CULTEX^® Exposure Modules

Basic module

The individual basic modules are made entirely of autoclavable material (borosilicate glass, polished stainless steel) housing three wells for three individual cell culture inserts, which are insulated against the inner space of the modules. These vessels are filled with medium individually or from a central inlet, thus providing humidification and nutrification of cells, and creating an optimised microclimate above the cultivated cells. The constant temperature of the unit is assured by a regulated flow of temperate water through the module controlled by an external water bath. The unit has a central water inlet, which is connected via silicon tubes to the water bath. The water flows into the module, filling the chamber up to the top of an outlet at the upper edge of the inner space of the module (overflow principle).

Aerosol exposure top

The exposure top fits tightly onto the basic module via special sealing rings and a special locking device. Each insert vessel is supplied individually with the atmosphere via a funnel-shaped metal inlet tube, guiding the aerosol directly to the biological test organism. Evacuation takes place through a ring of small nozzles around the inlet. The aerosol inlets are connected to the aerosol generation/dilution system and the outlets to the vacuum pump.

The exposure top also has in-/outlets for the heating water circuit in order to avoid condensation.
