Dynacal Wafer Device

MetronicsSKU: PDWF-0082

Compound: Sulfur Dioxide wafer cas # 7446-09-5

Overview

Dynacal perm tubes and wafer permeation devices are small, inert capsules containing a pure chemical compound in a two phase equilibrium between its gas phase and its liquid or solid phase. At a constant temperature, the device emits the compound through its permeable portion at a constant rate. Perm tubes and wafer devices are typically inserted into a carrier flow to generate test atmospheres for calibrating gas analyzer systems, testing hazardous gas alarms, or conducting long-term studies of effects on materials or biological systems – in short, any situation requiring a stable concentration of a specific trace chemical
