NEW: Sigma 4-5KL refrigerated benchtop centrifuge

The powerful Sigma 4-5KL laboratory centrifuge is designed for throughput and capacity.
For all applications where room temperature must be maintained, the Sigma 4-5KL is recommended.

To save energy and costs, the refrigerated centrifuge has the ECO mode feature. After an individually adjustable time, the centrifuge automatically switches to standby mode when not in use. This is not only energy-efficient but also improves the working atmosphere in the laboratory by significantly reducing the noise level by switching off the cooling. 

Long-term safe operation with Sigma Comfort coating

Thanks to the new Sigma Comfort coating, Sigma Comfort rotors no longer need to be greased. The rotor and buckets will comfortably operate together for several years – with no need for regular greasing. For typical applications in normal labs, the Sigma Comfort coating will last for up to 5 years.

Sigma 1-7: Powerhouse for a small volume of samples

Small, quiet and powerful – those are the hallmarks of the Sigma 1-7. This new small centrifuge is excellently suited to the separation of up to 6 blood or urine samples. The compact size makes it ideal for medical practices, veterinarians and small laboratories. It can also be put to good use for environmental analysis and in various educational institutions, such as schools or universities.

The laboratory centrifuge Sigma 1-7 features a high RCF level of up to 6.153 x g as well as sturdy, high-quality finishing.

Top marks for functionality

The Sigma 2-7 arose from the experiences and desires of our customers. The technical features of this centrifuge are impressive: stainless steel bowl, imbalance switch, motorised lid lock, innovative run display with blue LEDs, and process reliability. The centrifuge is also very quiet in operation. Specimens are only slightly warmed, which is important for blood specimen tubes in particular. Together with a versatile, modular swing-out rotor, the foundation is laid for a successful career in many laboratories.

Sigma 4-5KRL

The refrigerated centrifuge Sigma 4-5KRL has specifically been developed for system integration and can be easily integrated into any workflow. Thanks to a lid opening time of only 3 seconds and high-precision positioning of rotor and buckets, this particularly smooth centrifuge is a reliable tool offering 24/7 availability. 

This robust device is very undemanding and gets by with only one service interval per year. Tubes, for which Sigma manufactures customized adapters upon request, as well as microtiter plates can be centrifuged with the Sigma 4-5KRL.
