Ohaus EXP324/AD Analytical Balance with 7" Color Touchscreen and AutoCal™ Internal Calibration

The Ohaus EXP324/AD analytical balance is engineered for high-accuracy weighing applications in biotechnology, clinical diagnostics, and molecular biology research. Featuring a 320 g maximum capacity and 0.1 mg readability, this precision instrument supports critical workflows such as density determination, formulation, parts counting, and pipette adjustment, making it essential for bioprocessing and synthetic biology tasks requiring rigorous measurement control.

Key features include:

• 7-inch TFT 16.7M color touchscreen with glass overlay for intuitive, multifunctional operation and enhanced user experience
• AutoCal™ internal automatic calibration ensuring measurement reliability and optimal performance without manual intervention
• Stainless steel 316 weighing pan (90 mm x 90 mm) designed for durability and easy cleaning in contaminated lab environments
• Advanced communication interfaces including USB Host (Type A) x 2, USB Device (Type B & C), Ethernet TCP/IP, RS232, with optional Wi-Fi and Bluetooth dongles for seamless integration into laboratory information management systems (LIMS) and data acquisition networks
• Modular design with metal base and housing, enhanced safety with anti-pinch automatic doors, anti-static glass draftshield, motorized leveling, built-in ionizer, and dual touchless sensors to minimize environmental disturbances
• Compliance features such as 4-level user management, internal system log with 100,000 entries, time synchronization via NTP, and support for HID device connections enable robust traceability and operational control in regulated laboratory settings
• Multiple weighing modes including percent weighing, dynamic weighing, totalization, peak hold, check counting, and flow rate control, essential for complex analytical protocols in molecular diagnostics and biomanufacturing
• Supports a broad spectrum of units of measurement tailored for global laboratory use, enhancing flexibility for diverse experimental setups

Operating environment parameters include a temperature range of 10°C to 30°C with 80% relative humidity (non-condensing), stabilizing measurements within 2 seconds. The balance weighs 7.8 kg and features an included in-use cover and AC power adapter.

This analytical balance is widely adopted in biotechnology research, particularly valued for its precision in bioprocessing measurement, critical in gene editing workflows and biopharmaceutical production pipelines where accuracy and repeatability (typical 0.1 mg repeatability, linearity ±0.2 mg) are paramount. The integrated ionizer and draftshield reduce static and airflow interference, enhancing measurement stability for sensitive live-cell imaging sample preparations and fluorescence analysis sample quantifications.

Designed for laboratories demanding reliable, traceable, and versatile high-resolution weighing capabilities, the Ohaus EXP324/AD supports essential molecular cloning workflows and synthetic biology research through its multifunctional application range and technical sophistication.
