SIGMA 1-14 Microcentrifuge
The compact and powerful microcentrifuge for versatile routine and special applications in medical, biotechnological and research-oriented laboratories: The centrifuge described here guarantees high durability, a wide range of rotor options and an ergonomic, user-friendly design. Thanks to its reliable performance and flexible application options, it proves to be the optimal choice when it comes to processing samples efficiently and gently.
Performance features and technical highlights
This state-of-the-art centrifuge is characterised by a special combination of robustness, ease of use and modular accessories. Particularly noteworthy are the maintenance-free drive and low noise levels during operation. Below is a compact overview of some key parameters and equipment details:
- Speed range: 200 to 14,800 rpm
- Maximum capacity: 24 × 2.0 ml
- Various rotor types: Angle rotor, PCR rotor, haematocrit rotor
- Low noise level: Below 60 dB(A)
- Maintenance-free brushless drive
- Certification: Complies with EN 61326 (electromagnetic compatibility)
- Timer adjustable up to 99 min. 59 sec. and continuous operation
In addition, short acceleration and braking times are among the hallmarks of this device. With acceleration times of 13 to 20 seconds, depending on the rotor installed, and braking times of 11 to 14 seconds, rapid process sequences are possible. The compact design (176 × 212 × 266 mm) keeps space requirements to a minimum, which is crucial in many laboratories. Weighing only 6 kg, it is also easy to transport between different departments.
The minimum speed of 200 rpm allows for particularly gentle sedimentation of sensitive cells and samples, while the maximum speed of 14,800 rpm ensures rapid separation of particles, blood components or macromolecules. Another important factor for user comfort is the moderate temperature increase in the rotor chamber, which is kept very low at a maximum of 9°C or 10°C, depending on the rotor type.
Easy operation and high safety
In addition to its wide range of capabilities, the device is extremely intuitive to use: a user-friendly display with clear readouts allows precise entry of speed or RPM, time and optional programmes. The automatic lid opening speeds up the process at the end of the run, while the emergency release provides additional safety for sensitive applications. Certification in accordance with EN 61326 means that the device can be used in a wide range of laboratory environments without the risk of interference from electromagnetic influences.
The robust and maintenance-free drive ensures trouble-free continuous operation without the need for regular motor servicing. All attachments are designed to be stable and durable, which keeps operating costs low in the long term and ensures reliable results with every run.
Specific examples of use
- Separation of blood components: Haematocrit determinations, separation of serum and plasma, or diagnostics in clinical laboratories can be easily accomplished with this microcentrifuge.
- DNA and protein research: The rapid pelletisation of macromolecules makes the device a reliable choice for research projects, such as the purification of DNA and RNA samples.
- Cell culture work: Different volumes of cell enrichments or the separation of cellular components can be carried out efficiently and reproducibly.
- Pharmaceutical analyses: The precise sedimentation of even the smallest active ingredient particles contributes to consistent analysis results and is ideal for quality control processes.
Frequently asked questions
How long does an average centrifugation cycle take?
The duration depends on your individual protocols. However, thanks to the flexibly adjustable timer (up to 99 min 59 sec) and the short acceleration and braking phases, a wide range of programmes can be carried out quickly and accurately.
What safety features are integrated?
The automatic lid opening switches on at the end of the run, and an emergency release is also available. In addition, EN 61326 certification ensures a high level of safety and quality, especially with regard to electromagnetic compatibility.
For which sample vessels is the system suitable?
As standard, 0.2 ml, 0.4 ml, 1.5 ml or 2.0 ml vessels can be used. With the appropriate rotor and adapter, the device can be flexibly adapted to specific laboratory requirements.
How loud is the centrifuge at full capacity?
The device achieves a noise level of less than 60 dB(A) at maximum speed. This keeps the working environment quiet and pleasant, even during intensive continuous use.
Is a regular motor update necessary?
No, the integrated motor is brushless and therefore completely maintenance-free. This reduces downtime and saves maintenance costs in the long term.
