Micro-Hematocrit Capillary Tubes – 200/box

Micro-Hematocrit Capillary Tubes (200/box)

Micro-Hematocrit Capillary Tubes are precision glass capillaries designed for collecting small-volume blood samples and preparing micro-hematocrit determinations in clinical and laboratory workflows. Commonly used with fingerstick or heelstick specimens, these tubes support efficient sample uptake by capillary action and help standardize packed cell volume (PCV) testing when used with appropriate sealants and a micro-hematocrit centrifuge. Packaged 200 per box, they are well suited for routine use in physician offices, clinics, hospital laboratories, and point-of-care testing environments where consistent sample handling is essential.

Intended Use

These capillary tubes are intended for clinical sample collection of whole blood in micro quantities, typically to perform hematocrit/PCV analysis and related micro-centrifugation procedures. They may also be used for other laboratory applications that require controlled micro-sample transfer, when validated by the laboratory’s protocols. For best results, use only with compatible centrifuge rotors, tube sealant/clay, and reading devices in accordance with your facility’s procedures.

Key Features

• Capillary action sampling: Facilitates rapid filling from a small blood droplet to help reduce handling steps.
• Consistent geometry: Manufactured to support reproducible results and reliable packing during centrifugation.
• Clean, smooth ends: Designed for safer handling and improved filling performance when proper technique is used.
• Clinic-friendly packaging: 200 tubes per box supports daily testing needs and streamlined inventory control.
• Compatible workflow: Intended for use with standard micro-hematocrit centrifuges and sealing compounds.

Tube Types and Identification

Micro-hematocrit capillary tubes are commonly offered in two formats: heparinized tubes for capillary blood collection (to help reduce clotting during collection) and plain tubes for use with anticoagulated specimens as defined by laboratory protocol. Many laboratories use color-coded end markings or rings to differentiate types. Confirm the tube type, marking, and compatibility with your procedure prior to collection to help ensure appropriate specimen integrity and accurate test outcomes.

Clinical Handling and Safety Notes

• Use standard precautions when collecting and handling blood specimens.
• Seal the filled tube promptly with an appropriate sealant before centrifugation.
• Inspect tubes prior to use; do not use if damaged, cracked, or contaminated.
• Dispose of used tubes in approved sharps containers according to local regulations.
