Description

Demonstrate the effect of a partial vacuum on inflated balloons and other objects with this easy-to-use pump. The pump removes 15 mL of air with each squeeze of its comfort-grip handle and pulls a vacuum down to 50 mm of mercury. A release valve lets you release the vacuum without disconnecting the pump from the line. Includes 12" of 3/16-ID tubing and instructions. Without gauge.
