The carbon filters provide a high-value low cost alternative to original manufacturer equipment filters used on many histology laboratory instruments. The cartridges contain a high grade activated carbon which will absorb most organic and inorganic vapors including xylene, toluene methanol, neutral buffered formalin 10%, isopropyl alcohol and industrial denatured alcohol. To ensure air quality in the laboratory is maintained to safe and acceptable standards, it is essential that the carbon filters in equipment using solvents and other potentially harmful products are replaced at the manufacturer’s recommended interval. Failure to do so may result in excessive vapors building up in the laboratory environment. The manufacturer’s recommended intervals are shown opposite.
