Vacuum chamber, 1000 ml, with manometer

Robust vacuum vessel for air-pressure and vacuum experiments, including pressure measurement, boiling at reduced pressure, implosion demonstrations, sound transmission in an airless space, mass-of-air experiments and free fall with the SE free-fall tube. It includes a silicone sealing ring, a lid with a transparent vent valve, an attached manometer for precise pressure display, a quick coupling for the vacuum hose and an easy-to-use inlet valve.
