HM18R High-Speed Refrigerated Centrifuge Introduction

The HM18R High-Speed Refrigerated Centrifuge is a cutting-edge solution designed for scientific research, clinical analysis, and industrial applications. Engineered with advanced technology and user-centric features, it delivers exceptional performance, reliability, and safety. Below are the key selling points that make the HM18R a top choice for laboratories worldwide:
 
1. Powerful Performance & Versatility
 
- High Speed & Centrifugal Force:
- Maximum speed: 18,000 rpm (rotor-dependent, e.g., 18R A-2 rotor achieves 16,000 rpm with 24,100×g max RCF), enabling efficient separation of dense samples.
- Wide speed range (100–18,000 rpm) and adjustable acceleration/deceleration (0–9 levels) for customized workflows.
- Precision Temperature Control:
- Refrigeration system with eco-friendly R134a refrigerant, temperature range: -20°C to +40°C (control accuracy ±2°C, display accuracy 0.1°C).
- Pre-cooling function ensures rapid temperature stabilization (e.g., cooling to 0°C in ≤15 minutes) and maintains constant temperature even with the door open to prevent ice formation.
- Large Capacity:
- Supports multiple rotors and adapters, including angle rotors (e.g., 1.5/2ml×24) and swinging-bucket rotors (250ml×4), with a maximum capacity of 1000ml (250ml×4).

2. Advanced Safety Features
 
- Multi-Level Protection:
- Unbalance Detection: Automatically stops operation if rotor load imbalance exceeds 1.5g, preventing damage and accidents.
- Over-Speed & Over-Temperature Alarms: Shuts down the centrifuge if speed exceeds the rotor’s rated max by 600 rpm or temperature deviates by +10°C.
- Emergency Door Release: Manual override for power failures or malfunctions (see Figure below), ensuring safe sample retrieval.
- Hazardous Substance Prevention:
- Prohibits flammable, corrosive, toxic, or radioactive materials; requires sealed containers for corrosive samples to protect internal components.
- Compliance & Standards:
- Meets international safety standards: GB4793.1, GB4793.7, YY/T 0657, ensuring regulatory compliance and user protection.

3. User-Friendly Design & Efficiency
 
- Intuitive Interface:
- 7-inch Color Touchscreen: Easy-to-use control panel with real-time display of speed, temperature, time, and RCF (automatically converted from speed).
- 10 Custom Memory Programs: Save and recall frequently used parameters (e.g., speed, time, temperature) for repetitive experiments, reducing setup time.
- Automatic Rotor Recognition:
- Instantly identifies installed rotors (e.g., 18R A-1 to A-14, 18R S-1 series) and displays max speed/RCF, preventing incorrect usage.
- Ergonomic Operation:
- Smooth door opening/closing with damping air springs and safety interlock (door must be locked to start).
- Low noise (<=58dB at max speed) and compact design (560×680×376mm) for space-efficient lab placement.

4. Reliability & Durability
 
- Robust Construction:
- Stainless steel inner chamber and explosion-proof door cover for corrosion resistance and safety during high-speed operation.
- Direct-drive frequency conversion motor for low vibration, high precision, and long lifespan.
- Maintenance & Service:
- Easy cleaning with neutral detergents; steam sterilization guidelines for rotors/tubes (see Table 2 in manual).
- Factory-authorized maintenance only, ensuring genuine parts and professional service.
