You cannot store dry ice as it is -80 degrees, therefore it will disappear even if stored in a freezer. You need to obtain it or have it delivered close to the time it will be used.
The only way of storing it effectively is by use of an insulated container with a lid – you should also pack any remaining space in the container with wadded newspaper in order to decrease the oxygen content. Basically you are trying to ‘suffocate’ the dry ice in order to keep it in a solid form for as long as possible. You would still lose in excess of 50% over a 24 hour period.
Dry Ice is supplied in individually wrapped 1kg slices, or you can request that we crush it into pellets for you although when ordering pellets you will lose a small amount due to exposure to the atmosphere during the crushing process.
It is quite impossible to advice on how to use dry ice and the quantity that you will need, as it is not an exact science. You really need to experiment with it personally.
Water temperature affects the characteristics of the fog created. Hotter water or steam vaporizes the carbon dioxide more quickly, yielding lots of fog and using up the dry ice more quickly. If fresh hot water or steam isn't added, the remaining water will cool quickly.
Dry ice increases the level of carbon dioxide in the air where it is used. This can present a respiratory hazard low to ground (or downstairs, if applicable), in enclosed spaces, or with large quantities of dry ice. Do not transport dry ice in the passenger compartment of your vehicle; it must only be placed in the boot of the vehicle.
Orders for dry ice generally need to be placed at least one day before delivery, as it will not be loaded onto the van unless it has been ordered in advance. |
