Sampling isolators, because of their great variety, are typically customized systems. Some are single-glove systems, for example. And due to the nature of their sampling work, they need the ability to connect to most types of sampling ports on a wide range of equipment.
With sampling isolators, ergonomics are generally a secondary concern because the systems are used for short-duration work.
Challenge areas to watch with sampling isolators:
Isolator/equipment interface (the isolator often must be fitted to existing equipment in demanding environments)
Small dimensions of sampling ports complicate connections
Limited space available around the sampling port
Environmental conditions (e.g., explosion-proof areas, heat, pressure differences)
Operator safety around process equipment (e.g., heat, vapors)
Transfer of samples outside the isolator
Requirement for sampling process tools
