Ohaus Semi-Micro Analytical Balance EXR225D with 7" Color Touchscreen and Multi-Communication Interfaces

The Ohaus Semi-Micro Balance EXR225D is a precision analytical weighing instrument designed for advanced laboratory applications including biotechnology, molecular diagnostics, and bioprocessing. It features a 120 g maximum capacity with high-resolution readability down to 0.01 mg, making it essential for applications requiring exceptional accuracy such as gene editing workflows and synthetic biology research.

Key technical specifications include:

• 7-inch TFT 16.7M color touchscreen with glass overlay for intuitive operation and clear display of weights and functions.
• Versatile weighing modes: Basic Weighing, Parts Counting, Check Counting, Percent Weighing, Check Weighing, Dynamic Weighing, Totalization, Formulation, Differential, Density Determination, and Peak Hold, supporting broad laboratory workflows.
• Robust construction with a metal housing, zinc alloy aeroweighing pan (80 mm x 80 mm), and anti-static glass draftshield ensures stable and reliable measurements, critical for sensitive biomanufacturing environments.
• Advanced communication interfaces: USB Host (Type A) × 2, USB Device (Type C) × 1, Ethernet (RJ45), RS232, plus optional Wi-Fi and Bluetooth connectivity, enabling seamless integration into laboratory information management systems (LIMS) and data collection in molecular biology and clinical diagnostics settings.
• AutoCal™ automatic internal calibration for uninterrupted precision, reducing user intervention and maintaining traceability standards.
• User management with four permission levels and an internal log capacity of 100,000 entries supports compliance in regulated biotechnology labs.
• Supports multiple units of measurement including milligram, gram, carat, Newton, and custom units, providing flexibility for diverse research and production needs.
• Operating environment optimized for stability: 10°C – 30°C and 80% relative humidity non-condensing.
• Stabilization time of approximately 5 seconds and typical repeatability of 0.1 mg meet demands of exact bioprocess parameter quantification.

This balance is widely adopted in biotechnology research for its precision and reliability in molecular cloning workflows, biomanufacturing quality control, and other critical measurement tasks that underpin synthetic biology innovation. Its multi-functional weighing modes and high accuracy make it a cornerstone instrument in analytical laboratories focusing on fluorescence analysis, live-cell imaging preparations, and other life science applications.
