Laboratory Balances

Precision, Analytical and Semi-Micro Laboratory Balances

Laboratory balances are used throughout scientific, pharmaceutical, industrial and educational environments where accurate and repeatable weighing is required. At GNW Instrumentation, we supply analytical, precision and semi-micro balances for professional laboratory, research and quality-control applications.

Our range includes laboratory balances from KERN, Ohaus and Adam Equipment, covering different capacities, readabilities, calibration methods and connectivity options. The appropriate balance depends on factors including the sample size, required resolution, operating environment and applicable quality procedures.

Precision balances are commonly used for routine weighing, formulation, sample preparation, education and industrial testing. Depending on the model, they typically provide readabilities from 0.01 g to 0.001 g, together with higher weighing capacities than many analytical balances.

Analytical balances commonly provide 0.0001 g (0.1 mg) readability, allowing much smaller changes in mass to be displayed. They are widely used for analytical chemistry, gravimetric testing, pharmaceutical work and scientific research. Many models incorporate glass draught shields to reduce the effects of air movement during sensitive measurements.

Semi-micro balances provide finer readability for specialist applications involving small sample masses and carefully controlled weighing procedures. They are commonly used in research, pharmaceutical development and other demanding analytical environments.

Selected laboratory balances incorporate automatic internal adjustment, commonly described as internal calibration, using a built-in reference weight. Other models require external adjustment using a suitable calibrated test weight. Available functions vary by model and should be considered alongside the laboratory’s calibration and verification procedures.

Selected models also provide RS-232, USB or formatted GLP/GMP data output for connection to printers and computer systems. These functions can support documented laboratory procedures, data recording and audit readiness, depending on the balance configuration and the organisation’s quality system.

The installation environment can have a significant effect on sensitive weighing. Draught shields, anti-vibration tables and controlled weighing areas can help reduce the influence of air movement, vibration and changing environmental conditions. The level of protection required depends on the readability of the balance and its intended application.

Laboratory balances are used across pharmaceutical manufacturing, food testing, chemical analysis, education, industrial quality control, materials testing and research. Typical applications include sample preparation, formulation, gravimetric analysis, active-ingredient verification and incoming-material inspection.

Calibration certification is available for laboratory balances supplied by GNW Instrumentation. We also provide laboratory-balance calibration services to support ongoing verification, measurement confidence and traceability. Available certificate and calibration options should be confirmed for the selected model.

GNW Instrumentation combines weighing-equipment supply with practical calibration and instrumentation experience developed over decades within the UK measurement industry. Our team can help customers compare capacities, readabilities, adjustment methods and connectivity options when selecting a suitable laboratory balance.

Whether you require a compact precision balance for routine work, an analytical balance for sensitive measurements or a semi-micro balance for more demanding applications, the collection provides options for a wide range of professional laboratory weighing requirements.
