Ohaus EXR324N Analytical Balance with 0.1 mg Readability and Multi-Interface Connectivity
Product Description
The Ohaus EXR324N analytical balance delivers high-precision weighing essential for molecular diagnostics and biotechnological workflows such as bioprocessing and synthetic biology research. It features a maximum capacity of 320 g and a high readability of 0.1 mg, supporting applications including basic weighing, parts counting, percent weighing, and density determination.
Key technical features include:
- 7-inch TFT 16.7M color touchscreen with glass overlay for intuitive operation and enhanced visibility in laboratory environments.
- Robust construction with a metal housing, SST 316 stainless steel weighing pan (90 mm x 90 mm), and an anti-static glass draftshield to ensure stable measurements critical in clinical diagnostics and biomanufacturing.
- Advanced communication capabilities with USB Host (Type A) x 2, USB Device (Type C), Ethernet (RJ45), and RS232 ports; optional Wi-Fi and Bluetooth dongles enhance connectivity for integration in automated molecular biology laboratories.
- Supports multiple weighing units, including milligram, gram, ounce, carat, and grain, enabling versatility across various research fields.
- Internal AutoCal™ automatic calibration maintains accuracy without manual intervention.
- Fast stabilization time of 2 seconds optimizes throughput in high-volume biomanufacturing and cell imaging workflows.
- Comprehensive software features such as time synchronization (NTP), HID support for driverless computer connection, four-level user management, and a system log with 100,000 entries, supporting stringent data integrity requirements in biomedical engineering.
- Certified compliant for trade (NTEP) and equipped with accessories such as an auxiliary display and anti-vibration designs to ensure reproducibility in sensitive analyses.
This precision analytical balance is widely adopted in molecular biology laboratories for essential weighing tasks in molecular cloning workflows, gene editing sample preparation, and critical quantitative analyses in synthetic biology research. It excels in environments requiring accurate weight determination and stable performance, making it an indispensable tool across biotechnology, clinical diagnostics, and biomedical engineering sectors.
