Accessories for Exposure Systems
VITROCELL®Vacuum Flow Calibration
Vacuum flow adjustment for aerosol delivery to cell cultures
The VITROCELL® flow calibration valves regulate the flow of the aerosol through the modules in the ml range.
The valves are located between the vacuum pump and the aerosol exposure top. Mass flow meters enable accurate valve read-outs. The consistent and adjustable flow rate ranges from 0…20 ml/min. Alternative flow rate ranges are available upon request.
The valves enable fast control of the flow rates prior to the experiment. They are manufactured from Teflon/stainless steel and can be easily cleaned. If the aerosol contains particles, we recommend installing disposable microfiber filters in front of the valves.
VITROCELL®Mass Flow Meters
For clean and dilution air flow measurement
Mass flow meters are required to adjust the vacuum flow by means of vacuum calibration valves and to accurately set dilution and aerosol generator air flows.
They are available in ml/min to l/min. ranges.
VITROCELL®Mass Flow Controller
Specifically designed to precisely regulate dilution and aerosol generator airflow.
Mass Flow Controller are available for various ml/min ranges.

VITROCELL®Clean Air Purification Station
Filter system to improve the quality of compressed air
The VITROCELL® Clean Air Purification Station is recommended when the air quality of a central air supply system or of a lab compressor contains oil or particles which may influence the test results.
An indication of impurities in the system and thus the need for an improvement of the air quality is evident if the cell viability drops substantially in the clean air exposure modules.

VITROCELL®EPITHELIX Nanopress
For application of powders to 3D cells
An efficient tool for the powder dosing of 3-D cell cultures.
The VITROCELL® EPITHELIX Nanopress enables particle and powder dosage in a precise and reproducible manner, thus making it an optimal tool for exposure to 3-D cell cultures.
The process was developed by EPITHELIX.
First, the test substance is mixed with Dextran powder. The mixing ratio can be varied according to the required dose/response relationship. Using the nanopress, tablets are produced so that they can be placed directly on the cell cultures. After incubation of approximately 15 min. the Dextran tablet dissolves and the cells are directly exposed to the test substance.
How the EPITHELIX Nanopress works
1. Add Dextran powder to the Nanopress.
2. Fill the reservoir.
3. Remove surplus powder from the press surface with a cell scraper.
4. Push the lever down.
5. Push the button to expel the tablet.
6. Remove the tablet.
7. Place the tablet on the apical surface.
8. Incubate for approx. 15 minutes.
9. The Dextran tablet is entirely dissolved.

VITROCELL® Leak Tester
For 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 of the aerosol exposure process.
We recommend to carry out a leak test prior to the experiment and as part of the celaning or service routine.
The respective leakage rate is expressed in mm/60 s of fluid drop in the test column. If the instrument is connected to a closed system, this rate determines the amount of air entering the system from the outside as induces by a leak.
Features
-
Easy and sensitive method
-
Applicable for all aerosol ducts and exposure modules
-
Precise setting on setpoint mark due to bellow with venting valve
-
Solid pod for optimal positioning
