OHAUS AX85 Adventurer Semi-Micro Balance, 82g Capacity, 0.00001g Readability, AutoCal, Touchscreen, GLP/GMP

OHAUS AX85 Adventurer Semi-Micro Balance — 0.01mg Readability with AutoCal Reliability

When research requires weighing at the 0.01mg level, environmental stability and calibration integrity become paramount. The OHAUS AX85 Adventurer Semi-Micro Balance addresses both: AutoCal automatic internal calibration responds to temperature shifts without operator action, and the enclosed draftshield guards the 80mm weighing chamber from the micro-disturbances that matter at ten-microgram resolution. With an 82g maximum capacity, it handles most micro-scale analytical work comfortably.

Key Features

• 0.00001g (0.01mg) readability: Semi-micro resolution enables precise measurement of trace quantities, reference standards, and ultra-low-mass samples encountered in advanced analytical and pharmaceutical research.
• AutoCal automatic internal calibration: At semi-micro resolution, even minor temperature fluctuations introduce measurement drift; AutoCal corrects these automatically, preserving accuracy throughout extended analytical sessions.
• Integrated draftshield with 80mm pan: The enclosed weighing chamber, sized for semi-micro vessels and filters, eliminates air current interference that is especially destructive at microgram resolution.
• 8-second stabilization time: The measured settling period is appropriate for semi-micro precision, ensuring the displayed value reflects a stable, interference-free measurement.
• Full-color WQVGA touchscreen: The 4.3-inch display delivers sharp readout clarity at fine resolutions and supports the same GLP/GMP application suite as broader Adventurer models.
• GLP/GMP three-tier access control: Protects semi-micro calibration state—critical given the precision involved—and generates time-stamped analytical records meeting regulatory requirements.
• USB and RS232 connectivity: Direct LIMS integration enables automated data capture that eliminates transcription errors at the microgram level.

Detailed Overview

The AX85 occupies the highest-precision tier of the Adventurer family. Where other Adventurer models serve precision and high-capacity roles, the AX85 targets applications where sample masses are measured in tenths of milligrams—quantitative analytical chemistry, trace element preparation, filter weighing for air quality studies, and drug substance reference standard dispensing. AutoCal is not merely convenient here; at 0.00001g readability, a 1°C ambient shift can introduce errors that exceed a display division, making unattended calibration correction critical to data integrity. A repeatability of 0.00002g reflects a realistic performance envelope for semi-micro instruments in laboratory conditions. Minimum weight guidance of 20mg (USP, 0.1%, typical) helps method developers define appropriate weighing ranges for validated procedures.

Applications

• Drug substance reference standard preparation and potency testing in pharmaceutical QC
• Trace element and micro-sample analysis in analytical chemistry research
• Filter weighing for particulate matter and air quality analysis
• Gravimetric validation and mass calibration support in accredited testing laboratories
• Micro-formulation development in active ingredient and specialty chemistry research
