Now available with built-in gauge. -- These two-stage high-vacuum pumps both offer an ultimate vacuum of between 1.33 x 10-2 Pa to 3.3 Pa actual pressure of residual gasses, free air displacement of 85 liters per minute, a pump speed of 1725 rpm- and surprisingly quiet! -01 has a built-in gauge. Intake connections are via 1/4 inch ID tubing. -- These features make this pump an excellent choice for demonstration lectures and lab work. Weighing only 12.7 kg, the pump is UL and CSA listed, and has a carrying handle. Dimensions are approximately 29 cm x 39 cm x 16.5 cm. Operates on 120V, AC. Both models deliver low enough pressure for all Boyles Law Experiments. -- The version with gauge (shown) reduces error due to a poor seal when gauges are added between the pump and the vacuum plate. |
