Delmer Analytical Balances

Delmer analytical balances are intended for weighing tasks where small mass differences matter, such as analytical sample preparation, reference materials, formulation, laboratory quality control and research. Choose the model by capacity, readability, repeatability, pan dimensions and the performance required by the method.

Model specifications listed

Laboratory applications

• Analytical chemistry and routine sample preparation.
• Weighing reference materials, reagents and small batches where the model's performance meets the method's tolerance.
• Quality-control checks and research workflows requiring repeatable mass measurements.
• Filter and other small-sample weighing where suitable draft protection and accessories are confirmed for the selected model.

Selection and installation

Use a rigid, level, low-vibration bench away from direct airflow, rapid temperature changes and static sources. For fine weighing, allow samples and containers to equilibrate to the weighing environment and follow the prescribed handling procedure. Readability is not a substitute for accuracy or measurement uncertainty; the smallest usable sample mass depends on balance repeatability and the tolerance required by the method.

The listing describes features such as internal calibration, a backlit display and serial data connectivity for the range; confirm which features and interfaces are included on the exact model quotation. For regulated workflows, establish calibration and performance-check intervals in accordance with your quality system. Product descriptions alone do not certify compliance with a pharmacopoeia or regulatory standard.

For model selection, share your sample mass, target tolerance, application, required data interface and destination country with Delmer Group.
