    • Microchem inspected by US FDA

      Microchem is pleased to provide an update on the most recent US regulatory status of its contract micronization facility. On 31 March 2014, an experienced investigator from the US FDA started to conduct a 3-days GMP inspection in Microchem. The inspection has been successfully concluded. No Form 483 was issued.

    • Revamping of the clean rooms

      October 2012 - Microchem, in a perspective of continuous quality improvement, has recently carried out a revamping of the clean rooms upgrading them to the last pharmaceutical standards.


It is a story that started a long time ago, around the mid-sixties, when the micronization of active ingredients in pharmaceuticals was more or less unheard of.

In those days, fluid jet micronization was being used, in practice, more often in other sectors, for example in mineral, herbicide and antiparasitic products.

By following this principle and adapting it over the course of time to the increasing demands of the chemical and pharmaceutical industry, micronization started to take its first steps.

At first, the orders came from small and

medium-sized companies that found it difficult to set up key departments soley for their micronization requirements, but then, in time, the first “blue chips” joined in.

With the consolidation of Microchem in 1978, and also at the Italian level, micronisation became fundamental. At that time Italy was the number one world market for the production of APIs and even today, it remains in third place, headed only by India and China.

Instilled in the company is the DNA of complementary skills held by its founder engineer, Alberto Martinoli: the art of designing and specifying micronization

equipment and machinery and, on the other hand, the art of simply raising service levels to an absolute maximum.

It is quality and service that are the focal points at Microchem: quality assurance, quality controls and careful laboratory analysis constitute the three pillars on which Microchem bases all of its micronization activities.

By service we mean the capacity to adapt the micronization specifications to the needs of the client, the constant presence of our staff and the flexible and dynamic approach that typifies the company culture at Microchem.

Project management

Project Management

This scheme shows how Microchem works with its potential and existing clients. The relational aspect is really important for the company and all its employees.

For us, quality means loyalty: it gives us enormous satisfaction to see how our clientele has remained loyal to us over the years, giving rise to long-lasting relationships and enabling us to create and build new profitability.




Our spiral jet mills have been designed to guarantee precise scalability. This enables the active ingredient to be followed from its first R&D phases through to marketing; it allows us to operate with the same product from batches of 0.2 g up to several tonnes.

Extremely precise PSD

Thanks to our technology we are able to obtain very fine and precise particle size distribution with only a single micronization passage for nearly all pharmaceutical ingredients.


Microchem provides contract micronization of active ingredients for the pharmaceutical industry. Micronization is undertaken using a range of fluid jet mills, conceived and designed by us.

Excellent Yield

We guarantee to reduce the product build-up and to achieve yields higher than 99% for the industrial process, starting from quantities of 1kg

No heat generation

Thanks to the isothermal feature of our jet mills, we can micronize any pharma ingredients, even those with a very low melting point (30-40°C).


Spiral jet mills and a hammer mills can be used successfully not only to reduce the particle size, but also to remove lumps and agglomerates.


Our clean rooms and isolators can be used to dispense and re-pack bulk API into small containers at any amount.
