting by finger stick from a patient or when using untreated blood, use capillary tubes that are treated with an anticoagulant (heparin).
