Acetonitrile (CH₃CN) is a colorless, volatile, and flammable liquid with a sweet, ether-like odor. It is widely used as a polar aprotic solvent in organic synthesis and chromatography, especially in HPLC (High-Performance Liquid Chromatography). Acetonitrile is miscible with water and many organic solvents. It is toxic in high concentrations and should be handled with proper safety precautions.

ACETONE
Acetone (CH₃COCH₃) is a colorless, volatile, and flammable liquid with a sweet, fruity odor. It is a widely used solvent in industries, laboratories, and cosmetics (e.g., nail polish remover). Acetone is miscible with water and many organic solvents. It evaporates quickly and is used for cleaning, degreasing, and in chemical synthesis. Prolonged inhalation can be harmful.

AGILENT HPLC
Agilent HPLC (High-Performance Liquid Chromatography) systems are advanced analytical instruments used for separating, identifying, and quantifying compounds in a mixture. Manufactured by Agilent Technologies, these systems are widely used in pharmaceuticals, environmental testing, food safety, and chemical research. Agilent HPLCs are known for their high precision, reliability, and user-friendly software (such as OpenLab or ChemStation). Common models include the Agilent 1100, 1200, and 1260 Infinity series.

AMMONIA SOLUTION TECH-GRADE
Ammonia solution (technical grade) is a water-based solution of ammonia gas (NH₃), typically containing 25–30% ammonia. It is a colorless, pungent-smelling, alkaline liquid used in industrial cleaning, water treatment, fertilizers, and chemical manufacturing. Technical grade is not purified for food or pharmaceutical use. It is corrosive and toxic, requiring proper handling, ventilation, and protective equipment.

AUTOCLAVABLE MECHANICAL MICROPIPETTE
An autoclavable mechanical micropipette is a laboratory instrument used to accurately measure and transfer small volumes of liquids, typically ranging from 0.1 µL to 1000 µL. It is designed with durable materials that allow for sterilization in an autoclave at 121 °C, ensuring contamination-free usage. These micropipettes offer adjustable volume settings, ergonomic handling, and high accuracy and precision. They are widely used in molecular biology, microbiology, and analytical chemistry. The autoclavable feature makes them ideal for sterile environments, such as tissue culture or clinical labs. Their design ensures reliability and comfort during repetitive pipetting tasks.

BEAKER
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.

BIOLOGICAL SAFETY CABINET
A Biological Safety Cabinet (BSC) is a ventilated laboratory workspace designed to protect the user, the environment, and the materials being handled from exposure to biohazards and infectious agents. It uses HEPA (High-Efficiency Particulate Air) filters to clean the air entering and exiting the cabinet. Unlike chemical fume hoods, BSCs also maintain a sterile environment for sensitive biological samples. There are three main classes (I, II, and III), with Class II being the most commonly used in microbiology and biomedical labs.

BLADDER
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.
-
BOILING FLASK
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.

BOTTLE-TOP DISPENSER
A bottle-top dispenser is a laboratory device mounted on reagent bottles to safely and accurately dispense specific volumes of liquid chemicals directly from the container. It is widely used to avoid spillage and reduce contamination during repetitive liquid handling.
-
BURETTE
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.

CalCHECK
CalCheck is a convenient and reusable LED device used to quickly and reliably verify the calibration of a Hygiena luminometer. Simply insert CalCheck into a Hygiena luminometer and run a test in seconds. While the Hygiena luminometer runs a calibration self-check at startup, CalCheck provides validation and supports a robust quality control program. CalCheck provides an all-in-one, reusable positive and negative calibration verification device, activated simply by the click of a button.

CENTRIFUGE TUBE
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.
-
COD DIGESTION UNIT
A COD digestion unit is a laboratory device used to measure the Chemical Oxygen Demand (COD) of water or wastewater. It heats samples with a strong oxidizing agent (usually potassium dichromate in sulfuric acid) at 150°C for two hours. This process oxidizes organic matter, indicating pollution levels. It’s essential for water quality analysis in environmental monitoring.
