Test fluid Topor for analysis of pore size distributions with Pore Size Meter PSM 165
*** Topor will be discontinued on 31.12.2025. If you have any questions, please contact our sales team ( sales@topas-gmbh.de ). ***
Topor is insoluble in water, colorless and odorless liquid which is very well suited as a test fluid to determine the pore size distribution of tissue and porous materials bacause of its low surface tension.
It can be used for studies of porous materials with the pore size analyzer PSM 165. Topor can be supplied in quantities of 500 ml, 1000 ml or 5000 ml.
Fog fluid TopFog Light for operation of the Condensation Fog Generator CFG 291
The fog fluid “TopFog Regular” is a mixture of polyhydric alcohols and water for visualizing airflows. The main application is the flow visualization in cleanrooms in connection with the Condensation Fog Generator CFG 291.
The fog fluid TopFog Regular is non-toxic, sterile, free of oil and grease and evaporates after a sufficient time without leaving any residue. Depending on the application, different fog densities may be required. For the generation of dense fogs, the fog fluid TopFog Regular is particularly suitable.
The generated fog is used for inspections of cleanroom systems in accordance with the standard series ISO 14644 or guideline VDI 2083-3 in order to detect leaks in the transition areas of cleanroom elements, to prove the presence of laminar displacement flow or to visualise the overpressure level of cleanrooms.

The fog fluid TopFog Regular is non-toxic, sterile, free of oil and grease and evaporates after a sufficient time without leaving any residue. Depending on the application, different fog densities may be required. For the generation of more transparent fogs, the fog fluid TopFog Light is recommended.
The generated fog is used for testing of cleanroom environments in accordance with standards or guidelines like ISO 14644 and VDI 2083-3. Possible applications are leak detection in transition areas of cleanrooms, visual detection of low-turbulence air flows or demonstration of overpressure level of cleanrooms.
Fog fluid TopFog for operation of the Condensation Fog Generator CFG 290
The fog fluid “TopFog” is a mixture of polyhydric alcohols and water for visualizing airflows. The main application is the flow visualization in cleanrooms in connection with the Topas product Condensation Fog Generator CFG 290.
This is used to perform a test to determine the supply airflow rate in a non-unidirectional cleanroom and the air velocity distribution in a unidirectional cleanroom according to ISO 14644-3. The product must be used appropriate as delivered.
