Voorbeeldzinnen

1. Tom put a piece of dry ice into a cup of water.
2. Dry ice (solid form)
3. pure CO2 used as dry ice for cooling purposes,
4. a trap, using liquefied nitrogen or dry ice.
5. If required, either dry ice or wet ice must be placed outside the secondary packaging.
6. Freezing mixture consisting of ethanol and dry ice (temperature –60 °C).
7. Solid (dry ice) forms usually contain added substances, such as propylene glycol or mineral oil, as binders
8. pure CO2 used for the carbonation of beverages, pure CO2 used as dry ice for cooling purposes,
9. Commercial carbon dioxide is shipped and handled as a liquid in pressurised cylinders or bulk storage systems, or in compressed solid blocks of ‘dry ice’.
10. The sample can be cooled with liquid nitrogen or dry ice, but care should be taken to avoid condensation of air or pump-fluid.
11. If using dry ice the packaging must permit the release of carbon dioxide gas and not allow a build-up of pressure that could rupture the packaging.
12. If rapid transport within 24 hours to the laboratory is not guaranteed, the samples must be immediately frozen, stored and then transported on dry ice.
13. If rapid transport within 48 hours to the laboratory (in transport medium at 4° Celsius) is not guaranteed, samples shall be stored and then transported in dry ice at – 70° Celsius.
14. If rapid transport within 48 hours to the laboratory (in transport medium at 4° Celsius) is not guaranteed, samples shall be immediately frozen, stored and then transported on dry ice.
15. If rapid transport within 48 hours to the laboratory (in transport medium at 4 °Celsius) is not guaranteed, samples shall be stored and then transported in dry ice at – 70 °Celsius.’
