【Product Description】

This product is one of the main components for “C15-6065-W0 Atmospheric Pressure Experiment Set M” (refer to the URL below) that is simply designed to carry experiments under reduced pressure.

【Overall Advantages to Users】

•  It is easy to create a reduced pressure state. The lid of the jar is equipped with two identical suction inlets: one is used as a connection to a vacuum pump, while the other one is used as a connection to a tube with a pinchcock. This is used for controlling the pace of returning the internal pressure of the jar from a reduced state to an atmospheric one.

• It is easy to maintain a reduced pressure state. A ring-shaped neoprene gasket underneath the lid prevents influx of outer air from going into the jar and keeps the reduced pressure state inside the jar.
