德國Sigma Centrifuges 實驗室離心機 
德國SIGMA實驗室離心機股份有限公司是世界著名的專業實驗室離心機生產廠家之一，由Martin Christ sen于1948年創立，現有職工130余人。其生產的離心機到20世紀60年代已經在世界范圍內銷售，并成為歐洲最大的離心機生產者之一。60年代末Martin Christ sen把離心機部門出售給HERAEUS集團，但保留了研發部門，在此基礎上HERAEUS公司于1970年生產離心機。之后的四五年時間，公司員工請求重新為Martin Christ sen工作。于是Martin Christ sen于1975年重新創辦了離心機部門，取名SIGMA并發展至今。目前，由他的兩個兒子繼續經營公司。大兒子Michael Christ負責離心機部門，即SIGMA，小兒子Martin Christ jun負責凍干機部門，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.
