A glass funnel is a laboratory apparatus used to transfer liquids or fine-grained substances into containers with narrow openings. Here are some key details about a glass funnel:
Description
- Material: Typically made of borosilicate glass, which is resistant to thermal shock and chemical corrosion.
- Shape: Consists of a conical upper section (the wide part) and a cylindrical lower section (the narrow stem).
- Size: Comes in various sizes, typically described by the diameter of the top opening and the length of the stem.

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.
Atomic Model Set
A lab atomic model set is a collection of physical models and materials designed to represent the structure of atoms and molecules. It is commonly used in educational and scientific laboratory settings to visually demonstrate the arrangement of protons, neutrons, and electrons within an atom, as well as the bonding patterns between atoms in molecules. These sets typically include colored balls of various sizes representing different types of atoms, as well as connectors or magnets to simulate chemical bonds between them. The purpose of these sets is to help students and researchers better understand the principles of atomic and molecular structure in a tangible and interactive way.
Beaker Simax
A glass beaker is a cylindrical, open-top container made of glass, typically with graduated volume markings on its side. It is commonly used in laboratories for holding, mixing, and heating liquids, as well as for performing various experiments and chemical reactions. Glass beakers come in various sizes and are designed to provide easy observation of the contents and to withstand temperature changes without significant deformation or chemical interaction with the substances being used.
bell in vacuum with air pump with plate
A "bell in vacuum" apparatus is a scientific setup used to demonstrate the effects of reduced air pressure (vacuum) on sound transmission. It typically consists of a bell or sound-producing object enclosed within a sealed chamber from which air has been removed, creating a low-pressure environment. This apparatus is designed to illustrate how sound travels differently in a vacuum compared to in normal atmospheric conditions, highlighting the role of air molecules in sound propagation.
Bernoulli Tube Apparatus
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.
Blotting paper
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.
