ORBO PUF Cartridges

Several EPA and ASTM methods require a polyurethane foam (PUF) cartridge for monitoring semi-volatiles in stack, ambient, indoor, and workplace atmospheres.
Our large PUF cartridges allow sampling rates up to 225L/min with low pressure drop. Small PUF cartridges are useful for the 1-5L/min sampling range.
