This grid is the typicaldesignation of body materials. Slight variations may occur due to raw material availability.1) Note the material designation imprinted on the valve body or associated tag. The marking includes the valve style, size letter, and body material.
Radial immunodiffusion (RID) is a technique that can quantitatively. determine the concentration of an antigen. Unlike many gel and liquid. precipitation techniques which qualitatively detect antigen, RID is a. sensitive quantitative technique that is often used clinically to detect. patient levels of blood proteins.
Industrial borescopes allow for remote visual inspections (RVI) in areas where it is difficult or impossible for the human eye to see into directly.However, the term âborescopeâ has become a generic term to describe four types of products/technologies used for internal inspections.While there are key differences between these inspection cameras, the earliest RVI product was called a âborescopeâ â the name stuck even as new technologies were developed.igid borescopes are simple tubes shaped like long, thin telescopes that use a lens system to send an image to a relay lens from the object to be viewed in real-time. This is accomplished with an eyepiece on the proximal (near) end and an angled mirror pointed toward an opening in the tube on the distal (far) end.
