LABORATORY FREEZER
A laboratory freezer is a specialized unit used to store biological samples, chemicals, reagents, and vaccines at low temperatures, typically ranging from –20°C to –80°C. It ensures sample stability and prevents degradation. Laboratory freezers are essential in research, clinical, and pharmaceutical settings for long-term preservation and safety.

A Thermal Gravimetric Instrument (TGA) measures changes in a material’s weight as it is heated, cooled, or held at a constant temperature. It helps determine thermal stability, composition, and decomposition temperatures. TGA is widely used in material science, polymers, and pharmaceuticals for quality control and research applications.
A rotary evaporator (or rotavap) is a laboratory device used to remove solvents from samples through evaporation under reduced pressure. It works by rotating a flask containing the solution, while gently heating it and applying a vacuum, allowing the solvent to evaporate at a lower temperature. It is widely used in chemistry, pharmaceuticals, and food research for concentration, purification, and solvent recovery.
A Lube Oil Tester is a device used to check the condition and quality of lubricating oil in engines and machines. It helps detect issues like contamination, wear metals, water content, and viscosity changes, ensuring proper lubrication and preventing equipment damage. Regular oil testing helps extend machinery life and reduce maintenance costs.
A UV-Vis Spectrophotometer is an analytical instrument used to measure the absorbance or transmittance of a sample in the ultraviolet (UV) and visible (Vis) light spectrum (typically 190–800 nm). It is widely used to determine the concentration of substances in solution based on Beer-Lambert’s Law.
A fat analyzer is a laboratory instrument used to determine the fat content in food and feed samples. It typically operates using solvent extraction methods like Soxhlet or automated systems. The analyzer extracts fat from the sample, then measures and calculates the percentage of fat present. It’s essential in quality control, nutrition labeling, and food research.
The Kjeldahl apparatus is used to determine the nitrogen content in organic compounds, which helps estimate protein levels in food, feed, and other samples. The process involves digestion, distillation, and titration. In digestion, nitrogen is converted to ammonium sulfate; during distillation, ammonia is released and captured; titration quantifies nitrogen. It’s widely used in agriculture, food, and environmental labs.
An incubator is a laboratory device used to maintain a controlled environment with specific temperature, humidity, and sometimes COâ‚‚ levels. It is essential for the growth of microorganisms, cell cultures, and eggs in biological and medical research. Incubators ensure stable conditions for experiments requiring consistent incubation over a set period.
A Flash Point Tester is an instrument used to determine the flash point of a liquid—the lowest temperature at which it emits enough vapor to ignite in air when exposed to an ignition source. This property is critical for assessing the flammability and fire hazard of fuels, solvents, oils, and other chemicals.
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.
An HPLC column (High-Performance Liquid Chromatography column) is a crucial component of an HPLC system used to separate, identify, and quantify components in a liquid sample.
A laboratory chiller is a cooling device used to maintain a constant low temperature for laboratory instruments or processes. It works by circulating chilled fluid (like water or glycol) through equipment such as rotary evaporators, condensers, lasers, or reactors to dissipate heat.
A colorimeter is a device used to measure the concentration of colored compounds in a solution by detecting the amount of light absorbed. It works on Beer-Lambert’s law and is widely used in chemistry, biology, and environmental labs. Colorimeters help in water testing, food analysis, and clinical diagnostics for quick, accurate color-based measurements.
