Value	Code Name	Code	Code System	Code Description
Aerosol Spray	Aerosol Spray Dosage Form	C42889	NCI Thesaurus	An aerosol product which utilizes a compressed gas as the propellant to provide the force necessary to expel the product as a wet spray; it is applicable to solutions of medicinal agents in aqueous solvents.
Cryobath	Cryobath	C63392	NCI Thesaurus	A device designed to generate a liquid environment that is below the freezing point of normal biological tissues (usually -50 to -70 degrees celsius).
Cryostat	Cryostat	C63393	NCI Thesaurus	An instrument designed to cut frozen tissue specimens on the order of micron-scale thickness, generally for the purposes of histolgical evaluation.
Dry Ice	Dry ice	C63373	NCI Thesaurus	A solid form of carbon dioxide used as a refrigerant. At temperatures above -78.5 degrees C and ambient pressure, it changes directly to a gas as it absorbs heat.
Dry Ice / Hydrocarbon Slurry	Dry Ice Hydrocarbon Slurry	C63373:C552:C63391	NCI Thesaurus	A solid form of carbon dioxide used as a refrigerant. At temperatures above -78.5 degrees C and ambient pressure, it changes directly to a gas as it absorbs heat.: A group of organic compounds that consist of only hydrogen (H) and carbon (C) atoms and are involved in energy production. They may be cyclic or non-cyclic compounds. They may have double bonds, single bonds or both with carbon forming the backbone.: A mixture of solid and liquid matter phases.
Liquid Nitrogen	Liquid nitrogen	C45298:C61863	NCI Thesaurus	A substance in the fluid state of matter having no fixed shape but a fixed volume.: Nitrogen
Liquid Nitrogen / Isopentane	Liquid Nitrogen Isopentane	C45298:C61863:C63387	NCI Thesaurus	A substance in the fluid state of matter having no fixed shape but a fixed volume.: Nitrogen: An organic, branched-chain alkane with five carbon atoms.
Liquid Nitrogen Vapor	Liquid Nitrogen Vapor	C68796:C63390	NCI Thesaurus	Nitrogen in a liquid state, having been super-cooled to about -200 degrees Celsius.: The gaseous state of matter that is a solid or liquid at normal room temperature.
Not Specified	Unspecified	C38046	NCI Thesaurus	Not stated explicitly or in detail.
