RACK
Racks are laboratory tools used to hold, organize, and store test tubes safely and upright. They are made of plastic, wood, or metal and come in various sizes to fit different tube diameters. These racks help prevent spillage, breakage, and contamination during experiments, making them essential for safe and efficient laboratory work.

Beaker is a common laboratory container used for mixing, stirring, and heating chemicals. It is usually made of glass or plastic and has a cylindrical shape with a flat bottom and a small spout for easy pouring. Beakers come in various sizes and have volume markings, but they are not used for precise measurements.
A laboratory bladder is a flexible, inflatable membrane or container used in various experimental setups to simulate pressure, store gases or liquids, or mimic biological systems. Made from materials like latex or silicone, it is commonly used in fluid mechanics, biomedical research, or testing equipment to apply controlled pressure or volume changes.
A pycnometer is a laboratory device used to determine the density or specific gravity of liquids and fine solids. It is usually a small glass flask with a close-fitting stopper that has a capillary hole to allow air to escape. Pycnometers provide highly accurate measurements and are commonly used in chemistry and material science.
A vacuum pump with filtration is a system used primarily in laboratories to remove air and create a vacuum for filtration processes. It helps in speeding up filtration by reducing pressure, allowing liquid to pass quickly through a filter paper.
Burette is a long, graduated glass tube with a tap at the bottom, used in laboratories to accurately deliver measured volumes of liquids, especially in titrations. It allows controlled addition of a solution to react with another in a flask. Burettes are marked with precise volume measurements, making them essential for quantitative chemical analysis.
Reagent bottles, also known as chemical bottles or laboratory bottles, are specialized containers used to store chemicals, reagents, and other laboratory substances. They are designed to ensure safe handling, accurate identification, and proper storage of a wide variety of chemical compounds.
A vacuum distillation glass set is a laboratory apparatus used to distill liquids at reduced pressure, allowing substances with high boiling points to vaporize at lower temperatures. This prevents thermal decomposition and is ideal for heat-sensitive compounds.
A stand and clamp is a basic yet essential piece of laboratory equipment used to hold and support apparatus during experiments. It provides stability and helps secure glassware or other tools in place.
The Le Chatelier Specific Gravity Bottle is a specialized glass apparatus used to determine the specific gravity (relative density) of fine materials like cement. It has a narrow neck with a graduated scale and a bulb at the bottom. The bottle accurately measures the volume displaced by a known weight of material, helping assess quality and consistency in construction materials.
Boiling flasks are used for heating and boiling of liquids. The flasks are designed to have round bodies with long, thin necks to facilitate uniform heat distribution and minimize evaporation. Boiling flasks are typically made of borosilicate glass, which is resistant to thermal shock and chemicals. Some boiling flasks have rounded or conical bottoms and need support to stand upright, while others have flat bottoms and can stand alone.
Conical flask, also known as an Erlenmeyer flask, is a laboratory container with a conical body, flat bottom, and a narrow neck. It is used for mixing, heating, and storing liquids. The narrow neck helps reduce spillage and allows for use with stoppers. It is ideal for titrations, as it can be easily swirled without risk of spilling.
Cell culture plate is a flat, sterile plastic or glass plate used in laboratories to grow and study cells under controlled conditions. It contains multiple wells (like 6, 12, 24, 96, or 384) where cells are cultured in nutrient media. These plates are essential in biological research, drug testing, and tissue engineering for observing cell behavior and responses.
