The SKC 222 low flow sample pumps have long been recognized as the most dependable and durable pumps in the industry. These miniature diaphragm-type pumps are ideal for on-worker or area sampling of gases and vapors in air. Using reliable stroke counter technology, the 222 low flow pumps offer both a suction port for sorbent tubes and a pressure port for sample bags. SKC sample pumps have special patented valves that close positively; this is important because the heart of any pump is its valves. With over 35 years of use in the industry, the 222 low flow pumps have demonstrated their reliability.
