Packing:
-
- 38 liters HDPE drums
- 250 liter HDPE drums
- 1000 liter HDPE drums

Handling: Use of approved respiratory systems, goggles, gloves & suitable clothing is recommended.
Storage: Storable under controlled temperature conditions (25 0C – 30 0C) depending on methanol content.
Formalin is stabilized with benzoguanamine (~0.1%) in order to make it possible to store the product at room temperature without forming paraformaldehyde.
