4746 Acid Digestion Vessel

A Product by Orlab

4746 High Pressure Acid Digestion Vessel, 23 mL, 5000 psig

This is the original acid digestion vessel introduced by Parr in 1969 to provide a PTFE lined metal vessel of simple design and minimum cost that can be used safely for routine sample preparation purposes. Its wide acceptance over the intervening years has proved it to be an excellent design for general digestion procedures in which temperatures and pressures are held below 150 °C and 1200 psig. It can be used occasionally above 150 °C, but at elevated temperatures it becomes increasingly difficult to maintain a tight seal.

The 4746 High Pressure Acid Digestion Vessel has a safety rupture disc that will release through a passage in the bottom of the vessel. The nickel vessel does not have a blow-out passage since reactions with reducing acids are not potentially explosive.
