Ohaus EXP224/AD Analytical Balance with 0.1 mg Readability and Multi-Function Weighing Capabilities
Product Description
The Ohaus EXP224/AD analytical balance delivers precise weighing with a maximum capacity of 220 g and a readability of 0.1 mg, optimized for applications in biotechnology, molecular diagnostics, bioprocessing, and clinical laboratory workflows. This balance supports advanced functions such as basic weighing, parts counting, check counting, percent weighing, dynamic weighing, totalization, formulation, differential weighing, density determination, and pipette adjustment—making it essential for synthetic biology research and biopharmaceutical production pipelines.
Key technical features include:
- 7-inch color TFT touchscreen with 16.7 million colors and glass overlay for intuitive user interaction.
- Modular construction with a metal base and 316 stainless steel weighing pan ensures durability in biomedical engineering environments.
- Enhanced automatic anti-pinch draftshield doors with anti-static glass and built-in ionizer minimize sample contamination and environmental interference.
- Fast stabilization time of 2 seconds with repeatability of 0.1 mg and linearity ±0.2 mg supports high-precision measurements critical for molecular cloning workflows.
- Extensive communication interfaces: USB Host (Type A) x2, USB Device (Type B & C), Ethernet RJ45, and RS232, with optional Wi-Fi and Bluetooth dongles for connectivity in modern biomanufacturing laboratories.
- Supports multiple units of measurement relevant across international research including milligrams, grams, carats, and many region-specific units.
- Advanced features such as Time Synchronization NTP, HID support for driver-free computer connectivity, 4-level user management, and an internal system log with 100,000 entries enhance compliance and traceability in regulated environments.
- Suitable for use in controlled environments between 10–30 °C with 80% relative humidity, ensuring stable performance in laboratory conditions involving live-cell imaging and fluorescence analysis.
- Auxiliary display and in-use cover available as accessories to support ergonomic use in busy lab settings.
This analytical balance is widely adopted in biotechnology labs for tasks requiring precise and repeatable weighing, making it a critical instrument in molecular diagnostics, gene editing experiments, and bioprocess monitoring. The Ohaus EXP224/AD supports the accurate measurements necessary for complex experimental protocols and formulation tasks within synthetic biology and biomanufacturing workflows.
