Ohaus EXR224N Analytical Balance with 220 g Capacity and 0.1 mg Readability
Product Description
The Ohaus EXR224N Analytical Balance delivers precise measurements with a maximum capacity of 220 g and a readability of 0.1 mg, ideal for molecular diagnostics, biotechnology, and bioprocessing applications requiring accurate quantitative analysis. Its 7-inch TFT color touchscreen with glass overlay enhances user interaction and visibility of data during workflows such as basic weighing, parts counting, check weighing, formulation, and density determination.
Key technical features include:
- Internal AutoCal™ calibration ensures consistent accuracy without manual adjustments, critical for reproducible results in biomanufacturing and synthetic biology research.
- Robust metal housing with a SST 316 stainless steel 90 mm × 90 mm weighing pan and an anti-static glass draftshield optimizes weighing stability in controlled laboratory environments.
- Advanced connectivity options: USB Host (Type A) × 2, USB Device (Type C) × 1, Ethernet (RJ45), RS232 port, and optional Wi-Fi/Bluetooth dongle support integration into laboratory information management systems (LIMS) and facilitate remote data monitoring and acquisition.
- Design features such as time synchronization via NTP, 4-level user management, and internal logging for up to 100,000 entries support compliance and traceability requirements in regulated settings.
- Weighing modes cover dynamic and complex tasks, including dynamic weighing, totalization, peak hold, and differential weighing, enabling flexibility in clinical diagnostics and cell imaging sample preparation.
- The device is NTEP Certified and legal for trade, suitable for regulated quality control and manufacturing labs.
This analytical balance is essential for high-precision weighing tasks in biotechnology research, particularly in molecular cloning workflows and biopharmaceutical production pipelines that demand stability and traceable measurement accuracy. The combination of versatile communication protocols and user-friendly operation makes it a popular choice among clinical laboratory professionals and research scientists focusing on synthetic biology and molecular diagnostics.
