Chemical manufacturing

With more than 40 years of experience in API manufacturing, we offer our chemical manufacturing services to third parties.

Our chemical facilities include an Extraction Plant, three Chemical Synthesis Plants, Clean Rooms, product and reagent storage.

We carry out physical treatment of raw materials to optimise extraction, chemical synthesis processes, purification, grinding, drying and packaging, as well as API storage and analysis.

We analyse your production processes and offer you solutions to optimise your manufacturing.

Chemical manufacturing facilities

Extraction plant

A chemical extraction plant is a place where extraction processes are carried out to obtain chemicals of natural or synthetic origin. At Covex, we use our chemical extraction plant, which has been in operation for over 40 years, to manufacture our high quality pharmaceutical and chemical products.

We use a variety of techniques and processes to obtain the active ingredients and chemicals we need for our products. Some of these techniques include distillation, membrane separation, chromatography and solvent extraction.

In addition, our chemical extraction plant has modern facilities and advanced equipment that allow us to control and optimise every stage of the extraction process. This allows us to guarantee the quality and purity of every chemical we produce.

It meets the highest standards of quality and safety, and we are committed to ensuring that each of our products complies with all industry regulations and standards.

Synthesis plants

Covex has three state-of-the-art chemical synthesis plants. The last of these plants was built in 2000 with an investment of 6 million euros, which allows us to offer high quality chemical manufacturing services and advanced technology.


A chemical synthesis plant is an industrial complex designed for the large-scale production of chemical substances. These plants are equipped with advanced machinery and technology to carry out complex chemical processes, which enable the synthesis of chemical compounds of high purity and quality.


At Covex, our chemical synthesis plants have a wide variety of state-of-the-art equipment and technology that allows us to produce a wide range of chemicals, including compounds required for the manufacture of pharmaceuticals.


In addition, we have a team of highly trained professionals in the area of chemistry and chemical engineering, who are responsible for supervising and carrying out each of the chemical manufacturing processes in our plant.

Reagents and chemicals storage

At Covex we have a warehouse specially designed to guarantee the safety and quality of the products we store.


Our warehouse is equipped with advanced safety and temperature control systems, which guarantee the integrity of the stored products. In this way, we can ensure that chemicals and reagents maintain their properties and characteristics throughout the storage period.


Another important aspect of our warehouse is its ability to adapt to the specific needs of each of our customers. We offer a wide variety of storage options, allowing us to store products with different characteristics and requirements.
