Capillary Or Hematocrit Tubes
Capillary Or Hematocrit Tubes For Micro-Volume Sampling
Capillary or hematocrit tubes are used for accurate small-volume liquid handling, blood analysis workflows, micro-sampling and routine laboratory transfer tasks. This category includes Microcaps disposable glass micropipettes in volumes from 0.25 µL to 200 µL, plus Hirschmann Laborgeräte haematocrit capillaries in 75 µL formats for single-use blood centrifugation workflows.
- Glass Micropipettes: Suitable for precise liquid transfer where very small measured volumes are required.
- Haematocrit Capillaries: Used for blood sample centrifugation and haematocrit testing workflows.
- Heparinised Options: Support blood collection workflows where anticoagulant-treated capillaries are required.
- Non-Heparinised Options: Suitable for methods where untreated capillary tubes are specified.
- Disposable Formats: Single-use packs help reduce cross-contamination risk and simplify routine laboratory handling.
Choosing Capillary Or Hematocrit Tubes
When selecting capillary or hematocrit tubes, confirm the required volume, glass type, heparinisation status, pack quantity, intended sample type and compatibility with the testing method. Cole-Parmer, Kinesis and Labfriend options support laboratories that require small-volume transfer, haematocrit testing, micro-sampling and disposable liquid handling consumables.
Related Liquid Handling And Sample Preparation Categories
Capillary tubes are often purchased with other consumables used in sample handling and clinical preparation. Related categories include chromatography syringes, Pasteur or transfer pipettes and centrifuge tubes. These categories help procurement teams support workflows across blood testing, liquid handling, micro-volume dosing and laboratory preparation.

Frequently Asked Questions
What Are Capillary Or Hematocrit Tubes Used For?
Capillary or hematocrit tubes are used for small-volume liquid handling, blood sample collection, haematocrit centrifugation workflows and precise micro-sampling in laboratory settings.
What Is The Difference Between Heparinised And Non-Heparinised Capillaries?
Heparinised capillaries contain anticoagulant treatment for blood collection workflows, while non-heparinised capillaries are untreated and used where the method does not require anticoagulant.
How Do I Choose The Right Glass Micropipette Volume?
Select the volume based on the method and sample size. Low-volume micropipettes suit very small dosing or transfer tasks, while higher-volume options suit larger micro-sampling requirements.
