Ohaus Precision Balance EXR2202N – 2,200g Capacity with 0.01g Readability, Touchscreen Interface
Product Description
The Ohaus Precision Balance EXR2202N is a high-accuracy laboratory weighing instrument designed for versatile use in molecular diagnostics, bioprocessing, and biotechnology research. It supports a maximum capacity of 2,200 grams with an excellent resolution of 0.01 grams, making it suitable for precise formulation, parts counting, and density determination tasks critical in synthetic biology and biomanufacturing workflows.
Key technical features include:
- Display & Interface: Large 7-inch TFT 16.7M color capacitive touchscreen with glass overlay ensures intuitive operation and clear data visualization essential for reliable weight analysis.
- Communication Ports: Multiple USB hosts (Type A x2), USB device (Type C), Ethernet (RJ45), RS232, with optional Wi-Fi and Bluetooth connectivity, allowing seamless integration into laboratory data systems and real-time data logging for clinical diagnostics and biomedical engineering applications.
- Construction & Durability: Robust metal housing, stainless-steel (SST 316) weighing pan, and anti-static glass draft shield minimize environmental interference, enhancing measurement stability in controlled lab environments.
- Operation & Calibration: Features AutoCal™ automatic internal calibration for consistent accuracy and minimal user intervention, vital in rigorous biotech research and quality control.
- Advanced Functionality: Supports 1,000 application-specific sample libraries and includes features such as time synchronization (NTP), 4-level user management, and an internal system log capacity of 100,000 entries, ensuring compliance and traceability in molecular cloning and synthetic biology labs.
- Measurement Versatility: Supports multiple units of measurement (g, oz, ct, lb, troy, pennyweight, grain), dynamic weighing, totalization, peak hold, and differential weighing modes essential for complex bioprocessing protocols.
Dimensions are 391 mm x 95 mm x 229 mm (L x H x W), weighing approximately 4.9 kg, with operational environment specifications of 10°C to 30°C, 80% relative humidity (non-condensing). The balance is NTEP certified for legal-for-trade applications.
This precision balance is widely used in synthetic biology research and biopharmaceutical production pipelines where accurate weight measurement directly impacts experimental reproducibility and bioprocess quality. Its advanced communication features and rugged design make it an essential instrument for molecular biology workflows, gene editing labs, and live-cell imaging preparations requiring precise reagent formulations.
