Ohaus Precision Analytical Balance EXP223N/AD with 220 g Capacity and 1 mg Readability
Product Description
The Ohaus Precision Balance EXP223N/AD is a high-accuracy electronic weighing instrument designed for advanced laboratory applications including basic weighing, parts counting, check weighing, percent weighing, dynamic weighing, and density determination. It features a robust 220 g maximum capacity with a resolution of 1 mg readability, making it indispensable for molecular diagnostics, synthetic biology, and bioprocessing workflows requiring precise mass measurements.
Technical highlights include:
- 7-inch TFT 16.7M color touchscreen with glass overlay for intuitive operation and enhanced user experience in complex research settings.
- AutoCal™ internal automatic calibration ensures consistent accuracy critical in biotechnology and pharmaceutical lab environments.
- Comprehensive communication interfaces including USB Host (Type A x2), USB Device (Type B and C), Ethernet (RJ45), and RS232, with optional Wi-Fi and Bluetooth dongles to facilitate data integration in modern laboratory information management systems (LIMS).
- Modular metal housing with a stainless steel (SST 316) weighing pan featuring motorized leveling and an anti-static glass draftshield to reduce environmental interferences during sensitive measurements.
- Safety-oriented design includes automatic anti-pinch doors with built-in ionizer and sample spotlight, essential for workflows involving small-volume sample weighing in biomanufacturing and clinical diagnostics.
- Extensive application versatility with 3000 predefined sample libraries supporting specialized tasks such as pipette adjustment, statistical quality control (SQC), fill weight variation, flow rate control, and formulation processes.
- User management system supports four access levels and internal log capacity of 100,000 entries, aligning with compliance requirements in regulated biotechnology laboratories.
Additional specifications:
- Pan size: 130 mm x 130 mm
- Stabilization time: 1.5 seconds
- Repeatability: ±1 mg typical
- Linearity: ±2 mg
- Minimum weight (USP, 0.1% typical): 1.4 g
- Operating environment: 10°C – 30°C, 80% RH non-condensing
- Dimensions: 408 mm x 372 mm x 229 mm (LxHxW)
- Net weight: 7.8 kg
- Units of measurement: mg, g, oz, troy oz, carat, grain, pennyweight
This precision balance is widely adopted in biotechnology research, biochemical laboratories, and clinical settings where molecular cloning workflows, synthetic biology research, and biopharmaceutical production pipelines demand reliable, high-precision mass measurements with data integrity and connectivity.
