Balances used in the laboratory

Laboratory balances measure the mass of substances using electromagnetic force or the principle of mechanical lever balance, and are used for sample weighing and formulation calculations to ensure measurement accuracy in chemical analysis and material preparation.
Selection
When selecting a balance, it is essential to consider both the weighing range and precision requirements, while also taking into account the impact of environmental vibrations, temperature, and humidity. Additionally, it is important to verify the calibration certificate and the division value parameters, while balancing operational convenience and maintenance costs.

A Comprehensive Guide to Selecting an Electronic Balance
This article introduces the key points for selecting an electronic balance. It provides a detailed list of core parameters such as accuracy class, repeatability, and linearity error, and explains their impact.
Summary of Balance Selection for Different Application Scenarios
This article discusses how to choose a balance based on usage needs. First, you need to understand the basic parameters of a balance, such as its maximum capacity and precision.
Grade classification of balances based on different repeatability indicators
The repeatability of a balance refers to the consistency of multiple weighing results for the same load under identical conditions, which is a key indicator for evaluating the performance of a balance. It is typically expressed as the standard deviation or range, with smaller values indicating greater stability and reliability of the balance.
Selection criteria for linearity error of semi-micro balances
The linearity error of a semi-micro balance refers to the deviation between the actual displayed value and the theoretical value within its weighing range. This indicator directly affects the accuracy of weighing, which is particularly important in scenarios requiring high-precision measurements, such as material analysis or environmental monitoring.
