OHAUS EXP623/AD Explorer EXP Precision Balance, 620 g Capacity, 1 mg Readability, AutoCal, Touchscreen

OHAUS EXP623/AD Precision Balance — 620 g Capacity in an Enclosed 1 mg Draftshield Configuration

The OHAUS EXP623/AD Precision Balance takes milligram precision to a 620 g capacity—the widest enclosed-chamber 1 mg range in the Explorer EXP precision series. Pharmaceutical manufacturers, cosmetic producers, and food scientists who routinely work with large vessel tare weights or heavy multi-ingredient formulations can now maintain 1 mg accuracy in a fully protected weighing environment without sacrificing the capacity they need.

Key Features

• 620 g / 1 mg Enclosed Weighing: The broadest milligram-precision range in the enclosed EXP precision series, providing draftshield protection at capacities previously available only in open-pan instruments.
• Built-In Ionizer: Continuously neutralizes electrostatic charge buildup on the stainless steel pan and sample vessel—particularly important when weighing powders, granules, and hygroscopic materials at 1 mg resolution.
• AutoCal Automatic Internal Calibration: Automatic temperature-triggered self-calibration keeps measurements traceable without operator-initiated calibration routines.
• Anti-Pinch Motorized Autodoors: Smooth, electrically actuated draftshield panels open via proximity sensors, enabling clean-hands access and consistent airflow protection.
• 130 × 130 mm Stainless Steel Pan: Accommodates standard weighing boats, sample cups, and small beakers within the enclosed chamber without crowding.
• 1.5-Second Stabilization: Efficient settling at 1 mg readability keeps productivity high in dispensary and formulation applications with many samples per session.
• Regulatory Documentation Support: Four-level user management, NTP time synchronization, and a 100,000-entry system log underpin GMP, ISO, and pharmacopoeial compliance requirements.

Detailed Overview

The OHAUS EXP623/AD Precision Balance removes the trade-off between milligram accuracy and capacity in enclosed configurations. At 620 g, it comfortably handles the combined mass of a typical 250 mL glass beaker plus its contents while weighing the sample mixture to 1 mg. Linearity of ±2 mg and a 1 mg typical repeatability maintain consistent performance from the minimum practical sample weight (0.14 g; USP threshold 1.4 g) to full capacity. The balance shares the same modular Explorer EXP architecture, 7-inch touchscreen interface, and connectivity infrastructure as its siblings—ensuring that method transfer between EXP instruments within a facility involves minimal retraining. Optional Wi-Fi and Bluetooth dongles extend wireless LIMS integration where cabling is impractical.

Applications

• Pharmaceutical dispensing of large-batch formulations at milligram accuracy
• Cosmetic and personal care manufacturing with heavy base phase weighing
• Food and beverage flavor or additive formulation requiring precise milligram control
• Nutraceutical blending where large vessel mass would exceed smaller balance ranges
• Analytical chemistry gravimetric work with larger reaction vessels

Why Choose the OHAUS EXP623/AD?

Formulation and dispensary teams that have worked around capacity limitations by switching to open-pan instruments—and accepting the loss of enclosed-chamber protection—will find the EXP623/AD a direct solution. Maximum capacity and full draftshield protection at 1 mg readability, combined with the compliance features of the EXP platform, make this a specialist instrument that earns its place. Order today and weigh confidently at any load within the 620 g range.
