What distinguishes a sampling valve from any other type of valve is the method of collection and the sampling receptacle. At BIAR, we offer numerous sampling collection options, based on the characteristics of the chemical being sampled. For applications in which the sample is not hazardous and is not adversely affected by exposure to the surrounding environment, a collection bottle that is screwed to the valve is typically used. This is the simplest collection method available and provides and a straightforward means of sample retrieval.
