Top 5 Lab Electroscopes & Van de Graffs
Eisco Labs Demonstration Electroscope
The Eisco Electroscope is a demonstration apparatus designed to detect and measure static electric charges. By inducing or conducting a charge through the metal plate on top, the electroscope needle attached to the central rod deflects, indicating the presence and magnitude of the charge. With dimensions of approximately 10.6" x 6.3" x 4.7", and a 5.9" diameter conductor sphere, this electroscope is compact and portable. Whether you're a student or a science enthusiast, the Eisco Electroscope is a valuable tool for understanding and exploring the world of electricity. Its clear display of charge deflection allows for easy observation and measurement, making it a convenient and informative device. With the Eisco Electroscope, you can engage in hands-on experiments and gain a deeper understanding of static electricity.
Eisco Labs Aluminum Leaf Flask Electroscope
The Eisco Electroscope is a lab instrument designed to detect electric charges and determine polarity. With a height of 7.5 inches and a diameter of 3.5 inches, this electroscope features a glass conical flask, a brass rod, and an aluminum leaf. The glass conical flask provides a sturdy and transparent container for the electroscope, allowing users to easily observe any electrical charges. The brass rod and aluminum leaf are essential components that enable the electroscope to detect and indicate the presence of electric charges. This compact and reliable instrument is perfect for educational purposes and scientific experiments, providing users with a convenient and accurate way to explore the world of electricity.
Eisco Pith Electroscope
The Eisco Electroscope is designed to help you explore the fascinating world of static electricity. It features two pith balls suspended from unspun silk, allowing you to easily observe static charge interactions. The pith balls are supported by a sturdy brass pillar, which is mounted on a durable plastic base, ensuring stability during experiments. This setup is particularly useful for educational purposes, making it ideal for students aged 14 to 21. With this device, you can conduct experiments that illustrate fundamental principles of electricity in a hands-on manner.

Frequently Asked Questions (FAQs)
1. What is the conclusion of electroscope experiment?
The conclusion of an electroscope experiment is that it works based on charge induction, the atomic and internal structure of metal elements, and the principle that unlike charges attract while like charges repel each other.
2. What is the use of electroscope in the laboratory?
The electroscope is a scientific instrument used to detect the presence of electric charge on a body. It detects charge by observing the movement of a test object due to the Coulomb electrostatic force acting on it. The amount of charge on an object can be determined by measuring its voltage.
3. What is the objective of the electroscope experiment?
The objective of an electroscope experiment is to identify whether an object is positively or negatively charged. By bringing a negatively charged object near the electroscope, the electrons in the instrument will be repelled towards the leaves, resulting in the movement of the leaves towards each other.
