A sampling device samples gas from a gas stream flowing through a tube to means utilizing the gas to detect the presence or otherwise of particulate contaminants. The device ensures that the sampled flow has at least as many particulate contaminants/unit volume as the main flow. The device divides the flow into two parallel flows and then decelerates one flow before providing the sampled flow. The other flow passes to the utilizing means. The device is particularly useful in the sterile packaging of product to detect microorganisms and other culturable contamination.

Sampling devices

A gas sampling assembly takes a sample of a gas and passes the gas through a monitoring unit. A material within the unit removes particulates from the gas and a port is provided for feeding into the unit a material for indicating the presence of particulates. A transparent portion of the unit allows the indication to be viewed. The unit can be used in sterile packaging apparatus.
