A low-speed centrifuge is a common laboratory device used to separate components in mixtures based on density. Its design focuses on simplicity, safety, and practicality. Below is an overview of its main parts.
Ⅰ、Housing (Casing)
The outer frame, or housing, is typically made of durable metal for strength and stability. It houses all internal components and includes safety features like a locking door mechanism. This prevents accidental openings during operation, prioritizing user safety.
Ⅱ、Rotor
The rotor is the core component that holds sample containers (e.g., test tubes). Two common types optimize different workflows.
1.Angle Rotor
Angled (30°–45°) tubes maximize centrifugal force for small-volume samples, ideal for high-efficiency separations.
2.Swing-Bucket Rotor
Horizontal tubes ensure uniform sample distribution, suitable for larger volumes or delicate samples.
Rotors are crafted from corrosion-resistant alloys like aluminum or titanium, balancing durability and weight. Proper balance is critical to avoid vibration during operation.
Ⅲ、Drive System
This powers the rotor’s rotation.
1.Motor
Brushless DC motors are energy-efficient and low-maintenance, while AC motors offer affordability for basic models.
2. Transmission
Belt-driven systems are cost-effective but require periodic maintenance. Direct-drive systems eliminate belts for quieter, more reliable high-speed performance.
Ⅳ、Control Panel
Users adjust settings via.
1.Digital Display
Shows real-time parameters like centrifuge speed, time, and temperature.
2.Interface
Buttons and knobs simplify operation.
3.Microprocessor
Ensures precise control and stability throughout the process.
Ⅴ、Vibration Dampening System
To minimize noise and wear.
1.Shock Absorbers
Rubber or spring-based mounts reduce vibrations.
2.Balancing Weights
Adjusted manually to counteract uneven loads.
Ⅵ、Summary
Low-speed centrifuges excel in routine lab tasks thanks to their straightforward design. Key advantages include adaptability for diverse samples, user-friendly controls, and enhanced safety features. By understanding these components, researchers can optimize performance for applications like blood separation or DNA extraction.
