A hydrometer is an instrument used to measure the specific gravity (relative density) of liquids. It consists of a sealed glass tube with a weighted bottom, allowing it to float upright. The level to which it sinks indicates the liquid’s density. Hydrometers are commonly used in brewing, winemaking, and battery testing.
Pipette tips are disposable, narrow plastic attachments used with micropipettes to accurately transfer small volumes of liquid in laboratories. They ensure precision, prevent cross-contamination, and are available in various sizes (e.g., 10 µL, 200 µL, 1000 µL). Sterile pipette tips are used in sensitive experiments like molecular biology, cell culture, and PCR.
Polypropylene reagent bottles are durable, chemical-resistant containers commonly used in laboratories for storing and dispensing liquid or powdered chemicals. Made from high-quality polypropylene plastic, these bottles offer excellent resistance to a wide range of acids, bases, and solvents, making them ideal for both general-purpose and specialized chemical storage.
Made of top quality porcelain. Withstand temperatures up to 1150 C. Round form with lip. Glazed inside.
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.
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.
Porcelain crucible is a small, heat-resistant container made from ceramic material, used in laboratories for heating substances to very high temperatures. It is commonly used in ash content analysis, metal melting, and chemical reactions that require intense heat. Crucibles can withstand open flames and are often used with a lid and a clay triangle during heating.
Centrifuge tube is a cylindrical, conical-bottomed container used in laboratories to hold samples during centrifugation. Made of plastic or glass, it is designed to withstand high-speed spinning that separates components based on density. Centrifuge tubes come in various sizes (e.g., 1.5 mL, 15 mL, 50 mL) and often have screw caps or snap lids to prevent leakage during use.
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.
film made of polyolefines and paraffin waxes Service temperature from 45 ?C up to +50C (melting point +60 C) Resistant to saline solutions, most common inorganic acids and bases used in laboratory and some organics solvents (methanol, ethanol and 2-propanol) Not resistant to diethylether, chloroform, carbon tetrachloride, benzene or toluene.
Cuvettes are small transparent containers used in spectrophotometry to hold liquid samples for absorbance or transmittance measurements. Made of glass, plastic, or quartz, they allow light to pass through the sample. Quartz cuvettes are preferred for UV light analysis. They are essential for accurate optical readings and must be handled carefully to avoid contamination or scratches.
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.
