Indicating Silica Gel 25kg can adsorb up to 30% of its own weight in water vapour.
Indicating Silica Gel 500g can adsorb up to 30% of its own weight in water vapour.
Indicating Silica Gel 500g is designed to adsorb moisture in closed spaces such as storage containers, toolboxes, and transformer breathers. It is suitable for protecting electronics, documents, and humidity-sensitive products.
If used for standard moisture absorption, Indicating Silica Gel 500g beads can be disposed of in regular household rubbish. If used for gas separation, they must be taken to an authorised waste disposal facility, where a fee may apply.
Yes, it changes from orange to green or blue to pink upon moisture saturation for real-time monitoring

Yes. Moisture is an important part of the oxygen absorption process, as oxygen absorbers require moisture to activate and react effectively.
For food products with a moisture content above 10%, the moisture level is generally not a concern for the operation of the oxygen absorber. The absorber can use available moisture within the package to support the reaction.
During this process, the oxygen absorber may absorb some moisture from the surrounding package environment while removing oxygen. A small amount of heat may also be generated, which is a normal part of the oxygen absorption reaction.

300cc Oxygen Absorbers trap oxygen. Given that air comprises 20% oxygen and 80% nitrogen, the absorber will only be removing the 20% of the atmosphere that is oxygen. The volume of nitrogen remaining will mean your bag will not deflate to the extent of the bag becoming hard or rigid.
How quickly 300cc Oxygen Absorbers remove oxygen from the atmosphere will depend on the conditions. In dryer climates, it may take up to a week for 300cc Oxygen Absorbers to fully activate. Warmer, humid climates however accelerate the process and may take only 48 hours for the same result.
Store 300cc Oxygen Absorbers at room temperature (5°C to 30°C), away from direct sunlight. They should be stored in their sealed package or a glass jar with a gasketed lid. Select the smallest glass jar possible to minimise the oxygen the absorbers will remove from the jar. 300cc Oxygen Absorbers in a well-sealed container will cause the lid to pop down. The shelf life of a 300cc Oxygen Absorber is up to 18 months.
We understand that Protection Experts Australia customers should feel confident they are receiving the best quality products. The unopened 300cc Oxygen Absorber bag might feel hard, but that is due to the vacuum seal as they are all clumped together. Once the bag is opened, the sachets will separate and should feel like the container sand/granules. All our 300cc Oxygen Absorbers are packaged with a quality check, called the ‘eye’. The indicating eye is packaged with the 300cc Oxygen Absorbers and will appear pink, showing that the package is sealed and oxygen-free. Should the eye appear purple, this indicates that oxygen has penetrated the packaging through possibly a puncture or poor seal and the 300cc Oxygen Absorbers have been compromised. In this instance, we ask that you contact our office immediately so that the problem can be rectified.

300cc Oxygen Absorbers, once exposed to the atmosphere, begin to get to work immediately. That is why we suggest that unused 300cc Oxygen Absorbers should be resealed within 30 minutes to ensure the integrity of the product is maintained.
A new 300cc Oxygen Absorber will have a loose powdered feel when pinched. It should feel free of clumps and may feel warm (a by-product of the absorber working in a moist environment). Spent (or expired) 300cc Oxygen Absorbers can feel hard or crunchy.
The factors to consider when calculating how many 300cc Oxygen Absorbers you require are: • The volume of the sealed package • The volume occupied by the food product. The 300cc Oxygen Absorber calculation isolates the volume of the food packaging void – sealed package volume less food weight – multiplied by 20%. The factor of 20% reflects that our atmosphere comprises 20% oxygen and 80% nitrogen. For those who like the numbers, the formula is:
(Sealed package volume – food volume) × 20%
. And for those who prefer a shortcut (who doesn’t),

300cc Oxygen Absorbers more rapidly capture oxygen at room temperature. Under normal room conditions (20°C), packages will be oxygen-free within 24 hours. At a temperature of 6°C, packages will be oxygen-free within 48 hours. In 0°C to 4°C conditions, packages will be oxygen-free within 72 hours. Given the content moisture levels can differ widely, we suggest customers test for their own unique circumstances.
Both these methods are used to remove the oxygen content from a package. Vacuum packaging achieves this by sucking out all air and then sealing the package. Nitrogen flushing forces the heavier nitrogen gas into packaging, pushing out the oxygen content. In both instances, some oxygen remains. It is estimated that when these methods are used there can be 2–3% of oxygen remaining. 300cc Oxygen Absorbers can then be used to capture the residual oxygen present.
300cc Oxygen Absorbers are used in sealed packaging to: • Extend shelf life of dried foods, powders, and snacks. • Prevent mold and bacterial growth by removing oxygen. • Preserve beef jerky, dried meats, and protein powders. • Protect grains, dehydrated fruits, and flour from spoilage. • Stop oxidation in pharmaceuticals and electronics. They work best in airtight containers like Mylar bags, vacuum-sealed bags, and food storage jars.
