Analytical Balance

Pruiste is a analytical balance factory in china, the analytical balance is a high-precision electronic or mechanical balance used for laboratory precision weighing, with a weighing accuracy typically reaching 0.1 milligrams (0.0001 grams) or even higher. It is widely used in fields such as chemistry, biology, pharmaceuticals, and materials science, and is an indispensable instrument in quantitative analysis experiments.

Core Features of analytical balance

1. High precision and sensitivity: By using electromagnetic force compensation or precision lever principle, it can detect trace changes in mass, and some models support a resolution of one millionth of a gram (0.001 mg).
2. Environmental adaptability: Equipped with a windproof cover (dust-proof and anti airflow interference), temperature compensation system, and some models have anti vibration function to ensure weighing stability.
3. Multifunctionality: Supports multiple weighing modes (such as dynamic weighing, percentage weighing, density measurement), and can be connected to a computer through software for data recording and analysis.

Working principle of analytical balance

1. Electronic analytical balance: Based on the principle of electromagnetic force balance, the sample mass is converted into an electrical signal output, which is calculated and displayed in real time by sensors and microprocessors.
   
2. Mechanical analytical balance (rarely seen): Based on the principle of lever balance, precise measurement is achieved through weight and weight adjustment.

Main types of analytical balance

1. Semi micro balance: The range is usually 100-200 g, with an accuracy of 0.01 mg.
2. Microbalance: With a small range (≤ 30 g) and an accuracy of up to 0.001 mg, it is suitable for ultra trace samples.
3. Ultra microbalance: with a range of only a few grams and a resolution of up to 0.1 µ g, it is used for the research and development of nanomaterials or drugs.

Precautions for uses

1. Calibration: It is necessary to regularly use standard weights for external calibration or activate the built-in automatic calibration function.
2. Environmental control: Avoiding temperature fluctuations, airflow, and static interference, horizontal adjustment is crucial.
3. Operation standard: Handle the sample gently to prevent overload; Corrosive substances need to be stored in containers.

Application scenarios

1. Pharmaceutical industry: raw material weighing and formula development.
2. Environmental monitoring: Analysis of atmospheric particulate matter quality.
3. Research experiment: synthesis of nanomaterials, cell culture weighing.

The analytical balance as the "precision eye" of modern laboratories, continues to push the boundaries of scientific research with its technological advancements. In the future, with the integration of artificial intelligence and automation technology, analytical scales will further improve efficiency and accuracy, becoming one of the core equipment in intelligent laboratories.
