Moisture Permeability of Glove Materials for Controlled-Atmosphere Boxes

A controlled atmosphere chamber

“…Neoprene gloves [18, 19] are clamped over the glove holes by means of ¼ in. thick brass rings of 6 in.…”

Inert-Atmosphere Dry Box

“…cm. each, and using Rowan's figures (9) the four gloves, distended, might permit about 200 mg. of water per hour to diffuse into the box from an ambient atmosphere of 58% humidity. If an operator is working with the gloves, the figure approaches 100%, when the rate of permeation is doubled.…”
