Digital Analytical Balance – 0.1 mg Readability

The ALC-SCIENTIFIC Digital Analytical Balance is designed for high-precision mass measurement of laboratory samples, chemicals, standards and formulations. The primary reference configuration offers 0.1 mg or 0.0001 g readability and uses an enclosed glass draft shield to reduce the influence of air movement on sensitive measurements. The balance is suitable for pharmaceutical quality control, analytical chemistry, biotechnology, food testing, diagnostic laboratories, universities and industrial research facilities. Depending on the selected model, it may include internal or external calibration, multiple weighing applications, data connectivity and level monitoring. Final capacity, repeatability, linearity and minimum-weight performance are to be confirmed for the selected model.

• Reference readability of 0.1 mg or 0.0001 g for high-resolution laboratory weighing.
• Enclosed glass draft shield designed to reduce measurement disturbance caused by air currents.
• Electromagnetic force-compensation weighing technology, subject to final model confirmation.
• Digital display for clear presentation of weight, stability and operating information.
• Tare and zero-setting functions for routine sample and container weighing.
• Internal automatic or external calibration options, depending on the selected configuration.
• Adjustable levelling feet with bubble or electronic level guidance, model-dependent.
• Stainless-steel weighing pan designed for routine laboratory cleaning and sample handling.
• Multiple weighing units and application programs available in selected configurations.
• RS232, USB or Ethernet connectivity available according to the selected model.

A high-resolution electronic analytical balance generally operates through electromagnetic force compensation. When a sample is placed on the weighing pan, its gravitational force produces a small displacement within the weighing mechanism. The control system generates an opposing electromagnetic force that returns the mechanism to its reference position. The electrical current required to create this balancing force is measured and converted into the displayed mass value. Correct levelling, calibration and environmental control are essential because airflow, vibration, temperature variation and local gravity can influence sensitive weighing results.

• Mechanical or electronic overload protection, subject to model design.
• Stability indication before recording or transferring a weighing result.
• Levelling indication to reduce installation-related weighing error.
• Calibration reminder or adjustment status where provided by the selected model.
• Error messages for overload, underload, unstable conditions or incorrect operation.
• Grounded power adaptor or approved low-voltage supply, according to the selected model.

Final ALC-SCIENTIFIC model codes, repeatability, linearity, dimensions and calibration systems: To be confirmed.

Accessory compatibility must be confirmed against the selected model.

• Clean the weighing pan after use with a soft brush, lint-free cloth or compatible laboratory cleaning material.
• Remove powder and chemical residue without allowing material to enter the weighing mechanism.
• Clean glass draft-shield panels using a compatible laboratory cleaner.
• Do not apply excessive force to the weighing pan or internal weighing cell.
• Check levelling before critical weighing procedures.
• Perform routine verification using suitable certified reference weights.
• Calibrate or adjust the balance according to the laboratory quality procedure.
• Record calibration, verification, preventive maintenance and repair activities.
• Inspect the power adaptor, communication ports and draft-shield doors periodically.
• Recalibrate after relocation, major repair or significant environmental change.
