A recirculating water aspirator can help mitigate wastage. Their historic popularity stemmed mainly from their low purchase price. While suitable for use in rotary evaporation or filtration systems using funnels or solid-phase extraction cartridges, water aspirators do not reach the deeplevel vacuum required for certain applications, such as evaporating high-boiling-point solvents, according to Jason Wagner, vice president of marketing in North America at BCHI Corporation (New Castle, DE). The operating principle is molecular momentum; rapidly spinning vanes collide with air or vapor molecules and impart momentum that moves these molecules in the direction of exhaust. If you wanted to keep things from splashing around back in your hood, you attached some rubber tubing to the other end of the thing and ran it further down the drain a bit.Well, one day, one of the guys in the lab next door to me was shocked to see water blasting around in his hood. Since central systems are installed during original construction, they are unable to adapt as needs change over the life of a lab building without being overbuilt to meet all possible future needs. It requires no oil what so ev. Available in handheld and portable sizes for easy access and use, the vacuum aspiration systems create a stable vacuum for reliable results. As Peter Coffey, vice president of marketing at VACUUBRAND (Essex, CT), explains, another drawback of water aspiration is that the end vacuum depends on the water pressure of the faucet and the water temperature. There they can lead to cross-contamination between vacuum applications in different labs, or simply condense in the tubing and deposit there as an unknown mix of chemicals over the life of the building. Many laboratoriesespecially in older lab buildingsare equipped with central vacuum (sometimes called house vacuum) systems. Anderson adds that water aspiration often leads to water contamination, as these devices can draw up volatile solvents, which then get carried through the device and down the drain. The best approach is to study the pump performance curves (see Figure 3). Figure 2 - Welch model 2522 WOB-L piston pump (courtesy of Welch-Ilmvac, Niles, IL).
