The Wincom JSH-120 Micro Hematocrit Centrifuge is a high-speed tabletop laboratory instrument manufactured by Wincom Company Ltd.. It is specifically engineered to determine volume fractions of erythrocytes in blood (Packed Cell Volume/PCV) and to separate micro-volumes of blood and solutions.
Core Technical Specifications
- Maximum Speed: 0 to 12,000 rpm (adjustable).
- Maximum Relative Centrifugal Force (RCF): 15,300 × g.
- Rotor Capacity: Accommodates 24 capillary tubes measuring 1.5mm x 75mm.
- Mechanical Timer: Adjustable range from 0 to 10 minutes (some variants extend up to 30 minutes).
- Structural Design: Desktop build featuring a durable alloy and metal casing.
- Certifications: ISO certified for quality management systems.
Functional Applications
- Packed Cell Volume (PCV): Isolates red blood cells from plasma via high-speed centrifugal rotation.
- Clinical Testing: Provides essential data for biochemistry, immunity, genetics, and hematology analysis.
- Target Facilities: Deployed widely in medical schools, hospitals, and clinical laboratories.
Comprehensive Components & Design
- Rotor Assembly: Precision-machined aluminum disk with 24 numbered radial slots.
- Numbered Slots: Channels are numbered 1 through 24 to track individual patient samples.
- Interlocking Lid: Screw-on inner metal rotor lid secures capillary tubes during high-speed runs.
- Safety Lock: Mechanical chassis latch prevents lid opening while the rotor is spinning.
- Drive Motor: Heavy-duty brush motor engineered to withstand high torque requirements.
Standard Operational Workflow
- Tube Filling: Fill micro-capillary tubes \(2/3\) to \(3/4\) full with anti-coagulated blood.
- Sealing Ends: Seal the clean end of each capillary tube using specialized sealing clay.
- Rotor Loading: Place tubes radially into the slots with the sealed ends facing outward.
- Balance Rule: Always load tubes symmetrically in pairs directly opposite each other.
- Lid Tightening: Screw the internal rotor plate lid down firmly before closing the main cover.
- Parameter Settings: Turn the speed knob to 12,000 rpm and set the mechanical timer for 5 minutes.
- Post-Run Phase: Allow the rotor to come to a complete stop naturally before unlocking the lid.
