NANBEI Is Professional On Providing One-step Solution Of Laboratory Instruments And Equipment
Basic laboratory instruments form the foundation of daily laboratory operations. These instruments are widely used in education, research, quality control and industrial laboratories. For buyers and laboratory planners, understanding their practical use and basic operating considerations helps ensure correct procurement and long-term reliability.
An analytical balance is used for precise mass measurement of samples, reagents and reference materials. It is a critical instrument in chemical analysis, pharmaceutical formulation and research laboratories.
Analytical balances are commonly applied in sample preparation, standard solution preparation and quantitative analysis. High sensitivity and repeatability are essential for accurate results.
During use, the balance should be placed on a stable, vibration-free surface in a controlled environment. Air drafts, temperature changes and improper calibration may significantly affect measurement accuracy. Regular calibration is recommended to maintain performance.
A pH meter is used to measure the acidity or alkalinity of liquids. It is widely applied in water analysis, food testing, chemical processing and environmental monitoring.
This instrument helps laboratories monitor reaction conditions, product quality and environmental compliance. Digital pH meters provide fast and reliable readings for routine testing.
Electrodes should be kept clean and properly stored in electrode solution when not in use. Regular calibration with standard buffer solutions is necessary to ensure accurate measurements.
A spectrophotometer measures the absorbance or transmission of light through a sample to determine concentration or purity. It is commonly used in chemical, biological and environmental laboratories.
Typical applications include quantitative analysis of solutions, water quality testing and biochemical assays. It supports both routine testing and research-level analysis.
Operators should ensure cuvettes are clean and free from scratches. Samples should be free of bubbles and suspended particles to avoid measurement errors.
A centrifuge separates components of a mixture based on density using centrifugal force. It is widely used in biological, medical and chemical laboratories.
Common uses include sample separation, precipitation collection and phase clarification. Centrifuges improve efficiency in sample preparation processes.
Samples should be balanced evenly before operation to prevent vibration and mechanical damage. The centrifuge lid must remain closed during operation for safety.
A laboratory oven is used for drying, heating and thermal treatment of samples. It is commonly applied in material testing, chemical analysis and sample preparation.
Ovens provide controlled temperature environments for moisture removal, sterilization and thermal stability testing.
Users should avoid overloading the chamber to ensure uniform heat distribution. Temperature settings should be verified regularly to maintain accuracy and safety.
A water bath provides gentle and uniform heating for samples that require controlled temperatures. It is widely used in chemical reactions, incubation and sample warming.
Water baths are preferred when direct heating may damage samples or cause uneven temperature distribution.
The water level should be maintained above the heating element, and regular cleaning is required to prevent contamination and scale buildup.
A magnetic stirrer is used to mix liquid samples evenly during chemical reactions or solution preparation. It is commonly found in chemistry and pharmaceutical laboratories.
Stirrers ensure homogeneous mixing, improve reaction efficiency and support accurate titration and preparation processes.
Stirring speed should be adjusted gradually to avoid splashing or vortex formation. Stir bars should be selected according to container size and liquid volume.
An automatic titrator is used to determine the concentration of substances through controlled titration processes. It is widely applied in chemical analysis, water testing and quality control laboratories.
Automatic titrators improve repeatability and reduce human error compared to manual titration. They support various titration methods and endpoint detection techniques.
Regular maintenance of electrodes and burettes is essential. Titrants should be properly prepared and stored to ensure accurate results.
Basic laboratory instruments are essential for daily testing, analysis and research activities. Selecting suitable equipment requires understanding both application requirements and operational considerations.
Nanbei Instrument provides a comprehensive range of basic laboratory instruments designed for stable performance, easy operation and long-term reliability. By choosing the right equipment and following proper usage guidelines, laboratories can improve efficiency, ensure data accuracy and achieve consistent results.
