Capillary Tubes and Drop Pipes
Capillary tubes are lengths of flexible tubing that are connected to the sampling pipe. Capillary tubes are
typically used to sample air away from the air sampling pipe, or in instance where focused air sampling is
required. Capillary sampling is used for in-cabinet sampling and in instances where the sampling pipe requires
to be concealed from the sampling area. Drop pipes are a variation of the capillary tube and serve the same
purpose.

Miniature Sampling Points
Miniature sampling points are attached to the sampling end of capillary tubes. There are two types of miniature
sampling points:
Conical sampling points
Local codes and standards normally specify the minimum distance from the ceiling for air sampling. The
conical sampling points meet these requirements and is more commonly selected as a miniature sampling
point.
Figure 3-7: Conical Sampling Point
Flush Sampling Points
Flush sampling points are normally used when there is a need to conceal the pipe network. Flush sampling
points may not comply with your local codes and standards. These are mostly used for performance based
systems.
