for 35 mm petri dishes

The VITROCELL® AMES 48 module system has been specifically designed and engineered to facilitate the research of bacteria in direct exposure to airborne substances such as gases, complex mixtures, nanoparticles and fibers.

Only 1 system is required: 7 dilutions with 6 petri dishes for exposure to the substances and 6 Petri dishes in the same system for clean air control.

A complete dose / response profile can be obtained in one experiment. The bacteria are directly exposed using controlled flow rates of the aerosol.

After exposure, the cultures are further processed to measure the number of revertants.

Base module

The base module has been designed for 48 Petri dishes.

The base module is made of aluminum with compartments of stainless steel. It is autoclavable at 121° C (250° F) for 20 min. This module is renowned in scientific circles for its ­reliability and durability.

More about Ames 48

Easy access to all components

Heating System

Heating Systems for base module and climatic chamber to avoid effects of aerosol condensation.

Exposure module with 7th row on drawer

Microbalance Sensor – Additional option

A choice of modules equipped with 1 Quartz Crystal Microbalance for dose monitoring is also available.

Petri dishes

The module has been designed for 35 mm Petri dishes.

Controlled inlet flow

VITROCELL® exposure systems have been specifically designed and engineered to give researchers the possibility of directly exposing mammalian cells or tissue at the air/liquid interface. Thus, all cell types cultivated on microporous membranes can be used. This approach allows for more credible and authentic results than by submerged exposure due to a closer replication of the human physiology.
