Sigma centrifuges from Germany: Product selection

Not all centrifuges are the same: In order to be able to meet as many applications as possible, from biotechnology and the pharmaceutical industry to food production and nanotechnology, Sigma Laborzentrifugen GmbH manufactures various devices. The aim is to be able to meet the respective customer requirements and to offer the right centrifuge for every laboratory. In the wide range ofMedSolut you can find representatives of the following categories:


The Sigma Microcentrifuge 1-14 combines the highest technical requirements with a space-saving design. Thus, it can show great performance even in a small space. It combines two angular rotors with a maximum capacity of 24 x 1.5/2.0 ml.

Small centrifuges

For all separation procedures of smaller samples, a Sigma small centrifuge is recommended, which includes the Model 2-6, for example. In addition to ten programs and a lockable control system, the device impresses with an integrated safety system and energy-efficient cooling.

Laboratory tabletop centrifuges

Sigma Laborzentrifugen GmbH also offers a diverse range of benchtop refrigerated centrifuges, which includes the powerful Model 6-16KS. The combination of angular and swing-out rotor in combination with 60 supported programs and reliable cooling enables many individual application purposes.

Heated or heatable table-top cooling centrifuges

For versatile rotor configurations and demanding cell culture applications as well as applications from the field of biotechnology, centrifuges from Sigma that can be both cooled and heated are recommended. The 4-16KHS and 6-16KHS, in particular, fall into this category, offering high capacity, smooth running and a modern user interface.

Microcooling centrifuges

The Sigma 1-14K is a refrigerated microcentrifuge that can also be used as a benchtop centrifuge. It is considered the most compact solution on the market and can easily maintain a temperature of 4 °C - even at maximum speed of 15,000 rpm.

Universal centrifuges

Medical diagnostics, substance separation, routine tests or cosmetological work areas after all? If various applications have to be covered in the laboratory that place different demands on the Sigma centrifuge, the universal centrifuges from this manufacturer are particularly suitable. These include the 2-16P and 3-16L models. Both laboratory centrifuges are true multi-talents and also offer a generous filling volume.

Heated universal centrifuge

The universal Sigma laboratory centrifuges are also available in a heated design and are combined in the 6-16HS model series. This allows even more application areas to be covered. At the same time, the instrument delivers exact separation results and is suitable for tubes between 0.2 and 1,000 ml. A total of 12 angular and six swing-bucket rotors are available with this Sigma centrifuge.

Universal benchtop centrifuges

Sigma's universal benchtop centrifuges are also characterized by high versatility, outstanding reliability and a modern user interface, as well as a compact design. These include, for example, the 6-16S model, which achieves a maximum speed of 12,000 rpm (swing-out rotor) or 13,500 rpm (angle rotor).

Universal cooling centrifuge

Easy operation and universal suitability in refrigerated laboratory applications are also provided by the Sigma Centrifuge 2-16KL, which fits into any laboratory thanks to its compact instrument design. Nevertheless, a high capacity of 4 x 100 ml in the swing-out rotor or 6 x 50 ml in the angle rotor is provided, so that there is sufficient space for every task. The cooling system can be finely adjusted and covers a temperature range between -10 °C and 40 °C.

Laboratory centrifuges with large volumes

Do you work with large samples or have to cover a large throughput? Then the Sigma laboratory centrifuges with large volumes come into play, which include the 4-16S and 4-5L models. While the former is one of the most versatile 3-liter centrifuges on the market, the latter model is suitable for particularly high capacities. It also features short acceleration times, high torque and 50 program memory locations.

The equipment of Sigma laboratory centrifuges

When we talk about Sigma centrifuges, we are talking about powerful, high-quality equipment from a top manufacturer that can be flexibly adapted to your requirements and needs in the laboratory. Sigma Zentrifugen GmbH from Osterode is not only considered the absolute market leader, but also convinces with many technical and innovative unique selling points. The equipment advantages of the devices include the following aspects in particular:

  • Integrated safety system: when handling sensitive samples and substances, safety is at the top of the list. Therefore, Sigma's laboratory centrifuges require alphanumeric input of program names, which increases process safety. In addition, the integrated safety system provides temperature deviation monitoring, an acoustic signal, visual standstill indication, monitoring of rotor cycles run and cycle counting of the centrifuge.
  • Sustainable ventilation: The fan control is regulated depending on the required cooling capacity, so that energy consumption is reduced to a minimum. At the same time, this feature ensures particularly quiet operation.
  • Practical timer: The integrated timer not only indicates when the target speed is reached, but also allows for ongoing monitoring. This means that progress is displayed at all times and facilitates process planning.
  • Innovative microprocessor control: Sigma centrifuges are equipped with the patented 1-button Spincontrol S control system, which is controlled by an innovative microprocessor. This allows an optimal combination of internal quality management and external communication with a LIMS.
  • Low noise level: Not only energy-efficient, but also quiet - this manufacturer's centrifuges impress with low noise levels and quiet operation.
  • Numerous program memory locations: So that your Sigma centrifuge knows exactly which settings are necessary for which work step, numerous programs can be stored via the TFT display. Depending on the model, up to 60 memory locations are available.
