General description
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.

When it means 1/8 fitting, does it mean I can connect it with a tube with internal diameter of 1/8 or the external diameter has to be 1/8?

Does the product include an indicator for the consumption of sodium oxides?
1 answer-
Upon the absorption of CO2, the greenish-brown material turns white due to the formation of sodium carbonate. It is designed to remove CO2 from gases used in various applications, such as carbon-hydrogen determinations, analyses of respiratory gases, and especially in quantitative organic micro-analyses. The sodium hydroxide non-fibrous silicate trapping medium is widely recognized for its high absorptive capacity and indicating properties. Typically, this material will absorb 20-30% of its weight in carbon dioxide before replacement of the saturated material is required.
