Ohaus Precision Balance EXR223 Analytical Balance with 7" Color Touchscreen and AutoCal™
Product Description
The Ohaus Precision Balance EXR223 is a high-accuracy analytical balance designed for advanced laboratory weighing tasks critical in biotechnology, molecular diagnostics, and bioprocessing workflows. Featuring a maximum capacity of 220 g and a readability of 1 mg, the EXR223 ensures precise measurements essential for formulation, density determination, and parts counting applications widely adopted in synthetic biology research.
Key technical features include:
- 7-inch TFT 16.7M color touchscreen display with glass overlay for intuitive navigation and clear data visualization.
- Multiple weighing modes such as Basic Weighing, Parts Counting, Check Counting, Percent Weighing, Dynamic Weighing, Totalization, Differential, Density Determination, and Peak Hold, enabling versatile lab workflows.
- Robust communication interfaces: USB Host (x2), USB Device (Type C), Ethernet (RJ45), RS232, with optional Wi-Fi and Bluetooth dongles for seamless connectivity in laboratory information management systems (LIMS) important in biomanufacturing environments.
- Durable construction with metal housing, SST 316 stainless steel weighing pan (130 mm x 130 mm), and an anti-static glass draft shield with 2 touchless sensors to minimize environmental interference.
- Advanced usability features such as AutoCal™ internal automatic calibration, time synchronization via NTP, 4-level user management, and a 100,000-entry system log facilitate compliance and traceability in regulated biopharmaceutical production pipelines.
- Supports a wide range of units including grams, milligrams, carats, taels, ticals, and ounces supporting international laboratories and specialized biotech measurements.
Operating conditions are optimized for controlled lab environments (10°C–30°C, 80% RH non-condensing) with a rapid stabilization time of 1.5 seconds and excellent repeatability at 1 mg, attributes indispensable for live-cell imaging preparations, molecular cloning quantifications, and clinical diagnostics.
This precision balance is an essential instrument for laboratories focused on molecular biology, cell imaging, and fluorescence analysis, providing reliable, high-resolution weighing data that underpin critical processes in gene editing and bioprocessing. Its modular connectivity and robust design make it a popular choice among researchers demanding accuracy and efficiency in their analytical balance for biomedical engineering and synthetic biology experiments.
