Microhematocrit Capillary Tubes - Globe Scientific | Color-Coded

Globe Scientific microhematocrit capillary tube products enable fast, reliable hematocrit determinations in clinical and point-of-care settings. Available in four configurations with color-coded tips for instant identification: sodium heparinized (red), ammonium heparinized (green), plain untreated (blue), and precalibrated (borosilicate). Each box contains 1000 tubes packaged in 10 vials of 100.

These precision-drawn glass capillary tubes meet the dimensional and performance requirements for standard microhematocrit centrifugation. Color-coded tip markings eliminate confusion between treated and untreated tubes during sample collection. Made in Denmark under strict quality controls for consistent capillary action and fill performance.

Microhematocrit Capillary Tube Features and Benefits

• Color-Coded Identification: Red tip (sodium heparinized), green tip (ammonium heparinized), blue tip (plain), enabling instant visual differentiation at the point of collection
• Consistent Capillary Action: Precision-drawn glass ensures uniform bore diameter for reliable blood fill and consistent hematocrit readings across every tube
• Heparinized Options: Sodium and ammonium heparin coatings prevent blood clotting during collection from capillary puncture sites without affecting test results
• Precalibrated Option: Borosilicate glass tubes with calibration marks eliminate the need for manual measurement and reduce reading errors
• Vial Packaging: 100 tubes per vial protects against breakage and contamination while allowing single-vial dispensing at workstations
• Non-Sterile: Suitable for standard hematocrit testing protocols where sterility is not required

Laboratory Applications

• Clinical Hematology: Standard microhematocrit determination by centrifugation for packed cell volume measurement in CBC panels
• Point-of-Care Testing: Rapid hematocrit assessment at bedside, in clinics, and in urgent care settings using capillary fingerstick or heelstick samples
• Veterinary Diagnostics: Small animal hematocrit testing where limited blood volume requires microsampling techniques
• Blood Bank: Pre-donation screening and donor qualification hematocrit testing at blood collection facilities
• Research: Small-volume blood sampling for hematological studies, drug metabolism, and pharmacokinetic research

Quality Assurance and Compliance

Globe Scientific microhematocrit capillary tubes are manufactured in Denmark under strict quality controls. Each production lot is tested for dimensional accuracy, capillary fill performance, and anticoagulant coating uniformity.
