Empowering Discovery Through
Advanced Laboratory Technologies

The innovative Sigma 4-5KRL is specifically designed for integration into laboratory automation systems (total lab automation). This refrigerated centrifuge enables robot controlled loading / unloading of samples and moreover, can be control via the integrated serial interface. It is ideal for a very high capacity of tubes for clinical in vitro diagnostics (IVD) and for use with microtiter plates and customer specific tubes and bottles. Its compact construction facilitates easy integration into workflows, thereby making a significant contribution to higher efficiency the lab. Based on Sigma’s many years of experience with centrifuges suitable for robot operation, the Sigma 4-5KRL boasts noteworthy innovations and advanced features. The patented bucket lifting device is one of its unique features. This innovative bucket levelling function ensures that after each centrifugation run, the buckets return to horizontally and vertically reproducible positions at the loading / unloading port. This innovation makes a decisive contribution to boosting process reliability.

Consistent minimisation of non-productive process time enables very high throughput, which is increasingly important in clinical chemistry and haematology. The universally deployable Sigma 4-5KRL is also widely used in research labs for biotechnology and pharmaceuticals.
