The new VITROCELL® Millicell Holder

How to use Millicell 24-well Standing Inserts in the VITROCELL® 12 Module Series

The revolutionary new holder system enables for the use of standing inserts in all modules of the VITROCELL® 12 Series for 12-well sized inserts. As an additional advantage, the media com­partment is sealed towards the aerosol exposure head to avoid contact of the test substance with the cell culture media.

Vitrocell® Leak Tester

Must-have device for aerosol research – easy and efficient leak detection

Regular leak tests are mandatory in aerosol research. A leak caused by a forgotten connection or defective o-ring may have a significant influence on the aerosol exposure process. We recommend to carry out a leak test prior to the experiment and as part of cleaning or service routine.

KIT, together with VITROCELL SYSTEMS, set up a first Automated Exposure Station, which has been used for the assessment of nanoscale particle emissions from combustion sources such as ship diesel and wood burners. The system was further developed and offers a compact solution for toxicity testing of nanoparticle (NP) aerosols including sample conditioning, reproducible deposition, integrated dose determination by a quartz crystal microbalance (QCM), flow control, automated processes and data acquisition. The device was also tested with partner laboratories with the aim of potentially standardizing and achieving regulatory acceptance of the method.

VITROCELL® 12/12 now available with Climatic Chamber

For reliable aerosol exposure of cell cultures using 12- or 24-well sized inserts

The VITROCELL® 12/12 module system has been designed to facilitate the exposure of mammalian cell cultures to airborne substances such as gases, complex mixtures, nanoparticles and fibers. It features a throughput of 3 dilution steps @ 3 replicates and 1 clean air control at 3 replicates. In order to optimize the exposure for liquid aerosols and to maximize the performance of humidified air supply it is now also available in a user-friendly climatic chamber.

ALI systems are considered to be a promising exposure system to study toxicological e ects of airborne nanomaterials instead of in vivo inhalation studies and have been widely used to assess the toxicology of nanomaterials in recent years. However, the robustness of these methods is not yet wellunderstood. Here we reported a C&E analysis of a commonly used flow through ALI exposure system.

Benzene and toluene are solvents largely used in industries and emitted into the atmosphere, despite major and direct impacts on human health. This study shows the feasibility of observing mechanisms of toxic action during repeated exposure at ALI to doses close to human exposure. The second strength of this study was the measure of XME induction level with the initiation of several xenobiotic metabolism pathways over time. BEAS-2B cells were exposed to benzene, toluene, m-xylene, or mesitylene gaseous stream diluted in air using the Vitrocell ALI system.

New Video: VITROCELL Cloud Alpha – for Aerosol Research and Cell Exposure at the Air/Liquid Interface (ALI)

Cell exposure system for virus research, testing of inhaled drugs, chemicals and nanoparticles at the Air/Liquid Interface (ALI).

The VITROCELL® Cloud Alpha series is our newest innovation and presents a great leap forward in automated exposure of cell cultures. It combines reliable exposure of cell cultures from the respiratory tract with ease of use. This series is our new take on the well-known and frequently published VITROCELL® Cloud systems (6-, 12- and 24-well). Its functionality enables fully automated processes with an all-in-one control unit. Everyday experiments at the air/liquid interface have never been easier. The Cloud system is suitable for nebulization of solutions and suspensions. Possible fields of application are screening of inhaled drugs, virus research toxicity testing of inhaled substances such as chemicals or nanoparticles.

In response to the scientific need to expose in physiologically relevant conditions, the VITROCELL® Cloud Alpha exposure devices have been specifically designed to enable direct exposure of mammalian cells or tissue at the Air/Liquid Interface. Here the cell cultures are not covered with media as opposed to submerged conditions which cause an undesired inter­action of the formerly airborne substances with the culture media.

The video explains the procedures of the experiment.
