  • Hypochlorite (NaOCl): 50 to 200 ppm
  • Hydrogen Peroxide (H₂O₂): 100 to 200 ppm

Storage and handling

• Elements are filled with glycerin when new, which is part of the fiber manufacturing and preservation process.
• Elements must be stored in a dry and normal ventilated location, away from any sources of heat, ignition, and direct sunlight in the original packing.
• Storage temperature: 5°C and 35°C (45°F to 91°F).
