OHAUS EX324N/AD Explorer Analytical Balance, 320g Capacity, 0.1mg Readability, AutoCal, NTEP Certified

OHAUS EX324N/AD Analytical Balance — 320g Precision with Motorized Hands-Free Doors

Hands-free sample loading at the analytical scale is not a luxury—it is a precision requirement. The OHAUS EX324N/AD Analytical Balance combines a 320 g capacity, 0.1 mg resolution, AutoCal internal calibration, and motorized auto doors into one certified instrument, eliminating manual door contact as a source of vibration and thermal disturbance during critical weighing.

Key Features

• Motorized Auto Doors: Sensor-triggered doors open and close without physical contact, preventing hand-induced vibration and temperature changes from entering the weighing chamber—essential when resolving to 0.1 mg (0.0001 g).
• 320g Analytical Capacity: Broader than most 220 g analytical models, the extended range accommodates larger flasks, heavier sample matrices, and buoyancy-correction setups used in density determination.
• AutoCal Internal Calibration: Temperature-triggered automatic recalibration continuously maintains ±0.0002 g linearity, removing calibration pauses from routine analytical workflows.
• NTEP Class I Certified: Legal-for-trade approval at 1 mg certified readability satisfies compliance requirements for pharmaceutical production records, certified weighing services, and regulated research environments.
• 3-Second Stabilization for Reliable Readings: The deliberate settling interval provides fully stable, confirmed results before capture—reducing errors in high-stakes analytical measurements.
• 5.7-Inch Color VGA Touchscreen: Intuitive application access, result display, and communication settings through a large, bright interface—navigable with or without lab gloves.
• USB & RS232 Connectivity: Direct wired output to GLP printers, LIMS, and data-management software; optional Ethernet for network-integrated laboratory workflows.

Detailed Overview

The OHAUS EX324N/AD Analytical Balance differs from the standard EX324N in one operationally significant way: its motorized auto doors transform sample loading from a manual, disturbance-prone step into a controlled, sensor-activated process. For analysts running high-frequency sample sequences—SQC sampling, reference standard verification, or pipette calibration—the reduction in vibration and thermal input translates directly into more consistent repeat readings. AutoCal monitors thermal drift independently and fires the internal calibration weight automatically, so extended measurement sessions maintain accuracy without manual interruption. The 90 mm stainless steel pan and enclosed draftshield provide the stable weighing environment required at 0.0001 g resolution. The 19-unit library, 15-plus application modes, and GLP data output with timestamp support regulatory documentation across pharmaceutical, research, and commercial laboratory settings.

Applications

• High-frequency pharmaceutical QC sampling requiring hands-free sample loading
• Pipette calibration and gravimetric check sequences in analytical chemistry
• Reference-standard comparison and certified mass verification
• Density determination for solid and liquid pharmaceutical samples
