24 terms, explained briefly.

European agreement on the carriage of dangerous goods by road. In our range, all vessels up to 10 litres and the T models are approved under ADR.

Cylindrical holder inside the vessel. Short canisters are primarily intended for straw storage, while long canisters each hold two goblets and are suitable for both straws and cryovials.

Box for storing cryovials, placed in racks. Among the vessels, rack systems are only available in the -B versions of the AC 2XL and AC 3XL series (including AC 2XL50T-B), as well as a rack storage system for the AC BIO 430, AC BIO 860 and AC SYS 480 with frame freezers, and for the AC DS10-B, DS15-B and DS25-B dry shippers.

Preserving cells, tissue or other biological material at very low temperatures, typically in liquid nitrogen at −196 °C.

Small screw-cap tube for samples, typically 1–5 ml. Stored in canisters or in cryoboxes on racks.

Vacuum-insulated vessel for storing cryogenic liquids such as liquid nitrogen.

Transport vessel in which an absorbent material binds the liquid nitrogen. Spill-proof. Under IATA the dry shipper is not classified as dangerous goods, because there is no free liquid nitrogen in the vessel.

Daily loss of liquid nitrogen at rest, in litres per day. The largest item in the running costs of a vessel.

How long a vessel holds its temperature without refilling. Roughly capacity divided by evaporation rate — plan with a reserve.

Pressure vessel for storing and dispensing liquid nitrogen, with liquid or gaseous withdrawal.

Liquid nitrogen. Boils at −196 °C at atmospheric pressure.

EU Medical Device Regulation 2017/745.

Larger on-site tank for supplying liquid nitrogen to several consumers.

Diameter of the vessel opening. Narrow neck openings hold the cold longest.

Pressure Equipment Directive 2014/68/EU.

Prevents uncontrolled splashing when dispensing liquid nitrogen by separating the liquid from the gas.

Personal protective equipment for handling cryogenic liquids: cryogenic gloves, face protection, aprons.

Frame that holds cryoboxes inside the vessel. Among the vessels, rack systems are only available in the -B versions of the AC 2XL and AC 3XL series (including AC 2XL50T-B), as well as a rack storage system for the AC BIO 430, AC BIO 860 and AC SYS 480 with frame freezers, and for the AC DS10-B, DS15-B and DS25-B dry shippers.

Thin tube (0.25 or 0.5 ml) for storing semen and embryos, typically in canisters.

Multi-layer reflective insulation inside the vacuum space that keeps radiant heat out.

Transportable Pressure Equipment Directive 2010/35/EU.

German technical inspection body. Five-year interval including TÜV — by us or a licensed regional partner.

High vacuum between inner and outer vessel. It almost entirely stops heat conduction. Auguste Cryogenics gives a five-year warranty on it.

Storage in the cold nitrogen vapour above the liquid, instead of submerged in it.
