Dry ice comes in three forms: blocks, slices and pellets. Each form is suitable for specific needs.
Blocks (10kg): Suitable for freeze branding, industrial usage, shipping, and certain dry ice smoke machines. As a 10kg dry ice block is one solid piece (and therefore has less surface area than 10kg of dry ice pellets or slices), it will last longer than the same weight of slices or pellets. This makes blocks ideal for long-lasting shipping or storage.
Slices (10 x 1kg): Ideal for the storage and/or transportation of perishable goods such as food or medical supplies. Each slice is individually foil-wrapped for ease of use and to help reduce sublimation levels.
Pellets (10kg of 9mm diameter): Ideal for smaller-scale needs. University and hospital laboratories often use dry ice pellets in experiments, small scale storage, and for delivery purposes. Dry ice pellets are ideal to make fog effects for theatrical and entertainment purposes. Commercial businesses often use dry ice pellets for small-scale or one off storage or delivery purposes.
Drice (3mm diameter pellets): Specially designed for use in clean-blasting – not for domestic use.
