Division 2 The following uses of all controlled substances other than hydrochlorofluorocarbons are not considered as essential laboratory and analytical uses:

refrigeration and air-conditioning equipment used in laboratories, including refrigerated laboratory equipment such as ultra-centrifuges;

cleaning, reworking, repair, or rebuilding of electronic components or assemblies;

preservation of publications and archives;

sterilisation of materials in a laboratory;

any use in primary or secondary education;

as components in experimental chemistry kits available to the general public and not intended for use in higher education;

for cleaning or drying purposes, including the removal of grease from glassware and other equipment;

for the determination of hydrocarbons, oils and greases in water, soil, air or waste;

testing of tar in road paving materials;

forensic finger-printing;

testing of organic matter in coal;

as a solvent in the determination of cyanocobalamin (Vitamin B12) and bromine index;

in methods that use the selective solubility in the controlled substance, including the determination of cascarosides, thyroid extracts, and the formation of picrates;

to preconcentrate analytes in chromatographic methods (e.g. high performance liquid chromatography (HPLC), gas chromatography (GC) adsorption chromatography), atomic absorption spectroscopy (AAS), inductively coupled plasma spectroscopy (ICP), X-ray fluorescence analysis;

for the determination of iodine index in fats and oils;

any other laboratory and analytical use for which a technically and economically feasible alternative is available.
