Air Pump Vacuum
Product Code : JA-SW-7590
The Air Pump Vacuum (SKU JA-SW-7590) is a vacuum pump supplied with a 250 mm pump plate, used with bell jars to create a vacuum environment for physics experiments. Its best-known use is the bell-in-vacuum demonstration, in which a ringing bell grows fainter as air is removed, but the same pump and plate serve other experiments that need a bell jar under reduced pressure. JaincoLab supplies this vacuum air pump and plate to school and college physics laboratories.
Specifications
The Air Pump Vacuum comprises a pump and a 250 mm pump plate on which a bell jar is placed, so that air can be drawn out of the jar to create the vacuum environment needed for experiments on sound and on the effects of removing air from a closed space.

Experiments with the vacuum air pump and bell jar
Teachers use the vacuum air pump and plate to evacuate a bell jar, most often to show that sound needs a medium to travel: as the air is pumped out, a ringing bell inside the jar becomes quieter even though it can still be seen ringing. The same set-up supports other demonstrations that need reduced air pressure.
- Showing that sound does not travel through a vacuum, with a bell inside a bell jar
- Air pressure demonstrations, such as a partly inflated balloon expanding inside the evacuated jar
- Middle and secondary school lessons on how sound travels
- College physics demonstrations that need a bell jar under reduced pressure
Scope of supply and ordering
The listing covers the vacuum pump with its 250 mm pump plate. Bell jars and the bell unit are listed separately (Acrylic Bell Jar, Bell in Vacuum), so a complete set can be quoted together. Accessories, spares and quantities are confirmed on the quotation.
Minimum order quantity, lead time and packing are confirmed on each quotation according to the quantity and the delivery destination. JaincoLab supplies single units for school laboratories and larger quantities for colleges, education programmes and export buyers in Africa, the Middle East and South and South-East Asia.
