All sizes contain the same fast‑acting absorbent formula. The difference is simply the quantity and intended usage:

• 10g sachet – ideal for single small spills or inclusion in portable first aid kits.
• 100g shaker bottle – suitable for regular use and allows controlled application.
• 500g tub – designed for environments where larger or more frequent spills may occur (inferred from product range and typical usage).
• 1kg tub – best for high‑traffic workplaces such as hospitals, schools, and industrial sites; marketed as a biohazard absorbent powder for rapid spill containment.

All formats are CE‑marked and suitable for biohazard spill control.

To use the granules:

1. Sprinkle liberally over the spill area.
2. Wait for the liquid to gel or solidify (typically within 70 seconds).
3. Remove the gelled material using a scoop and scraper, then dispose of it in an appropriate biohazard waste bag. This usage method is confirmed across multiple product listings

BioSafe Super Absorbent Granules are designed for the rapid containment and clean‑up of body fluid spills, including blood, vomit, and urine. When sprinkled onto a spill, the granules absorb the liquid and turn it into a gel within around 70 seconds, making the spill easy to remove safely.
This is supported by Crest Medical’s description noting that the granules rapidly contain spillages and convert liquid into a solid form for safe disposal.
