Large display glass touchscreen

The removable control panel with a large, clear, and responsive 7-inch TFT glass display touchscreen, with 800×480 px resolution, offers chemical protection and two customizable status lights, ensuring maximum visibility and simple, safe use. The 80×80 mm Aero stainless steel pan, combined with the anti-static coated draft shield and integrated ionizer, guarantees precision and optimal sample protection. The balance is also equipped with sample illumination using white light and 7-color selectable status lights, all of which further enhance the user experience and productivity in the laboratory. And there’s more: motorized leveling, quick setup, automatic doors with safety system, touchless sensors, and much more!

Compliance and Data Traceability

The EXP series supports regulatory compliance thanks to a 4-level user system, password protection, and internal logging of up to 100,000 events. The NTP time synchronization function ensures data traceability in compliance with pharmaceutical regulations. Communication ports include USB-A, USB-B, USB-C, Ethernet, RS232, with additional options for Wi-Fi and Bluetooth dongle.

Performance and Applications

The EXP Semi-Micro balances offer capacities up to 220 g with resolution down to 0.01 mg and extremely fast stabilization times (≤5 s). Sensitivity is kept stable thanks to integrated environmental sensors for temperature, humidity, and atmospheric pressure.

Applications include:

• Weighing of very small chemical or biological samples.

• Determination of the density of solids and liquids.

• Calibration and adjustment of pipettes and dosing instruments.

• Statistical process control (SQC) and regulated laboratory analysis.

• Dynamic, percentage, and total weighing of components in complex formulations.

• Flow measurements and weight control in delicate filling and industrial processes.

Used in:

• Chemical, pharmaceutical, and biotechnological laboratories.

• Academic and industrial research centers.

• Quality control laboratories and regulated production (GMP/GLP).

• Metrology laboratories and instrument calibration.

• Industrial environments or pilot plants that require ultra-precise weighing.

Legend:

• D (Dual Range): indicates that the balance has a dual resolution: a finer one for small weights (Fine Range) and a less fine one for larger weights (Full Range). For example, 0.01 mg for small weights and 0.1 mg for larger weights. Not certified for commercial use.

• DM (Dual Range + Verification): same as the D model, but Class I certified for commercial use and features a verification interval (e) in accordance with legal metrology regulations.

• M (Verification): single high resolution (e.g. 0.01 mg) and Class I certified for commercial use, with a defined verification interval. These models are ideal for regulated laboratories where legal compliance and data traceability are required.

• The abbreviation “AD” indicates that the model is equipped with Advanced Display: remote color touchscreen with touchless sensors, sample illumination, customizable status lights, and quick controls for tare, printing, and other operations.
