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.

Screening antiviraler pharmazeutischer Leitwirkstoffe gegen das Coronavirus (COVID-19 / SARS-CoV-2)

VITROCELL in vitro Expositionssysteme für hocheffiziente und realistische Applikation aerosolisierter Medikamente auf menschliche Zellen des Atemtraktes unter physiologischen Bedingungen.

In der Inhalationstherapie werden pharmazeutische Präparate als Aerosole auf Zellen des Atemtraktes im Nasen- oder Lungenbereich appliziert. Zur präklinischen Entwicklung neuer Arzneimittel werden dafür oft kommerziell erhältliche, physiologisch relevante in vitro Zellkulturmodelle des Nasen-, Rachen- oder Lungenepithels verwendet. In jüngster Zeit wurden diese Modelle verfeinert, um SARS-CoV-2 Infektionen nachzuahmen.

This study was the first to investigate the toxicological effects of well characterized aerosols released during combustion of thermoplastic nanocomposites using an air–liquid interface exposure system. Even though studies on the toxicological potential of combustion-generated particulate matter as well as VOCs have been published, none of them was designed to investigate the effect of the native aerosol using appropriate realistic lung cell culture models. In the current study we investigated the combustion behavior of PE-based nanocomposites on a lab-scale burner. As nanoscaled fillers TiO2 NP, CuO NP, as well as CNT were chosen for this study, with TiO2 NP representing a commonly used insoluble and inert nanomaterial, CuO NP as a known in vitro cyto- as well as genotoxic nanomaterial, and CNT as a fiber-shaped nanomaterial.

This unique experimental “Mini-BACS + AES” setup is able to provide steady conditions to perform in vitro exposure under ALI conditions to aircraft engine oil and hydraulic fluid fumes, generated at respectively 350 ◦C and 200 ◦C. Exposure of the Calu-3 monoculture and Calu-3 + MDM co-culture lung cell models to high levels of aircraft engine oil and hydraulic fluid fumes under ALI conditions can reduce TEER and viabilities of the cells, induce cytotoxicity, and increase production of proinflammatory cytokines. Hydraulic fluid fumes are more toxic than engine oil fumes on the mass concentration of fume basis, which may be related to higher abundance of OPs and smaller particle size of hydraulic fluid fumes. The toxicological data clearly reflect the potential health risks during fume events in aircraft cabins.

Optimal Solution for Everyday Experiments  at the Air/Liquid Interface
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. The series comprises the Cloud Alpha 6, - 12, - 96 and Cloud Alpha MAX – they represent an optimal solution for everyday experiments at the Air/Liquid Interface using 6-well, 12-well, 24-well or 96-sized inserts. We have run extensive tests to ensure the Cloud Alpha series devices match our standards in terms of the established characteristics for Cloud principle exposure devices: Deposition Efficiency, Spatial Deposition and Repeatability.

The present study illustrate a methodological approach which allows comparing, in an original and innovative way, the physical, chemical, and toxicological properties of different fine and ultrafine particles. In this study, two different operating conditions were used to obtain model particles containing either high (CAST3) or low (CAST1) organic contents, and exposed differentiated NHBE cells “on-line” at the air-liquid interface to be closer to realistic conditions.
