1415 One-stage vacuum pumpThe rotary vane vacuum pump is designed to create vacuum in a sealed container. Technical features: single-stage; recycled lubrication, tank, fan, silencer. Capacity: 1 m3/h. Minimum pressure: 10-30 Pa. Engine power: 90W. Power supply: 230 V. It is supplied with oil and vacuum tube (1m).
1068 Plate for bell jarThe Pneumatic plate is made of perfect sealing ground metal and is provided with a disk of para rubber in order to increase its resistance. It has two stopcocks: one of them is used to connect the vacuum pump while the other one is used to restore the atmospheric pressure.
1374 Pressure surprisesTo demonstrate how air flows due to air pressure, use two balloons with different amounts of air in them. When you open the linking stopcock between the balloons, you would expect to see the air flowing from the most inflated Balloons into the less inflated one.But..
1107 Empty Newton’s tubeInside this tube there is a sufficient vacuum, It contains a ball and a feather. Making them fall together from one end, it is observed that they reach the bottom of the tube at the same time, indeed the acceleration of gravity is independent of the mass of the body. It is made of glass; It doesn’t have air inside, but a feather...
1070 Newton’s tube (to be emptied)It has stoppers and stopcock to link it to a vacuum pump, after having placed small item inside it. In this way it’s possible to realize a sufficient vacuum. Making the items fall from one end, it is possible to observe that they reach the bottom of the tube at the same time, indeed the acceleration of gravity is...
1043 Torricelli’s experiment apparatusIt enables you to perform the classic Torricelli’s experiment, thanks to the tube (length 85 cm, D 6 mm) with chemically carved millimetric division on the glass all along the interested part. It is supplied with base, basin, stands and funnel. Mercury is sold separately.
