Life Sciences

Chemteq manufactures wide variety of devices serving life sciences around the globe. We manufacture 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 for:

  • Total Organic Vapors TOV), 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). The indicator does not respond to basic organic vapors or aldehydes, please read manual before using.
  • Ally Bromide
  • Formaldehyde
  • Glutaraldehyde
  • Pyridine & Basic Organic Vapors

We also manufacture filter change indicator stickers for ductless hood filters (BTIS), these BTIS are available for Acids, Allyl bromide, Ammonia, Ammonia & hydrogen sulfide, Aromatic diisocyanates, Basic vapors, Chlorine dioxide, Formaldehyde, Glutaraldehyde, Halogens, Mercury & Mercury II Compounds, Hydrazines, Hydrocarbons, Hydrogen sulfide, Hydrogen sulfide (waterproof), Mercaptans, Methyl ketones, Nitrogen dioxide, Sulfur dioxide and Organic vapors
