Alternatively, you may attach the helium leak detector to any of the demountable connections that you already have on your system, such as standard taper joints (see Fig. 7.63). Always use a hose clamp on both ends of the tube connecting the helium leak detector and the vacuum system being tested to ensure a leak-tight fit. 

In spite of early claims and counterclaims, there are no disadvantages to the demountable capsule and other manufacturers have followed suit and now also supply demountable detectors. For most users, this offers no advantage other than a flexibility that they may never need. Certainly, for the manufacturers there are significant advantages in that a detector need not be committed to a particular Dewar configuration until just before shipping. Because of this, it is a possibility that the demountable detector will become the norm for aU manufacturers.
