Bell in Vacuum JarKWD 88.000
Bell in Vacuum Jar
KWD 88.000SKU: 0914-0119 Category: Instruments
- This is one of the apparatus to be used in scientific laboratories to demonstrate that sound needs a medium to travel.
- Turn on the bell placed in this vacuumed jar.
- Now during this experiment the sound that will be produced in this jar is not audible to our ears, as the sound waves can’t travel in a vacuum state and they need a material medium for its propagation.
- It can also place on pump plates to perform experiments with diameter at least 15cm.
- Excellent demonstration tool for science classrooms.
- Size of Bell Jar : 9″x6
Air Track Liner With PumpKWD 1,760.000
Air Track Liner With Pump
KWD 1,760.000SKU: 0914-0004 Category: Instruments
- Air Track is one of a scientific instrument which is used to study the motion of in an environment consisting of low friction.
- The air is pushed through an empty track and, the track is having fine holes.
- These air tacks are of triangular shapes in cross sections.
- Carts with triangular base fits perfectly on the top of track and is used in observing motions in low friction environments.
- Air track instrument is used to study collisions in both cases elastic and inelastic.
- As, the energy lost due to friction is very less in amount so that we can easily demonstrate how momentum is conserved before and after collision.
- Moreover the track is also used to calculate the force of gravity, when it is placed at any certain angle.
Barometer AneroidKWD 15.000
KWD 15.000SKU: 0914-0140 Category: Instruments
- Aneroid Barometer is a scientific instrument that is used to measure atmospheric pressure (with the change of the distance below and above sea level). It is also names as barometric pressure.
- Barometer is kept at the same level and can measures easily the pressure changes by weather and different causes of weathers.
- Measuring air pressure using these instruments the usage of liquid is not required.
- The instrument is designed with a small metal box named as Aneroid cell (Capsule) it is designed from alloy of Beryllium and Copper.
- This expansion and contraction procedure drives mechanical levers i.e. the tiny movements of this capsule are amplified and are displayed on the screen of measuring barometer.
- It is also used in different meteorology, in barographs and to create pressure in radiosonde.
- Aneroid barometer is highly a sensitive instrument and can be used to record small changes in pressure.
Clip Crocodile BlackKWD 5.000
Clip Crocodile Black
KWD 5.000SKU: 0914-0204 Category: Instruments
- Crocodile clips are designed sprung metal clips with long and serrated jaws.
- They are used to create temporary electrical connections.
- The clips are used in testing and evaluating electronic items. One jaw of this clip is permanently crimped to a wire. It is signed to form the inner tubular contact of 4mm.
- The clips are covered by plastic boot to prevent accidental short circuits.
- These clips are also used to make connections between automobile batteries.
