Steroglass · Water activity and product stability
aWLife
A chilled-mirror water-activity analyser with optical dew-point detection. It measures how available water is for chemical and microbiological processes, which is different from total moisture content.
Quick decision
Is this method right for your task?
Consider it when
Food, feed, pharmaceutical and cosmetic development and control where aW is part of a specification, HACCP plan or stability study.
We clarify before quoting
Sample types, required parameters and ranges, tests per shift, reference method, sample preparation and data requirements.
Another method may be better when
You need different parameters, measurement ranges, throughput, automation or confirmation against another reference method.
Best suited for
Food, feed, pharmaceutical and cosmetic development and control where aW is part of a specification, HACCP plan or stability study.
Capabilities and controlled parameters
- 0.030–1.000 aW range; ±0.003 aW accuracy at 25 °C; ±0.001 aW repeatability.
- 0.0001 aW resolution and a typical measurement time below five minutes.
- Sample temperature is adjustable from 15 to 50 °C and must be defined as part of the method.
- Seven selectable calibration points plus arbitrary single-point calibration.
- 7-inch touchscreen, user profiles, USB, Ethernet and RS-232.
- The method can be structured in line with ISO 18787; applicability and exclusions must be checked for each matrix.
Specifications have been checked against the official manufacturer page.

Implementation considerations
The final configuration depends on sample types, parameter ranges, throughput, accuracy requirements, and existing reference methods. Before proposing equipment, LabLog clarifies these factors and defines the supply scope, training, and method-verification plan.
How LabLog supports the project
- 01Capture requirements and compare suitable methods
- 02Configure the instrument, calibrations, and consumables
- 03Arrange official supply and commissioning
- 04Train operators in sample preparation and daily operation
- 05Provide service communication and repeat consumable supply
