OHAUS EXP224/AD Explorer EXP Analytical Balance, 220 g Capacity, 0.1 mg Readability, AutoCal, Touchscreen

OHAUS EXP224/AD Analytical Balance — Extended 220 g Range at 0.1 mg Precision

Analytical accuracy doesn't have to stop at 120 grams. The OHAUS EXP224/AD Analytical Balance extends the EXP series' 0.1 mg readability to a 220 g capacity, accommodating larger sample containers and higher-mass preparations without sacrificing resolution. Chemists and pharmacists who routinely work near the upper bound of standard analytical balances will find this model a more forgiving fit for real-world workflows.

Key Features

• 220 g / 0.1 mg Performance: Nearly double the capacity of entry analytical balances while retaining the same tenth-milligram readability demanded by precise laboratory protocols.
• AutoCal Automatic Calibration: Internal calibration responds to thermal drift so that busy labs don't need to pause workflows for manual adjustment.
• Built-In Ionizer with Anti-Static Draftshield: Continuous charge neutralization on the SST 316 pan reduces weighing error caused by electrostatic attraction between vessel and balance.
• Motorized Anti-Pinch Autodoors: Touchless-sensor-operated side doors allow clean, one-handed access and protect delicate samples in environments with even slight air movement.
• Sample Spotlight and Status Lights: Integrated illumination highlights the weighing area; color-coded status indicators confirm stability before the operator records data.
• 7-Inch Color Touchscreen: Wide display area reduces navigation steps, and glass-overlay construction tolerates routine lab cleaning without degrading touch sensitivity.
• GLP/GMP Documentation Support: Four-level user management, NTP time synchronization, and a 100,000-entry system log underpin traceability requirements in regulated facilities.

Detailed Overview

The OHAUS EXP224/AD Analytical Balance serves laboratories that need 0.1 mg resolution on samples too large or dense for a standard 120 g analytical balance. The 2-second stabilization time keeps throughput high despite the extended capacity, and a 100 mg USP minimum weight at 0.1% reflects well-characterized performance across the full range. The 3,000-entry application sample library stores method parameters for recurring procedures, while HID device mode enables the balance to input data directly into connected spreadsheets or LIMS—a practical efficiency gain for high-documentation environments. Accessories such as the anti-static kit, draft shield side panel, and optional wireless dongles can be added to tailor the instrument to specific workflow requirements. The stainless steel pan cleans reliably and resists most common solvents used in routine lab cleaning.

Applications

• Analytical weighing of larger pharmaceutical samples and excipient blends
• Gravimetric determination requiring extended capacity with sub-milligram accuracy
• Calibration laboratory reference standard preparation
• Nutraceutical and cosmetic ingredient weighing
• Research applications involving heavier reaction vessels or dense substrates

Why Choose the OHAUS EXP224/AD?

Laboratories that have outgrown 120 g analytical balances but need to maintain 0.1 mg accuracy will find the EXP224/AD a logical extension rather than a compromise. The same rigorous compliance features and connectivity suite found across the EXP range are fully intact, now paired with a 220 g ceiling. Add to cart to expand your analytical capability without changing your workflow.
