The Ohaus EXP12202N Precision Balance is designed for rigorous laboratory weighing tasks including basic weighing, parts counting, percent and check weighing, dynamic weighing, totalization, formulation, density determination, and pipette adjustment. Its 12,200 g maximum capacity with a 0.01 g readability ensures precise measurement suitable for pharmaceutical, biotechnology, and molecular diagnostics workflows.
Key technical features include a 7-inch TFT 16.7M color touchscreen with a glass overlay, promoting ease of use in live-cell imaging and bioprocessing environments requiring accurate weight measurements. Communication options are comprehensive, incorporating USB Host Type A (x2), USB Device Types B and C, Ethernet (RJ45), RS232, and optional Wi-Fi and Bluetooth dongles, facilitating seamless integration into laboratory information management systems (LIMS) and networked biomanufacturing setups.
The balance's modular design features a metal base and housing with a stainless steel (SST 316) weighing pan, motorized leveling, two touchless sensors, status lights, and an anti-static glass draftshield. Safety is enhanced with automatic doors featuring anti-pinch protection. Built-in ionizer and sample spotlight are included for 1 mg readability models, supporting critical workflows in synthetic biology and molecular cloning requiring contamination control and stable environmental conditions.
Additional specifications:
This precision balance is widely used in biotechnology research, pharmaceutical quality control, synthetic biology experimentation, and biomanufacturing processes requiring reliable, high-accuracy weighing performance critical to molecular diagnostics and gene editing protocols. Its advanced connectivity, modular construction, and comprehensive application library make it essential for laboratories prioritizing scalable and traceable measurement standards.
