Type of soiling

Identification of the type of soiling is important in the selection of the correct cleaning agent and for optimum arrangement of the cleaning process.

The type of soiling can be divided into three areas:

Organic Substances

Typical organic contamination in the laboratory includes proteins, fats/oils and carbohydrates.

Inorganic Substances

Typical inorganic residues found in the laboratory include e.g. watery solutions of inorganic acids (e.g. hydrochloric acid, sulfuric acid) and alkaline solutions (sodium hydroxide or potassium hydroxide) or salt solutions (sodium chloride, sodium nitrate, iron chloride etc.).

Microbiological Residues

In the microbiological area it is often necessary to remove growth media, nutrient broth and microorganisms from the laboratory glass.
