Ohaus Semi-Micro Balance EXP125D/AD Precision Analytical Balance with AutoCal™ and Touchscreen
Product Description
The Ohaus Semi-Micro Balance EXP125D/AD is a high-precision weighing instrument ideal for biotechnology, molecular diagnostics, and synthetic biology laboratories requiring accurate mass measurements and repeatable results. This semi-micro analytical balance features a maximum capacity of 82 g/120 g with an exceptional readability of 0.01 mg and 0.1 mg, enabling precise quantification critical in bioprocessing and molecular cloning workflows.
Key technical features include:
- 7-inch TFT 16.7 million color touchscreen with glass overlay for intuitive operation and clear data visualization.
- AutoCal™ internal automatic calibration ensures consistent accuracy essential for critical applications such as gene editing and biomanufacturing.
- Versatile weighing modes supporting basic weighing, parts counting, check/count weighing, percent weighing, formulation, density determination, and dynamic weighing—widely used in quality control and formulation studies within biotechnology and pharmaceutical research.
- Robust modular construction with a metal base, zinc alloy weighing pan (80 mm x 80 mm), and an anti-static glass draft shield for reliable measurements in controlled lab environments.
- Advanced safety and convenience features such as anti-pinch automatic doors, built-in ionizer to neutralize static charge, motorized leveling, touchless sensors, and sample spotlight facilitating precise sample handling and contamination control.
- Comprehensive communication ports including USB Host (Type A) x 2, USB Device (Type B and C), Ethernet (RJ45), RS232, with optional Wi-Fi and Bluetooth dongle, enabling integration with laboratory information management systems (LIMS) and automated bioprocessing data workflows.
- Support for time synchronization via NTP, HID connection without drivers, multi-level user management, and an internal system log capacity of 100,000 entries to ensure traceability and compliance in regulated environments.
- Measures in diverse units including grams, milligrams, carats, and custom units facilitating cross-application flexibility in biomedical engineering, molecular biology, and clinical diagnostics.
- Stabilization time of 5 seconds, repeatability typically 0.1 mg, and minimum weighing capability down to 2 mg, making the balance suitable for sensitive weighing tasks in synthetic biology and biopharmaceutical production pipelines.
This semi-micro balance is an essential tool for laboratories focused on precision weighing tasks in biotechnology research, bioprocessing, and molecular analyses, delivering reliability and advanced connectivity for streamlined workflows.
