The PM Series leaks utilize a durable 7740 Pyrex glass permeation leak element that permits diffusion of helium gas. Helium diffuses through the glass membrane at a constant rate determined by the membrane thickness and surface area. These leaks are highly resistant to clogging by nature of their design.
If a calibrated leak has a rate of 1×10 e-8 std. cc/second, then 1 standard cc will diffuse through the walls in 10 e8 seconds which is close to 3 years. Because the reservoir holds about 100 standard cc of Helium, the rate will fall by 1 percent at the end of 3 years.
