Breakthrough Indicators for Low-Flow Filters (BTI LFF)

Chemteq filter change indicator for low-flow filters (BTI LFF). The BTI LFF are suitable for High Pressure Liquid Chromatography (hplc) waste container filters. the BTI LFF are available Acetone, Acetonitrile, Acids (i.e. Acetic acid, Hydrochloric acid, Trifloroacetic 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 dichloromethane (methylene chloride), Ethanol, Ethyl Acetate, Ethyl acrylate, Ethyl ether, Gasoline, HFIP (Hexafluoroisopropanol), Methanol, Methyl acrylate, Naphtha, Phenol, Sulfolane, and THF (Tetrahydrofuran), Ally Bromide, Formaldehyde, Glutaraldehyde and Pyridine & Basic Organic Vapors.

How Does the BTI LFF Works?

When filter becomes consumed and exhausted, toxic gases and vapors breakthrough it. The contaminated air then enters the BTI LFF and chemically reacts with the indicating sensor producing vivid color change, alerting the user to change the filter. The sorption media on top of the BTI LFF traps traces of contaminants from escaping to the outside environment. The sorption media trap also protects the colorimetric indicator from changing color due to exposure to contaminants in the surrounding environment. This ensures that BTI LFF changes color only when filter is exhausted irrespective of the outside environment.

The Breakthrough Indicator for low-flow filters (BTI LFF) are suitable for High Pressure Liquid Chromatography (hplc) waste container filters.

The BTI LFF are available for:

  • Organic Vapors, including Acetone, Acetonitrile, Acids (i.e. Acetic acid, Hydrochloric acid, Trifloroacetic 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 dichloromethane (methylene chloride), Ethanol, Ethyl Acetate, Ethyl acrylate, Ethyl ether, Gasoline, HFIP (Hexafluoroisopropanol), Methanol, Methyl acrylate, Naphtha, Phenol, Sulfolane, and THF (Tetrahydrofuran). The indicator does not respond to basic organic vapors or aldehydes, please read manual before using.
  • Selected Organic Vapors (SOV) for common hplc applications, including Acetone, Acetonitrile, Acids (i.e., Acetic acid, Hydrochloric acid, Trifloroacetic acid Trichloroacetic Acid), Acrylonitrile, Chlorinated hydrocarbons (i.e. carbon tetrachloride, chloroform and dichloromethane (methylene chloride), Ethanol, Ethyl Acetate, Ethyl acrylate, Ethyl ether, HFIP (Hexafluoroisopropanol), Methanol, Methyl acrylate, Phenol, Sulfolane, and THF (Tetrahydrofuran).
