Herolab MicroCen M/ MicroCen MR microliter centrifuges
The Herolab MicroCen M/ MicroCen MR microliter centrifuges are compact, powerful devices for precise and efficient centrifugation processes in modern laboratory environments. They are ideal for research facilities, diagnostic laboratories and industrial applications where high rotation speeds and reliable test results are essential. Compared to similar high-performance laboratory centrifuges, such as the Sigma 1-14 centrifuge, these models impress with their flexible features and sophisticated safety functions.
Versatile application options and key features
Reliability and ease of use are the key features of these modern centrifugals. Users can use both the uncooled MicroCen M variant and the cooled MicroCen MR model to suit their specific requirements profile. Similarly versatile devices such as the Sigma 3-30KS also show how high speeds and different rotor types can be used for precise analysis. However, the microliter centrifuges presented here also impress with:
- High speeds of up to 16,000 min-¹ (MicroCen M) or up to 22,000 min-¹ (MicroCen MR)
- Great flexibility thanks to different rotor variants, e.g. angled and swing-out rotors
- User-friendly control via touchscreen display with intuitive menu navigation
- Maintenance-free, brushless induction motors (direct drive) for long-lasting operation
- Compact design with stainless steel chamber and armor reinforcement for high safety
Both models support a wide range of applications in microbiological, pharmaceutical and chemical research. Despite different cooling concepts, they can be used in almost identical performance ranges and offer similarly clear menu navigation.

While the uncooled version is primarily designed for routine examinations and continuous use at ambient temperature, the MR model offers an extended temperature range from -20 °C to +40 °C. Fast pre-cooling and cooling at standstill ensure constant temperature control for temperature-sensitive samples. Both variants feature the APRI system, an automatic positive rotor identification, and offer nine-stage adjustable acceleration and deceleration ramps to ensure reliable and reproducible results.
Safety and certifications
The centrifuges are equipped with a motor-controlled lid lock and an emergency release mechanism to prevent unauthorized opening. Unbalance detection including automatic shut-off, multiple integrated lid safety devices and an overspeed protection ensure maximum operational safety. In addition, a stainless steel chamber with armor reinforcement ensures maximum stability even at high speeds. Both models operate in accordance with the applicable CE directives. Integrated overtemperature protection protects against overheating, especially in the cooled MR device.
Practical application scenarios
-
DNA and RNA extraction: The high speed and precise temperature control (MicroCen MR) enable gentle yet efficient preparation of sensitive samples, e.g. for virus RNA isolation.
-
Protein extraction: Especially in biochemistry, users benefit from the variable rotor steps and flexible programming to sediment proteins gently.
-
-
Clinical diagnostics: blood samples can be quickly separated and further processed using microhaematocrit rotors.
-
-
High-throughput screening in pharmaceutical laboratories: The capacity of up to 30 x 2.2 ml reaction tubes enables efficient processing of many samples in a short time.

FAQs
How do I switch between different rotor types?
The centrifuges have a self-centring system which, in combination with the APRI system, enables automatic rotor detection. The rotor is simply placed in the centrifuge chamber and fixed at the mounting points.
How do different sample densities affect centrifugation?
Both models have an automatic speed reduction as soon as a density of over 1.2 g/cm³ is specified. This ensures safe operation.
Can the temperature also be kept constant during standstill?
Yes, the MicroCen MR has integrated cooling during standstill. This means that temperature-sensitive samples remain safely cooled even between individual centrifugation runs.
What maintenance measures are required
Thanks to the brushless induction motors, the devices are virtually maintenance-free. Cleaning work is limited to the stainless steel unit and the outer surfaces in accordance with standard laboratory guidelines.
Summary
The microliter centrifuges presented here combine high speeds, a wide range of rotor options, intuitive operation and reliable safety systems. The robust design and flexible programming enable efficient, precise sample processing in all areas of laboratory research and analysis. In addition to the uncooled model, the cooled version supports a wide range of applications with temperature-sensitive samples. Both solutions offer an ideal combination of ease of use, high performance and durability for demanding users.
