OHAUS AX623 Adventurer Precision Balance, 620g Capacity, 0.001g Readability, AutoCal, GLP/GMP

OHAUS AX623 Adventurer Precision Balance — AutoCal Accuracy at 0.001g with Draftshield

Analytical chemists and formulation scientists working with fine powders, active ingredients, and reference standards need a balance that stays calibrated through temperature shifts without manual intervention. The OHAUS AX623 Adventurer Precision Balance combines AutoCal automatic internal calibration with a glass draftshield and 0.001g readability across a 620g range—keeping measurement confidence high throughout a full analytical workday.

Key Features

• AutoCal automatic calibration at 0.001g: Temperature-drift-triggered internal calibration maintains traceable accuracy without requiring the analyst to interrupt sample processing for manual weight application.
• Glass draftshield enclosure: Shields the weighing chamber from laboratory air currents that would cause unstable readings at 1mg resolution—essential in open-plan labs with HVAC or fume hood proximity.
• 620g capacity with 1mg display resolution: Accommodates full sample containers up to 620g while resolving individual sample masses to the milligram.
• 2-second stabilization time: Measured settling that reflects precision-level performance without excessive delay between samples in routine analytical workflows.
• Three-tier GLP/GMP user management: Separate access levels for administrators, supervisors, and bench analysts enforce compliance and protect calibration settings in shared laboratory environments.
• Dual USB and RS232 connectivity: Transfers time-stamped data directly to LIMS, laboratory computers, or label printers for complete analytical traceability.
• Security bracket and calibration lock: Physical security features prevent tampering with calibration state between formal verification events.

Detailed Overview

Within the 620g Adventurer product family, the AX623 occupies the position of highest laboratory autonomy: AutoCal handles calibration correction, the draftshield controls the measurement environment, and the GLP toolset manages documentation—freeing the analyst to focus on sample throughput. Compared to the AX623/E, which uses the same physical platform without internal calibration, the AX623 reduces dependency on the facility's calibration schedule. The 130mm circular pan suits standard analytical weighing vessels, and a linearity of ±0.002g confirms consistent performance across the full weighing range. Eighteen selectable measurement units, up to nine interface languages, and user-definable project IDs support multinational analytical operations. Minimum weight of 1.6g (USP, 0.1%, typical) helps operators identify appropriate measurement ranges for specific methods.

Applications

• Active pharmaceutical ingredient weighing and reference standard dispensing in analytical laboratories
• Fine chemical and catalyst sample preparation in organic and inorganic chemistry
• Density determination of samples requiring milligram precision
• QC check weighing of small-batch formulations in R&D and pilot-scale production
• Gravimetric analysis and loss-on-drying preparations

Why Choose the OHAUS AX623?

The AX623 addresses the analytical scientist's practical need: a 1mg balance that self-calibrates, shields its weighing environment, and documents its output without manual intervention at each step. It suits busy shared laboratories where multiple analysts need consistent, reliable data. Add to cart to equip your analytical bench with an autonomous, precision-ready balance.
