Our Story

Alesco started out of the dream of a researcher and a entrepreneur, who, joining forces and knowledge, bet on the idea and opened the company in 1992.

After 3 years of few sales, when entrepreneurs were about to give up the business, the company was able to close a large order from a renowned institution in Rio de Janeiro. At the time, this request was the gas that was missing so that the members not only did not give up the business, but also, they came to believe even more in the potential of the market.

Since then, year after year, the company devotes much of its revenue to investing in the business itself. With almost 100% vertical production, Alesco has an industrial patio with its own machinery and tools, which guarantee the quality of its products at each stage of production.

All the growth that Alesco has achieved over these 29 years was supported by its clients and partners who also believed in the company and always supported it with ideas and suggestions for improvement. Helping in this way, to strengthen Brazilian industry, science and talent.

Today, the company is National Leader and has equipment installed in important Animal Models Production Centers, Experimental Labs and Research Institutions all over Brazil and abroad.
