Ohaus EXP125/AD Semi-Micro Balance with AutoCal™ and 7" Color Touchscreen
Product Description
The Ohaus EXP125/AD Semi-Micro Balance is engineered for high-precision weighing applications essential in biotechnology, molecular diagnostics, and bioprocessing workflows. This analytical precision scale features a maximum capacity of 120 g with 0.01 mg readability and typical repeatability of 0.02 mg, enabling accurate measurement critical for synthetic biology and formulation research.
Key technical features include:
- 7-inch TFT 16.7M color touchscreen for intuitive operation and enhanced user interface
- AutoCal™ internal automatic calibration ensures precise and reliable measurements without external weights
- Anti-static glass draftshield and zinc alloy pan (80 mm x 80 mm) designed to minimize environmental interference and improve accuracy
- Modular metal housing with motorized leveling and built-in ionizer for stability and contamination control in sensitive laboratory environments
- Advanced communication ports including USB Host (Type A) x2, USB Device (Types B and C), RS232, Ethernet, with optional Wi-Fi and Bluetooth dongles for seamless data integration into biomanufacturing and clinical diagnostic systems
- Operational versatility with multiple weighing modes: basic weighing, parts counting, check weighing, percent weighing, density determination, formulation, dynamic weighing, and pipette adjustment, making it widely used in molecular cloning and pharmaceutical production pipelines
- Supports HID human interface device protocol for driverless computer connectivity and includes 4-level user management with extensive system logs, ideal for regulated lab environments requiring traceability
Environmental and physical specifications:
- Operating temperature range of 10°C to 30°C (50°F to 86°F), 80% RH non-condensing suitable for controlled lab conditions
- Compact footprint: 408 mm x 372 mm x 229 mm; net weight of 7.8 kg
- Equipped with safety anti-pinch automatic doors and sample spotlight enhancing usability and operator safety
This semi-micro balance is critical in biotechnology research, providing reliable mass measurement essential for applications such as live-cell imaging protocols, bioprocess optimization, gene editing experiments, and synthetic biology assays. Its high-resolution weighing capabilities and versatile application support make it indispensable for molecular biology researchers and clinical labs focused on precision bioanalysis and biomanufacturing quality control.
