Our Heritage


The story of pK Chemicals goes back more than 70 years. It all began during World War II with two Swedish Nobel Prize-winners, Professor Theodor Svedberg and Arne Tiselius, who initiated basic research at the University of Uppsala based on sugar beets. In 1941 two of their students, Bjørn Ingelman and Anders Grönwall, identified and separated Dextrose and in coorperation with the professors developed Dextran for use in freeze-drying of blood plasma for military medicine. The scientists discovered that Dextran could be used as a replacement for blood plasma during blood transfusions. The scientists contacted Pharmacia, which was one of the oldest independent pharmaceutical companies in Scandinavia, founded in 1911 in Stockholm.


Based upon the scientists' findings Pharmacia launched Macrodex® in 1947. In 1959 a cross-linked dextran, Sephadex, was added to the product range and shortly after Rheomacrodex® was launched in 1961. Pharmacia became one of the first companies in the world to produce a wide range of pharmaceutical products based upon Dextran and subsequently developed into a global company.


Pharmacia Denmark was established in 1964 as Pharmacia´s production plant for Pharmacia´s active products, based upon biotechnology including enzymes for human insulin and for treatment of chronic wounds as well as Iron Dextran for Imferon.


The plant has been producing DEAE-Dextran and Dextran Sulfate since 1981.


The plant has changed name twice; initially to Pharmacia Køge Chemicals in 1991 and since shortened to pK Chemicals in 1998.


In 1997 Pharmacia Køge Chemicals was transferred to Amersham Pharmacia Biotech with its head office in Uppsala, Sweden.


A private investor group acquired pK Chemicals from Amersham Pharmacia Biotech.


In 2003 we acquired the product rights for DEAE-Dextran and Dextran Sulfate from Amersham Biosciences.


In 2005 we acquired the CM-Dextran from GE Healthcare Protein Separations.


In 2010 we acquired the facilities in Hårlev and started the installation of equipment for Dextran production.


pK Chemicals changed owners in 2013 to the present private owner group. Our heritage from Pharmacia in Sweden is up to this day still reflected through the “p” in our company name, but most importantly our roots are reflected in our dedication to manufacture Dextran and Dextran Derivatives, symbolized by the sugar beet in our logo.

Mission and Vision

Our Mission

Our Vision

In a world of ever-increasing quality and documentation requirements for pharmaceutical products our goal is to be our customers´ most trustworthy supplier.
In pK Chemicals we build trust by ensuring: the highest product quality standards in the market; the necessary quality assurance and documentation; and an extraordinary openness about our manufacturing.

Our Logo


Our logo reflects the origin of our business in 1941 where scientists through basic research transformed sugar beets into ingredients for medicine.

In consequence, the Sugar Beet appears in our logo in a clear and simplified form. The logo is designed to make your eyes complete the Sugar Beet form. The form itself is transparent, only visible when surrounded by the cone, which reflects the technical processes in our company. It is an abstract vision of the sugar beet, our very processes and outcome.

Water is an important ingredient in the refining process and is represented by the color blue in a likewise clear style. The blue color highlights pK Chemicals as a transparent and serious business partner within the pharmaceutical and cosmetics industries.

The combined simplicity of the logo reflects the Nordic heritage.

Our Manufacturing Facilities

We have two manufacturing plants, one in Køge and one in Hårlev. Our headquarters is located in connection with our Køge site. 

Køge site
In our facilities in Køge we manufacture Dextran Derivatives as well as contract manufacture ingredients and intermediates according to customers´ requirements.

The plant is situated in Køge approximately 30 km south of Copenhagen. This plant has manufactured active ingredients, Dextran Derivatives as well as intermediates for contract manufacturing customers since 1964. Today most of the equipment is dedicated to cGMP production and enables manufacturing according to cGMP regulations.

Hårlev site 
Our new manufacturing plant for Dextran is located 15 km south of Køge in Hårlev. Since 2015 we have manufactured Dextran for our own Dextran Derivatives as well as for customers.

By acquiring our plant in Hårlev in 2010 we have secured sufficient space for enlarging our capacity considerably as well as possibilities for adding new business areas and contract manufacturing. The buildings were originally built for medical device production, thus being a modern state-of-the-art building, born with all the necessary facilities for high-quality production. The plant manufactures according to cGMP regulations.
