Sigma centrifuges from Germany: Product selection

Not all centrifuges are the same: in order to be able to meet the requirements of 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 will find representatives of the following categories:


The Sigma Microcentrifuge 1-14 combines the highest technical requirements with a space-saving design. This allows it to 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, for example, the model 2-6. In addition to ten programmes 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, including the powerful Model 6-16KS. The combination of an angular and swing-out rotor in conjunction with 60 supported programmes and reliable cooling enables many individual applications.

Heated or heatable table-top cooling centrifuges

For versatile rotor configurations and demanding cell culture applications as well as applications in 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 and impress with their high capacity, smooth running and 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? 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 areas of application to be covered. At the same time, the device delivers exact separation results and is suitable for vessels between 0.2 and 1,000 ml. A total of 12 angular and six swing-out rotors are available with this Sigma centrifuge.

Universal benchtop centrifuges

Sigma's universal benchtop centrifuges are also characterised by their high versatility, outstanding reliability and modern user interface, as well as their 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

The Sigma centrifuge 2-16KL is also easy to operate and universally suitable for refrigerated laboratory applications. Thanks to its compact design, it fits into any laboratory. Nevertheless, it has a high capacity of 4 x 100 ml in the swing-out rotor or 6 x 50 ml in the angle rotor, so that there is sufficient space for every task. The cooling 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, including the 4-16S and 4-5L models. While the former is one of the most versatile 3-litre centrifuges on the market, the latter is suitable for particularly high capacities. Added to this are short acceleration times, high torque and 50 programme 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 regarded as 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 laboratory centrifuges require alphanumeric input of programme names, which increases process safety. In addition, the integrated safety system provides temperature deviation monitoring, an acoustic signal, a visual standstill indicator, monitoring of the 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 has been reached, but also allows continuous monitoring. In this way, progress is displayed at all times and facilitates process planning.
  • Innovative microprocessor control: The Sigma centrifuges are equipped with the patented 1-button control Spincontrol S, which is controlled via an innovative microprocessor. This makes it possible to optimally combine 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 programme memory locations: So that your Sigma centrifuge knows exactly which settings are necessary for which work step, numerous programmes can be stored via the TFT display. Depending on the model, up to 60 memory locations are available.
