Resolving mass to 0.01 mg (10 µg) across a generous 220 g maximum capacity, this instrument supports the full spectrum of pharmaceutical, chemical, and research workflows — from trace-level sample characterization to multi-gram compound synthesis — all from a single device equipped with automatic calibration.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e0.01 mg Readability at 220 g Capacity:\u003c\/strong\u003e Extended semi-micro range allows heavier samples to be weighed at 10 µg resolution, reducing the need to switch between instruments mid-protocol.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAutoCal™ Automatic Internal Calibration:\u003c\/strong\u003e Motorized internal weight engages whenever thermal drift is detected, maintaining 0.01 mg accuracy without scheduled calibration interruptions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosed Anti-Static Glass Draftshield:\u003c\/strong\u003e Fully sealed 80 × 80 mm weighing chamber eliminates airflow and electrostatic effects that degrade readings at microgram sensitivity.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e7-inch TFT Touchscreen with Touchless Sensors:\u003c\/strong\u003e Proximity-activated taring reduces mechanical disturbance near the balance, protecting sensitive measurements from inadvertent interference.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWired Connectivity Standard:\u003c\/strong\u003e USB Device, two USB Host ports, RS232, and Ethernet accommodate printers, PCs, and LIMS; wireless expansion via optional dongle.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1,000-Sample Library:\u003c\/strong\u003e Stores reference masses for frequently repeated tasks, reducing setup time in high-throughput micro-weighing environments.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRegulatory-Compliance Tools:\u003c\/strong\u003e Four-level user management, 100,000-entry audit log, and NTP timestamps address data integrity requirements in regulated workflows.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDetailed Overview\u003c\/h3\u003e\n\u003cp\u003eThe EXR225 pushes the semi-micro class further than most instruments in its segment by combining an unusually wide 220 g capacity with 0.01 mg resolution on a single range. This breadth is particularly valuable in pharmaceutical development, where a single preparation might involve a weigh-boat plus a multi-gram compound plus a micro-quantity additive — all measured on the same instrument. The 80 × 80 mm stainless-steel pan fits small vessels and weigh boats typical in semi-micro work. Metal housing sustains calibration stability across a full laboratory day, and the 10°C–30°C operating range covers standard climate-controlled settings. The Explorer EXR platform's HID functionality allows direct computer connection without driver installation, streamlining lab IT management considerably.\u003c\/p\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003ePharmaceutical compound synthesis where both micro-quantity additives and larger base masses appear in the same batch\u003c\/li\u003e\n  \u003cli\u003eTrace impurity and residue analysis in environmental and food safety testing\u003c\/li\u003e\n  \u003cli\u003eHigh-precision density determination of compounds with high molar mass\u003c\/li\u003e\n  \u003cli\u003eAdvanced materials research requiring microgram accuracy across gram-scale samples\u003c\/li\u003e\n  \u003cli\u003eReference material certification requiring the widest possible mass range at 0.01 mg resolution\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy Choose the OHAUS EXR225?\u003c\/h3\u003e\n\u003cp\u003eThe OHAUS EXR225 Semi-Micro Balance eliminates the common trade-off between semi-micro precision and usable capacity.
