The new Masterflex L/S variable-speed console drives (photo) sit neatly on a bench or in a fume hood in any laboratory, providing simple operation with single-turn speed control. These drives accept nine different Masterflex L/S peristaltic-pump-head types. With a flow range of 0.42 to 2,900 mL/min, it is suitable for general fluid-transfer applications. A separate power switch enables the user to maintain the speed setting when turning the drive on or off. A reversible motor makes it easy to prime or purge the tubing and pump in either direction. A remote-control feature starts and stops the unit via a connector on the back of the drive. — Cole Parmer, Vernon Hill, Ill.
