德国SIGMA实验室离心机股份有限公司是世界著名的专业实验室离心机生产厂家之一，由Martin Christ sen于1948年创立，现有职工130余人。其生产的离心机到20世纪60年代已经在世界范围内销售，并成为欧洲最大的离心机生产者之一。60年代末Martin Christ sen把离心机部门出售给HERAEUS集团，但保留了研发部门，在此基础上HERAEUS公司于1970年生产离心机。之后的四五年时间，公司员工请求重新为Martin Christ sen工作。于是Martin Christ sen于1975年重新创办了离心机部门，取名SIGMA并发展至今。目前，由他的两个儿子继续经营公司。大儿子Michael Christ负责离心机部门，即SIGMA，小儿子Martin Christ jun负责冻干机部门，就是今天的Christ

Sigma Laboratory Centrifuges is a worldwide leading manufacturer of laboratory centrifuges.

Centrifuges are standard equipment in every laboratory and are used intensively to separating components with different densities from liquids, for which they are virtually indispensable. 

Sigma offers a broad spectrum of laboratory centrifuges, fixed-angle and swing-out rotors and accessories. All of our products meet high standards of reliability and safety. The application areas include pharmaceutical research, biotechnology, medical analytics, environmental analytics, petroleum analyses and many other areas. 

Martin Christ Sr started producing centrifuges in 1948. In 1975 he founded the company Sigma Laborzentrifugen. Sigma gained worldwide recognition with a new maintenance-free drive system for laboratory centrifuges, and the company grew rapidly. The company culture of the family-owned business is based on flat organisational structures with short communication paths, sustainable business operations, and close networking with international representatives and dealers. 

Sigma centrifuges are known for their performance and reliability as well as a high standard of safety. Sigma has the right solution for every specific customer need – compact small centrifuges, high-speed or stand-alone centrifuges, refrigerated or unrefrigerated, heated, or especially low noise. We also make special models tailored to individual requirements. Our products are developed by a team of engineers at our Osterode facility, who also support production from start to end.  Our customers additionally benefit from our expert worldwide service.

Sigma Laboratory Centrifuges collaborates closely with our affiliated company Martin Christ Freeze Dryers to share knowledge. This generates large synergies, which benefit both product domains as well as our customers.
