Sigma Aldrich Fine Chemicals Biosciences Carbon Dioxide Trap volume
Supplier: Sigma Aldrich Fine Chemicals Biosciences 503215
Sodium hydroxide nonfibrous silicate material is universally accepted for its high absorptive capacity and indicating properties for carbon dioxide. Typically this material will absorb 20-30% of its weight in carbon dioxide before replacement of the saturated material is required. As carbon dioxide is absorbed the greenish-brown material turns white because of the formation of sodium carbonate. The trap body is constructed of borosilicate glass and the fittings are nickel-plated and have sintered stainless steel frits.A moisture trap should be installed downstream from this unit to absorb the moisture that is produced.Note Exercise extreme caution when refilling the trap due to the caustic nature of the absorbent.Dimensions100Acc Traps 123/4Ain.
