Ohaus Precision Balance EXP1203/AD | 1,200 g Capacity, 1 mg Readability Analytical Balance
Product Description
The Ohaus Precision Balance EXP1203/AD is a high-performance analytical weighing instrument designed for precision laboratory applications including molecular diagnostics, bioprocessing formulation, and synthetic biology workflows. Featuring a maximum capacity of 1,200 g and an ultra-fine readability of 1 mg, this balance is essential for accurate quantitative measurements and density determination in biotechnology and clinical diagnostics.
Key technical specifications and features include:
- 7-inch TFT 16.7M color touchscreen with durable glass overlay for intuitive operation and clear visibility of data.
- Comprehensive weighing modes such as basic weighing, parts counting, dynamic weighing, percent weighing, check weighing, formulation, totalization, and differential weighing, making it suitable for biopharmaceutical production pipelines and quality control testing.
- Innovative hardware elements including a SST 316 stainless steel weighing pan (130 × 130 mm), motorized leveling, 2 touchless sensors, built-in ionizer, and an anti-static glass draftshield for enhanced stability and reliable results in sensitive biotechnology environments.
- Communications interfaces support USB Host (Type A), USB Device (Type B and C), Ethernet (RJ45), and RS232 ports, with optional Wi-Fi and Bluetooth dongles, enabling seamless integration into laboratory information management systems (LIMS) and automated workflows.
- Safety-focused design with automatic anti-pinch doors, status lights, and modular metal base housing suitable for cleanroom conditions in molecular biology and cell imaging labs.
- Advanced software capabilities including time synchronization via NTP, HID support without need for drivers, multi-level user management, and extensive system log storage (100,000 entries) to ensure compliance and traceability in regulated biomanufacturing environments.
- Supports a wide array of units of measurement critical to international biotechnological research and industrial applications, including grams, milligrams, carats, ounces, and uncommon units like Tael and Momme.
This precision balance delivers rapid stabilization within 1.5 seconds, excellent repeatability of 1 mg, and linearity tolerance of ±2 mg, making it highly reliable for quantitative chemical analysis and sample preparation in biotechnology research. Its robust design coupled with advanced weighing functions makes the Ohaus EXP1203/AD a critical asset for accuracy-demanding laboratories specializing in gene editing, synthetic biology, and molecular cloning workflows.
