Burette clamps are scientific instruments specially designed to hold a burette on stand.
It helps in performing different experiments more conveniently as the burette will be in a proper fixed position.
These burette clamps are designed with cast iron materials. Moreover the iron clamp is designed with a rubber knob to hold the burette. The clamps can hold two burettes together.
The usage method is to fix a burette clamp on a stand then, squeeze the handle and the rubber knob will be separated from each other.
These rubber knobs are soft and sticky that helps the burettes not to break or separate alike during experiments.
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.
Crocodile clips are used to create flexible, temporary experimental electrical connection in laboratories.
The device could be between two wires or between an electrical lead and the anode or cathode of a device (i.e. the entrance and exit points of an electrical current).
The cloth rubbing wool is used to perform the static electricity experiment.
A cloth rubbing wool is used for rubbing against different materials, such as glass, plastic, balloon, wax.
Wool cloth is used to demonstrate experiments for balloon and wool cloth.
When rubbing a balloon with a wool cloth, the balloon captures electrons from the wool, leaving the balloon with a negative charge and the wool with a positive charge.
If both balloons are rubbed with wool, they will both have same charge (negative) and therefore will repel each other. When you spray water near the balloons.
The water droplets carry the charges away from the balloons, leaving them uncharged. As the balloons become neutral, they will fall back together.
