Description
Uses of Hand stroboscope
- Density Comparison:
- Educational Demonstrations: Hare’s Apparatus is used in classrooms and laboratories to visually demonstrate the concept of density and how it affects the height of liquid columns.
- Experimental Determination: It allows students and researchers to determine the relative densities of two immiscible liquids by comparing the heights of the liquid columns in the two connected tubes.
- Hydrostatic Pressure Studies:
- Principle of Hydrostatic Pressure: The apparatus helps illustrate how different liquids exert different pressures at the same height due to their varying densities.
- Pascal’s Law: Demonstrates Pascal’s principle by showing how pressure applied to a fluid is transmitted equally in all directions.
- Buoyancy and Archimedes’ Principle:
- Understanding Buoyancy: By comparing the densities of different liquids, students can better understand the concept of buoyancy and why objects float or sink in different liquids.
- Viscosity Studies:
- Flow and Viscosity: While primarily used for density comparison, Hare’s Apparatus can be adapted to observe the flow characteristics of different liquids, providing insights into their viscosities.
- Material Science:
- Solubility and Miscibility: It can be used to study the miscibility of different liquids and their solubility properties, which is important in material science and chemical engineering.
- Thermodynamic Studies:
- Temperature Effects on Density: By conducting experiments at different temperatures, students can observe how temperature changes affect the density of liquids, linking to concepts in thermodynamics.
- Calibration and Verification:
- Instrument Calibration: It serves as a simple tool for calibrating other instruments that measure liquid density, by providing a straightforward method for density comparison.
- Quality Control: In industrial laboratories, it can be used for quick quality control checks to ensure the consistency of liquid densities in processes such as food and beverage production.
- Chemical Analysis:
- Purity Testing: The apparatus can help in assessing the purity of liquids, as impurities often alter the density of a liquid.

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
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.

A plastic beaker is a laboratory container made from plastic material, typically featuring a cylindrical shape with a flat bottom and a spout or pouring lip. It is used for holding, measuring, and mixing liquids or substances during various scientific experiments, research, or educational activities. Plastic beakers come in a range of sizes and are designed to withstand various chemicals and temperatures, making them versatile tools in laboratory settings.
Blotting paper
$0.01
Blotting paper is a highly absorbent and thin sheet of paper, typically made from materials like cotton, linen, or other plant fibers. It is designed to quickly absorb excess liquids, such as ink, oil, or moisture, from various surfaces without smudging or smearing the substances. Blotting paper is commonly used to remove excess ink from a freshly written page, absorb oil from the skin without disturbing makeup, or dry wet items. It is often found in office settings, art studios, and cosmetic applications due to its efficient absorption properties.
