The new Apex series of personal air sampling pumps from Casella provides flow rates from 5 ml/min - 5 L/min. The 17-oz. Apex Sampler, which the company says is the lightest weight, true 5 L/min pump available, offers a large LCD and simple menu-driven functions. The engine is a high-performance, ultra-narrow, double-diaphragm pump.
