Normal Complete Blood Count Values
-- also called CBC
-- Hbg (hemoglobin) -- men = 13 to 18 g/dL -- women = 12 to 16 g/dL
-- WBC (white blood cell count) -- 5,000 to 11,000 /ccm
-- Hct (hematocrit) -- men = 37 to 49% -- women = 36 to 46%
-- platelets -- 150,000 to 400,000 /ml
Haematocrit Centrifuge – Guide to Packed Cell Volume Determination
Accurate packed cell volume (PCV) measurement is a fundamental parameter in hematology laboratories. From anemia screening to monitoring dehydration and polycythemia, determining haematocrit levels requires precision, speed, and consistency. A Haematocrit Centrifuge plays a central role in delivering accurate red blood cell separation for clinical interpretation.
In this comprehensive guide, we explore what a haematocrit centrifuge is, how it works, common user and how advanced systems like the Haematocrit Centrifuge LHC-A10 enhance Laboratory workflow.
What Is a Haematocrit Centrifuge?
A haematocrit centrifuge machine is a specialized high-speed Laboratory Centrifuge instrument designed to separate red blood cells from plasma in capillary tubes. It operates at high RPM to achieve rapid sedimentation, allowing clinicians to calculate the percentage of red blood cells in whole blood.
The term centrifuge haematocrit refers to the process of spinning blood samples to determine packed cell volume. Unlike a general-purpose centrifuge machine, this instrument is optimized for micro capillary tubes and short spin times.
A Microhematocrit Centrifuge is specifically designed for small-volume blood samples and is widely used in hospitals, diagnostic labs, blood banks, and research centers.
Why Packed Cell Volume Determination Matters
Haematocrit testing is critical in diagnosing and monitoring:
Anemia
Polycythemia
Dehydration
Blood loss
Chronic kidney disease
Hematological disorders
Accurate PCV results depend on uniform centrifugal force, proper sealing of capillary tubes, and controlled spin time. Inconsistent RPM or rotor imbalance can compromise results.
How a Micro Haematocrit Centrifuge Works
The micro haematocrit centrifuge operates on the principle of centrifugal force. Blood-filled capillary tubes are placed symmetrically in the rotor. When the rotor spins at high speed:
Red blood cells move outward due to density.
Plasma remains in the upper portion.
A thin buffy coat (white cells and platelets) forms between them.
After centrifugation, the length of packed red blood cells is measured against the total blood column to calculate haematocrit percentage.
This explains microhematocrit centrifuge is used for rapid PCV determination in small sample volumes.
Operational Challenges in Haematocrit Testing
Clinical laboratories often face operational challenges:
1. Inconsistent Packed Cell Volume Results
Fluctuating RPM or unstable rotors can cause uneven cell packing.
2. Tube Breakage During Spin
Low-quality rotor design or improper balancing may result in capillary tube damage.
3. Long Processing Time
Older centrifuge systems may require extended spin cycles.
4. Noise and Vibration
Excess vibration affects instrument lifespan and user comfort.
5. Limited Safety Features
Lack of lid interlock systems may pose operational risks.
A modern haematocrit centrifuge machine addresses these issues with stable high-speed rotation, secure rotor design, and integrated safety mechanisms.
Key Features of a High-Performance Haematocrit Centrifuge
When selecting a centrifuge machine for PCV testing, laboratories should consider:
High-speed capability (typically up to 12,000 RPM or higher)
Digital speed and timer control
Capillary tube rotor compatibility
Lid lock safety system
Short spin time (usually 5–10 minutes)
Compact benchtop design
Advanced models such as Haematocrit Centrifuge LHC-A10 offer optimized speed control and separation performance, supporting efficient hematology workflows.

Hematological profiling
5. Research Laboratories
Experimental hematology studies
Drug impact evaluation on RBC concentration
The versatility of a haematocrit centrifuge machine makes it essential across multiple diagnostic settings.
Difference Between Haematocrit Centrifuge and General Centrifuge
Many labs confuse a high-speed centrifuge or refrigerated centrifuge with a microhematocrit system.
Feature
Haematocrit Centrifuge
High-Speed Centrifuge
Refrigerated Centrifuge
Sample Type
Capillary tubes
Tubes, bottles
Temperature-sensitive samples
Application
PCV determination
Broad separation
Enzyme/DNA separation
Cooling System
Not typically required
Optional
Built-in refrigeration
Speed Optimization

Multi-purpose
Temperature-controlled
While a Centrifuge Machine can perform general separation tasks, a dedicated Microhematocrit Centrifuge ensures optimized packed cell volume results.
Why Choose a Dedicated Haematocrit Centrifuge?
A general centrifuge machine may not provide the uniform centrifugal force required for precise RBC packing. A specialized haematocrit centrifuge ensures:
stable cell layering
Reduced sample handling errors
Shorter processing cycles
Standardized PCV measurements
Laboratories handling high patient volumes benefit from dedicated microhematocrit systems rather than adapting multipurpose equipment.
Workflow Optimization in Hematology Labs
Modern hematology labs require faster turnaround time without compromising accuracy. Integrating a Labtron Centrifuge designed for haematocrit testing can improve:
Daily sample throughput
Technician efficiency
Quality control compliance
Reproducibility of PCV values
By minimizing manual variability and ensuring stable high-speed performance, laboratories can maintain stable diagnostic standards.
Maintenance and Operational Tips
To extend the lifespan of a haematocrit centrifuge machine, laboratories should:
Balance capillary tubes properly before each run
Inspect the rotor for wear and cracks
Clean the chamber after tube breakage
Calibrate RPM periodically
Avoid overloading beyond the specified capacity
Preventive maintenance enhances operational consistency and reduces downtime.
