Ohaus Precision Balance EXR2202 with 7-inch Color Touchscreen and Advanced Weighing Functions
Product Description
The Ohaus Precision Balance EXR2202 is a high-accuracy laboratory balance designed for technical applications including basic weighing, parts counting, dynamic weighing, formulation, density determination, and more—making it an essential instrument in biotechnology, molecular diagnostics, and bioprocessing workflows.
Key features include:
- Maximum capacity of 2,200 g with a fine readability of 0.01 g and linearity of ±0.02 g, enabling precise mass measurements necessary in biopharmaceutical production and synthetic biology research.
- A vibrant 7-inch TFT 16.7M color touchscreen with glass overlay enhances user interaction and data visualization.
- Robust communication interfaces including USB Host (Type A), USB Device (Type C), Ethernet (RJ45), and RS232, with optional WiFi and Bluetooth modules, facilitate seamless connectivity and data transfer in laboratory environments focused on molecular cloning and live-cell imaging.
- Constructed with metal housing, a stainless steel (SST 316) weighing pan, and anti-static glass draftshield coupled with touchless sensors to ensure reliable measurements within controlled environments.
- Advanced software features such as Time Synchronization via NTP, HID support for driver-free computer connections, 4-level user management, and a large internal system log (100,000 entries) support high-throughput laboratory workflows and data integrity in compliance with research best practices.
- Supports multiple units of measurement including grams, ounces, carats, and Singapore Tael, suitable for diverse applications across clinical diagnostics and biomanufacturing.
- The balance’s stabilization time of 1 second and typical repeatability of 0.01 g allow rapid, reliable results critical in time-sensitive experiments.
This precision balance is widely adopted in laboratories requiring exact mass determination for synthetic biology, molecular biology, and biotechnology research, with specialized weighing modes supporting complex bioprocessing protocols and formulation accuracy. Its connectivity options and robust design make it well-suited for integration into automated laboratory setups and biomedical engineering applications requiring traceable measurement data.
