Emission Reduction
Use Vaplock exhaust filters to mitigate health hazards and reduce harmful chemical emissions and odors from laboratory solvent containers. Developed and tested specifically for HPLC organic solvents, they may be used in conjunction with Vaplock breakthrough color indicators to determine longevity and establish a replacement schedule.

Adaptable Design
Available in 75g and 300g cartridge sizes, Vaplock filters include activated media for organic solvents and are constructed of an HDPE housing with 1/4” NPT female receiving port. Attachto various point emission sources with Vaplock Filter Adapters. Please inquire for other sizes and formats.

Colorimetric Change
Designed to detect the end-of-service life for Vaplock exhaust filters, breakthrough indicators respond under exposure to organic solvent vapors. Final effects display within minutes or hours of exposure. Color saturation varies by solvent. Replace the exhaust filter when a variation occurs. Housing is acrylic, with borosilicate glass option available.

Multiple Solvent Detection
Breakthrough Indicators may be used with the following chemicals. This list is not comprehensive. Please inquire for detection of other organic solvents: Acetone, Acetonitrile, Acids (i.e. Acetic Acid, Hydrochloric Acid, Trifl oroacetic Acid, Trichloroacetic Acid), Acrylonitrile, Aliphatic hydrocarbons (i.e. Hexane), Aromatic Hydrocarbons (i.e. Benzene, Toluene and Xylenes), Chlorinated hydrocarbons (i.e. Carbon Tetrachloride, Chloroform and Methylene Chloride), Ethanol, Ethyl Acetate, Ethyl Acrylate, Ethyl Ether, Gasoline, HFIP (Hexafluoroisopropanol), Methanol, Methyl Acrylate, Naphtha, Phenol, Sulfolane, THF (Tetrahydrofuran).

Product Usage
Not for use in the presence of basic vapors in high concentrations (i.e. Pyridine and aliphatic amines), which impair performance of the indicator. Does not respond to gaseous aliphatic hydrocarbons or aldehydes. Avoid Exposure to heat or direct sunlight. Use only at room temperature. Shelf life is 12 months. For analytical research purposes only.
