Specification AgeRangeDescription : Adult Brand : VERIMP BulletPoint1 : Purpose: This set of equipment can be used for various demonstrations involving real (thin air) aspects in middle school physics and elementary school nature courses. BulletPoint2 : This set of equipment consists of: aspirating disk, bell jar, music generator, sealant for sealing, rubber gasket, etc. It must be used in conjunction with aspirating disk machine or dual-purpose gas cylinder during demonstration experiments. BulletPoint3 : Sound propagation experiment: Put the bell cover on the beat plate with the music generator, and you can hear clear music through the bell, and then remove the air from the bell cover, the music will gradually weaken until it is almost inaudible Sound, turn off the exhaust plate valve. Let the students observe that although the music of the music generator is still ringing, they cannot hear the music. BulletPoint4 : Low-pressure boiling experiment: Put a cup of hot water that has stopped boiling into this set of equipment, and then pump the air, you can quickly see the hot water in the cup boil again. BulletPoint5 : In addition, this instrument can also be used for experiments such as vacuum fountain, evaporation and freezing, vacuum coating, oxygen required for combustion, and atmospheric pressure.
