Inhalation

Inhalation

At Vivotecnia, we have extensive experience in inhalation toxicology and efficacy studies in both rodent and non-rodent species, supported by fully integrated, proprietary inhalation technology operated in-house. We are the only CRO worldwide offering this level of dedicated inhalation capability, enabling precise, reproducible and regulatory-compliant studies tailored to the specific properties of each compound and the most demanding international standards.

Preclinical regulatory CRO

Scroll down

Established – 2000

All inhalation studies are conducted in our dedicated, cutting-edge inhalation facility, operated exclusively by a specialized team of inhalation scientists and technicians. Unlike conventional CROs that rely on external systems or standard equipment, Vivotecnia designs, operates and controls its own inhalation exposure technologies, ensuring full oversight of study execution and data quality.

Our facilities and processes ensure full compliance with Good Laboratory Practices (GLP) and the most demanding international standards (OECD, ICH). We operate 7 days a week, 365 days a year, providing unmatched continuity, flexibility and reliability for complex inhalation projects.

Generation of Respirable Atmospheres in Inhalation Studies

At Vivotecnia, we tailor the generation of respirable test atmospheres to the physical characteristics of each compound, ensuring controlled, reproducible, and regulatory-compliant exposure conditions. 

gases

Gases

Homogeneus mixtures are produced using dynamic dilution systems, enabling highly accurate and traceable control of target concentrations.

Liquids

Liquids

Volatile substances and inhalable liquid formulations are transformed into vapors of fine aerosols through advanced nebulization techniques.

Solids

Solids

Dry powders are aerosolized using high-performance dust generators, producing particles within the respirable range (1-5 μm).

Each exposure system is designed to deliver stable, homogeneus, and traceable atmospheres, critical for reliable toxicology studies. 

Unique glass exposure technology

Vivotecnia is the only CRO worldwide equipped with proprietary, custom-designed glass exposure tubes for inhalation studies. This exclusive technology represents a true benchmark in inhalation toxicology and is a key differentiator of our CRO capabilities. These tubes:

This system enables precise and reproducible inhalation exposure – a technological benchmark in the field.
