Ohaus Precision Balance EXP2202 - High-Accuracy Analytical Laboratory Balance
Product Description
The Ohaus Precision Balance EXP2202 is a high-accuracy analytical balance designed for versatile laboratory applications including basic weighing, parts counting, density determination, and formulation workflows essential in biotechnology, molecular diagnostics, and bioprocessing environments.
- Capacity & Readability: Offers a maximum capacity of 2,200 g with a fine readability of 0.01 g, suitable for precise mass measurements in biopharmaceutical production pipelines.
- Weighing Modes: Supports diverse functions such as check weighing, dynamic weighing, percent weighing, pipette adjustment, and flow rate control facilitating synthetic biology and molecular cloning workflows.
- Display & Interface: Features a 7-inch TFT 16.7M color touch screen with glass overlay for intuitive operation and visibility. Communication ports include USB Host (Type A) x 2, USB Device (Type B and C), Ethernet RJ45, RS232, with optional Wi-Fi and Bluetooth dongle for seamless data integration in laboratory information management systems (LIMS).
- Construction & Design: Robust modular design with metal base and housing, stainless steel (SST 316) weighing pan, motorized leveling system, anti-static glass draft shield, built-in ionizer, automatic doors with anti-pinch safety, and touchless sensors that optimize cleanroom compliance and sample integrity.
- Calibration & Accuracy: AutoCal™ automatic internal calibration ensures consistent accuracy; linearity tolerance is ±0.02 g; typical repeatability is 0.01 g, critical for molecular diagnostics and quality control labs.
- Legal & Environmental Compliance: NTEP Certified and optimized for operation within 10°C – 30°C and 80% relative humidity non-condensing environments, aligning with clinical diagnostics and biomedical engineering standards.
- Additional Features: Supports time synchronization via NTP, HID support for driverless computer connection, user management with up to 4 levels, and an internal log for 100,000 entries—ideal for regulated environments requiring traceable measurement data.
This precision balance is widely used in biotechnology research, synthetic biology, and biomanufacturing due to its advanced weighing modes, robust construction, and accuracy, making it essential for molecular cloning, live-cell imaging preparations, and bioprocess monitoring.
