Voorbeeldzinnen

1. Tom put a piece of dry ice into a cup of water.
2. a trap, using liquefied nitrogen or dry ice.
3. Freezing mixture consisting of ethanol and dry ice (temperature –60 °C).
4. The sample can be cooled with liquid nitrogen or dry ice, but care should be taken to avoid condensation of air or pump-fluid.
5. 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.
6. 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.
7. 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.’
8. 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.
9. If rapid transport within 48 hours to the laboratory (in transport medium at 4 °C) is not guaranteed, samples shall be stored and then transported in dry ice at minus 70 °C (temperatures between 4 °C and – 70 °C are advisable only for very short time storage but should be avoided as much as possible).
