A new volumetric, suction-type drum sampler (the 7-Day Drum Spore Sampler) has been developed. Fungal spores, pollen grains, and other airborne particles are impinged on double-coated cellophane tape applied to a 15.24-cm (6-inch) diameter drum. The sampling surface of the drum rotates past the orifice at 60 mm in 24 hours so collections can be time related. The sampler body rotates, keeping the intake orifice facing into the wind. Flow rates may be adjusted by air-flow meter from 0.5 to 28.3 liters per minute. Operation is continuous with either 115 V or 230 V AC vacuum pumps.
