The WINCOM TG12A Microhematocrit Centrifuge is a high-speed, benchtop laboratory instrument manufactured by Wincom Company Ltd. . It is primarily engineered for clinical medicine, biochemistry, and blood analysis to determine packed cell volume (PCV) and separate micro-volumes of blood and solutions. [1, 2, 3]

Key Design & Safety Features
- Brushless Motor : Driven by a high-speed motor designed for stable operation, low noise, and minimal ongoing maintenance.
- Compact Tabletop Profile : Engineered with a lightweight, space-saving layout suitable for small laboratories, mobile medical vans, and school workstations.
- Safety Lid Interlock : Mechanical safety mechanism that prevents the unit from starting if the lid is unsecured and halts operation immediately upon error.
- Emergency Release : Built-in override system allowing manual retrieval of critical blood samples during an unannounced power outage.
Operating Best Practices
- Surface Placement : Operate only on a rigid, level, and entirely vibration-free laboratory bench.
- Symmetrical Balancing : Always load capillary tubes in matching pairs directly opposite each other on the rotor to ensure uniform weight distribution and prevent spindle wobble.
- Capillary Preparation : Ensure the clay or heat sealant end of each \(75\text{ mm}\) capillary tube faces outward toward the perimeter rubber gasket.
- Locking Top : Tighten the rotor’s inner retention plate firmly over the threaded central bolt to lock the capillaries securely inside their grooves before shutting the main lid.
