OHAUS EXP125/AD Explorer EXP Semi-Micro Balance, 120 g Capacity, 0.01 mg Readability, AutoCal, Touchscreen

OHAUS EXP125/AD Semi-Micro Balance — 0.01 mg Resolution for Exacting Research

When routine analytical precision is simply not fine enough, the OHAUS EXP125/AD Semi-Micro Balance steps in with 0.01 mg readability across a 120 g range. Designed for applications where microgram-level differences matter—such as active pharmaceutical ingredient weighing or trace microanalysis—this balance pairs razor-sharp resolution with a 5-second stabilization time suited to controlled laboratory environments.

Key Features

• 0.01 mg Readability: Resolves weight changes down to ten micrograms, enabling accurate measurement of very small sample masses.
• AutoCal Automatic Calibration: Temperature-triggered internal calibration compensates for laboratory thermal fluctuations without requiring operator action.
• Built-In Ionizer: Eliminates static charge buildup on the zinc-alloy pan and sample container, a common source of error with fine powders.
• Anti-Pinch Motorized Draftshield Doors: Power-assisted side panels open hands-free via touchless proximity sensors, protecting ultra-light samples from air disturbance.
• 7-Inch Glass-Overlay Touchscreen: High-resolution color display provides a clear interface for entering tare values, switching modes, and reviewing results.
• Multi-Port Connectivity: Standard RS232, USB-B, two USB-A ports, and Ethernet allow direct connection to printers, PCs, and laboratory networks.
• Comprehensive Application Library: Over 15 built-in weighing modes including differential weighing, formulation, and pipette verification support diverse workflow needs.

Detailed Overview

The OHAUS EXP125/AD Semi-Micro Balance is built for labs where 0.1 mg resolution leaves too much uncertainty. With a 0.02 mg typical repeatability and a USP minimum weight of just 20 mg, it satisfies rigorous pharmacopoeial requirements for micro-scale weighing. The zinc-alloy pan measures 80 × 80 mm, appropriate for small vials and weighing boats, and remains easy to remove for cleaning. A four-tier user management system tracks operator activity, while the 100,000-entry internal log keeps an audit-ready record of every measurement session. Motorized leveling and the sample spotlight further support precise, repeatable setups. Optional Wi-Fi and Bluetooth dongles extend wireless data transfer to LIMS and ELN platforms when wired connections are impractical.

Applications

• Active pharmaceutical ingredient (API) micro-weighing
• Trace chemical and microanalysis sample preparation
• Reference standard preparation in calibration laboratories
• Formulation of high-potency compounds requiring microgram accuracy
• Verification of micropipette volume accuracy
