Its 420 g capacity handles larger sample sizes without sacrificing the enclosure that milligram-level weighing requires. External calibration is the deliberate design choice here: laboratories operating under certified quality management systems use traceable reference masses on audit-ready schedules, and this balance accommodates that discipline without compromise. The 5.7-inch VGA touchscreen provides access to 15-plus built-in applications including pipette adjustment, density determination, differential weighing, and ingredient costing. The compact draftshield housing (393 × 350 × 230 mm) keeps bench footprint manageable, and the 1-second stabilization time keeps per-sample throughput high despite the fine resolution.\u003c\/p\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eGemological weighing of multi-stone lots and larger precious-metal pieces\u003c\/li\u003e\n  \u003cli\u003ePharmaceutical active ingredient dispensing and in-process weight checks\u003c\/li\u003e\n  \u003cli\u003eAcademic and analytical research requiring draft-protected milligram weighing at broader capacity\u003c\/li\u003e\n  \u003cli\u003eCertified commercial weighing of precious materials with documented calibration records\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy Choose the OHAUS EX423N\/E?\u003c\/h3\u003e\n\u003cp\u003eFor gemologists, pharmaceutical analysts, and quality chemists who need 0.001 g resolution over a wider range than typical milligram balances offer, the OHAUS EX423N\/E Precision Balance combines extended 420 g capacity with draftshield protection and NTEP certification.
