Proof Plane

Original price was: $550.00.Current price is: $400.00.

A proof plane is a small, flat, conductive disk, typically made of metal, that is used in electrostatics experiments to sample electric charge from a surface. It serves as a tool to study charge distribution and behavior on conductors and insulators. When the proof plane makes contact with a charged object, it collects a small amount of charge, which can then be transferred to an electroscope or electrometer for measurement. This allows researchers to analyze electric fields, verify polarization, and demonstrate principles of electrostatics, such as charge conservation and transfer. Its design facilitates precise interactions with charged surfaces, making it essential for educational and experimental applications in physics.

Description

Uses of Proof Plane

  • Measuring Charge Distribution:

A proof plane is used to touch different parts of a charged object to sample the charge. This can help in determining how charge is distributed across the surface of a conductor.

  • Testing Conductors vs. Insulators:

By transferring a small amount of charge to an electroscope, a proof plane can help identify whether an object is a conductor or an insulator based on how charge behaves on the surface.

  • Detecting Polarization:

It can be used to study the polarization of objects by picking up charges from polarized surfaces and measuring the effect using an electroscope or electrometer.

  • Charge Transfer Demonstrations:

The proof plane can transfer charge between objects to show the principles of charge conservation and transfer during contact.

  • Verifying Electric Field Strength:

By placing the proof plane in different parts of an electric field, you can use it with an electrometer to measure the strength and direction of the field.

Amber Bottles Polystop

$0.01
A laboratory glass amber bottle is a specialized container commonly used in laboratories to store and protect light-sensitive substances, chemicals, or solutions. These bottles are made from amber-colored glass, which provides protection against ultraviolet (UV) and visible light radiation. The amber glass helps to minimize the degradation and decomposition of light-sensitive contents by blocking a significant portion of the light spectrum. The amber color of the glass is achieved by adding iron, sulfur, and other compounds during the glass manufacturing process. This coloration is what gives the bottles their distinctive amber or brown appearance. Laboratory glass amber bottles typically come in various sizes, ranging from small volumes of a few milliliters to large capacities of several liters. They often have a screw-on or snap-on cap, providing a secure and airtight seal to prevent spills, evaporation, and contamination. Due to their ability to protect light-sensitive substances, laboratory glass amber bottles are widely used in chemistry, biology, pharmaceuticals, and other scientific fields where sample integrity and stability are crucial.

Aspirator Bottle Glass

Original price was: $6,500.00.Current price is: $5,500.00.
A laboratory aspirator glass bottle, also known as a vacuum aspirator bottle or a vacuum filtration flask, is a specialized glass container used in scientific laboratories for various applications. It is designed to create a vacuum or negative pressure, which allows the filtration of liquids through a porous medium like a filter paper or a membrane. The bottle typically has a conical or pear-shaped body with a sidearm or neck near the top. This neck is where a rubber or silicone stopper is inserted, allowing for the attachment of tubing or a hose to connect to a vacuum source or water aspirator. (Available in 2.5l,5l,10l,) Laboratory aspirator glass bottles are commonly used in vacuum filtration processes to separate a solid precipitate from a liquid solution. When connected to a vacuum source, the air inside the bottle is removed, creating a pressure difference that draws the liquid through the filter, leaving the solid behind on the filter paper. These bottles come in various sizes to accommodate different filtration needs and are an essential tool in many research, analytical, and quality control laboratories for tasks like separating particulate matter, sterilizing solutions, and performing various filtration techniques. They are often made of durable borosilicate glass to withstand the pressure changes and chemical interactions that may occur during laboratory operations.

Bernoulli Tube Apparatus

$0.01
The Bernoulli tube apparatus, also known as a Venturi tube apparatus, is a scientific device used to demonstrate the principles of fluid dynamics, particularly the Bernoulli's principle. It consists of a specially shaped tube with a constricted region, often referred to as a Venturi section. When fluid (liquid or gas) flows through the tube, the constricted section leads to changes in pressure and velocity according to Bernoulli's principle, which states that as the velocity of a fluid increases, its pressure decreases and vice versa. This apparatus is commonly used in educational settings to visually illustrate how the flow of a fluid can affect its pressure, helping to explain various phenomena like lift in aircraft wings, fluid flow through pipes, and more.
